Title: Canon 50D
Post by: ayshih on January 07, 2014, 03:38:12 AM
It's not exactly a "new" port, but after a few weeks of unavailability, the 50D is supported again in Magic Lantern!  I'll be maintaining it, such as fixing bugs and also backporting remaining improvements from Tragic Lantern.  Nightly builds are available again from http://builds.magiclantern.fm/#/ (http://builds.magiclantern.fm/#/), so I encourage all interested parties to download the latest builds and provide feedback.  You can add issues on Bitbucket (https://bitbucket.org/hudson/magic-lantern/issues?status=new&status=open) or just comment here.  Thanks!

Installation:
1) Format the card from the camera.
2) Make sure you are running Canon firmware 1.0.9 (http://pel.hu/down/eos50d-v109-win.zip).
3) Copy ML (http://builds.magiclantern.fm/#/) files on the card and run Firmware Update.

Uninstallation:
1) Run Firmware Update from your ML card.
2) Follow the instructions.

Downloaded and installed it. It runs with no problems.
The changelog doesn't show anything.
Is there some specific feature you would like to be tested ?

It'd probably more instructive to look at the Bitbucket commit history (https://bitbucket.org/hudson/magic-lantern/commits/all), because each nightly build's changelog only shows the changes from the previous nightly build (attempt).  I believe the only recent 50D-specific change was to add a warning if the FPS gets locked to 22, likely due to overheating (http://www.magiclantern.fm/forum/index.php?topic=6537.0).  But, changes not specific to the 50D need to be tested as well: for example, over the past few weeks when it was not possible to download a nightly build for the 50D, there have been tweaks to the mlv_rec module, and it's always good to make sure that nothing was inadvertently broken on the 50D side.  Tonight's build, when generated, will include improvements to the information displayed during LiveView.  Test away!

Are you still interested in feedback about the ML port?

Definitely!  In particular, you should test out tonight's nightly builds, once they are built (will be magiclantern-v2.3.NEXT.2014Feb14.50D109.zip), because I added two important commits:
  • TL backport: display filters (ML grayscale preview, anamorphic, etc.) work now
  • mlv_rec: global draw is restored after finishing a recording
But test everything else too!

Yep I was testing it today.

Regarding the Global Draw. It tends to disappear after 3-5 recordings. I was able to reproduce the problem like this:

- turn on the camera \ LiveView
- first recording
- turn off the RAW recording in the movie menu
- recording "Standard" to .mov. Global Draw is ok
- turn back on RAW recording in the movie menu. now when you push Rec button you have 2 black stripes on the top and the bottom, BUT ALL INFO IS GONE
- on the next RAW recording, even black stripes are gone, visible is the whole screen with aspect ratio 4:3 or whatever

This is repeatable.

Because of the new memory backend, the nightlies were just rebuilt.  As long as you download the nightly that says "Built on: 2014-02-13 15:16:33 -0500" (or the equivalent time in a different time zone), you will have all of the recent changes.

Sorry, it was my mistake. I checked the .zip file - that is it! I wrote earlier about the GD.

Thanks for your testing report!  However, I'm not sure I understand your steps.

Regarding the Global Draw. It tends to disappear after 3-5 recordings. I was able to reproduce the problem like this:

- turn on the camera \ LiveView
- first recording
This first recording is using mlv_rec (as opposed to raw_rec)?  Is global draw set to "OFF" within mlv_rec?  What is the global draw behavior like?

- turn off the RAW recording in the movie menu
- recording "Standard" to .mov. Global Draw is ok
- turn back on RAW recording in the movie menu. now when you push Rec button you have 2 black stripes on the top and the bottom, BUT ALL INFO IS GONE
This just sounds like the normal behavior with mlv_rec with global draw set to "OFF" (the default setting).  That is, during the recording, global draw is disabled to improve the speed.  After you stop the recording, does global draw get restored?

- on the next RAW recording, even black stripes are gone, visible is the whole screen with aspect ratio 4:3 or whatever
I'm not sure why there'd be a difference in black stripes, but again, this sounds like the default behavior of disabling global draw during recording.

Did you start with a completely clean install of the nightly (e.g., no old settings files)?  Do you see different behavior when using TL?

Sorry if I was not clear.

INITIAL STATE: absolutely clean nightly after card formatting.

Turn on the camera. Turn on RAW recording with GD Allow. Several recordings go fine.

Then just switch recording from RAW to Standard. Recordings go fine as well, nothing changes.

Then I switch back to RAW recording (1584x892), making sure GD is set to Allow.

Now the GD during recording of RAW video starts to disappear. At first all texts and GD is gone, then the stripes disappear, so that while recording you do not have HD aspect ratio. It's a clean screen basically, with a camera sign and timer.

And yes, TL behaves the same way (( But if I use raw_rec not mlv_rec, this problem does not exist.

Another glitch: when zoomed x5 the screen flickers, when x10 it is ok, Have to turn zoom x5 off to avoid that. TL has slightly different glitch -- it is not flickering, it just goes b/w with an ugly low resolution, only x5 zoom.

Post by: rommex on February 14, 2014, 10:39:57 AM
Just tested the nightly ae5eb91aa8c0 (unified) tip

The problem remains.

In short: after switching off and on the RAW MLV recording, GD (partly) desappears during recording, even though GD is ON.

See the shot during the recording:

(http://i60.tinypic.com/255km5s.jpg)

The upper info and black stripe is gone, below is only waveform, no info.

Thanks for the clarifications and your later screenshot!  I now understand and can reproduce the issue, so I (and others) can look into fixing it.  I've been testing primarily with GD set to "OFF" in mlv_rec, so I hadn't noticed this issue with GD set to "Allow".  This is precisely why it's so useful to get testing feedback from many people.  My guess is that this is not a 50D-specific issue, but a broader issue with mlv_rec.

Another glitch: when zoomed x5 the screen flickers, when x10 it is ok, Have to turn zoom x5 off to avoid that. TL has slightly different glitch -- it is not flickering, it just goes b/w with an ugly low resolution, only x5 zoom.
You didn't say so explicitly, but can you confirm that flickering glitch is no longer present in the latest nightly build?  What you were seeing in the TL build (blocky, grayscale preview in crop mode) is what you should now be seeing in the ML build, and is the default behavior (preview is set to "Auto" in mlv_rec).  You can set preview to "Canon" in mlv_rec to get the normal Canon preview, but the framing is off in crop mode.  The Canon x5 preview shows only a portion of the image that will actually be saved.

Not at all, man. I'm glad to make a tiny contribution to the big ML thing. Cannot promise a thorough test, but I am certainly willing to test against my workflow.

You are right, the second glitch is gone -- and the "ugly" bw picture indeed replicates the crop mode view. Amazing!
The only drawback is that when I start recording in cropped mode the bw picture on the screen is renewed approx at 1 FPS rate. VERY slow. If you need more detailes about this, I can shoot a small video. Let me know.

And thanks for your efforts! (I am a fan of TL and it will be great to bring its benefits into ML homeland).

Any news on the progress with the 50D Global Draw issue?
If you're referring to rommex's specific issue, I haven't yet put in appreciable effort to track down the bug, so the short answer is no.  Are you having other issues with Global Draw?

I've had issues with my 50D locking up on me, which never happened before.  This was with the March 9, 2014 build.
Can you reproduce these lockups, or at least provide some more information about what you were doing?  Can you try the latest nightly build?  There was a bunch of cleaning up of the ML code just after the March 9 nightly.

Hi ayshih,

Thanks for your work on 50D. Currently i own a 60D and 5Diii. Unfortunately the 60D's RAW capabilities are not that good due to slow SD card writing.

Just as an opinion, would you suggest getting a 50D as a "cheap" RAW B-roll camera as company for my 5D as the main camera? Of course, cheap is relative  :). Since i don't own a 50D yet, do the two combine good together, feature wise?
Title: Re: Canon 50D
Post by: ayshih on March 27, 2014, 08:13:55 PM
I actually rarely use my 50D for video, so I can't give an informed opinion.  There are plenty of others  on this forum who do, so hopefully one of them can chime in!

I love the 50D. Non crop max resolution is: 1584 X 1058 continuous and in crop 2000(1920) x[1080  2:1/ 980 continuous . If that works for you go for it.
The footage graded and with a LUT reminds me of super 16mm footage. I wouldn't consider the footage from the 50D quite as perfected as the footage from the 5Diii. But everyone has a different opinion.

I loaded the latest build 3.27.14 and the first thing I noticed is that I was able to set the Shutter to 1/48 which had been an issue for me in the past.  I saw that the resolution had increased a bit to 1568x882.  I'm using a Komputerbay 32GB card.  I did notice that it takes longer for recording to actually start now.

The 1st time I tried to record it lasted just about a minute and then the camera reported 1 skipped frame and locked up, so I had to remove the battery.  After that it recorded for 5 minutes straight with no issues whatsoever. 

I noticed that at the start of a new recording the 3rd time the little Green Camera icon flashed Red and Yellow a few times before staying solid green as it started recording.

I also noticed that the remaining free Storage space doesn't update after a new recording until I turn the camera off and back on.

This is MLV Rec on
1568x882 
Global Draw on all modes
Zebras on
Spotmeter on
Waveform Small on
FPS Override on 23.976 (Exact FPS)
Expo. Sim on
LV DIGIC Peaking on
File Manager on
MLV Play on
Picture View on
Camera temp was at 48C after all the recording.

Will do more testing and report anything else I find.

Post by: rguk on March 28, 2014, 09:27:45 PM
Alright, I think I've determined that live view juddering and frame drops while changing aperture while recording is a hardware limitation and that the 50D is essentially useless for manually riding the exposure with a EF/EF-S lens and that it's only possible with a manual lens with aperture ring. If this is wrong then someone please correct me.

That aside, I notice in the stable build and in a certain 3rd party fork that I won't mention (the last time I did, the thread got wrongly moved to an area of the forum I have no access to) I can adjust the aperture (or other exposure settings) while recording video (H264). This doesn't seem to be possible in the latest nightly, using the camera wheels do nothing other than change the indicated value on the top LCD. Exposure override is enabled and exposure lock isn't on. If I enable Av adjustment on the joystick, the camera locks up if I attempt to adjust them while recording. If I reboot the camera and try to use the joystick again to say set the ISO, sometimes the display corrupts and flashes and the camera requires a reboot again. If this is all unclear I can take a video of the problem.

Aside from that, very happy to see the 50D back in the mainline nightly builds! I have a variety of lenses and CF cards for any testing required. Fastest is a Komputerbay 64GB 1000x.

So I've also got the above issue with not being able to adjust aperture and so on with the wheels while in Liveview. I have to go to the exposure page of ML to adjust.

Also I now have VERY pink frames while processing the MLV files with raw2cdng. I did now have this before with a third party modification I will not mention here. Does anyone else have this?

For me I will not be switching to Nightly just yet.

Glad to hear it's not just me. Could you confirm that if you adjust the aperture while in live view (in a version that does let you do it) that the live view freezes briefly which also affects recordings? I've still not had any confirmation of this from anyone.

Could you tell me, how to enable crop mode and 24 fps on 50d ?

Crop mode: press the "5X" zoom-in button.  Depending on your preview settings for RAW recording, you may see a black and white ML preview, which shows the full extent of the recording but has a slow refresh rate, or you may see a Canon preview, which refreshes fast but only shows a portion of what will actually be recorded.

24 FPS: use Movie > FPS Override

Well.. not quite...you will see part of what ( a large percentage of what) you are filming in the viewfinder but the area that you are filming/ recording will be somewhat greater than the area that you are seeing in your viewfinder. Particularly width wise.
 Similar to a lot of film cameras that would give you about 90-99% of your picture in the viewfinder. In other words; in crop mode the area that you are filming is slightly greater than what you see in the viewfinder

The 1st time I tried to record it lasted just about a minute and then the camera reported 1 skipped frame and locked up, so I had to remove the battery.  After that it recorded for 5 minutes straight with no issues whatsoever. 

I have same problem on my 50D. Right now Im on nightly from 22.3. and it was same on older build from beginning of March. I will try it again on latest nightly build soon and report back.
I get those "1 skipped frame lock-ups" very often. About 1/4 of all cases and it is very annoying as you must turn it of, remove battery, turn on (then it skips modules) so you have to turn off again and then on. Now I have next try :o) Sometimes problem repeats couple of times. This drives not only me, but even my unpatient wife very CRAZY :-)
Scenario is always the same. I start recording. 50D starts record session and displays indicator on screen. Now it either continues smoothly without any problem, OR it indicates 1 skipped frame and immediately crashes. Now you are not able to stop recording or do anything else... RAW file is not saved. This happens in both full sensor mode and in crop mode.

Im set like this:
This is RAW Rec on
1568x882 
Global Draw on all modes
Zebras on
Spotmeter off
Waveform off
FPS Override on 23.976 (tried both Exact FPS and optimize for Low Light)
Expo. Sim on
File Manager on
RAW Play on

Using Komputerbay 64 GB 1000x card

So now we know that problem is in both MLV and in RAW recorder. What I want to try (if this will still happen on latest build) is to set frame skipping to be allowed. Now I have it set to stop on skip.

Let me know if you need any further info or something to try... I will update in next few days.

Just want to say the 50D is well worth the continued magic lantern updates until perfection is attained.  I recently acquired a Mosiac Engineering VAF-50D Optical Anti Aliasing filter and did some test footage with it.  Needless to say I am very happy with the results and quality.  You can see the footage here:


Will also be testing some low light/ night time footage as well, which from what Ive seen so far is pretty clean.  The 50D is a better performer in low light for RAW capture than the 5D MKii and 7D!  At only 25% less resolution than the 5D mkii, its surly worth the price to pick one up.  I'm also shooting a short film this weekend and will post the link to that as well once its edited.

Your footage shows it! It is even better than what I expected! 50D + VAF is killer combination. I cannot wait longer for my VAF filter - just ordered it few days ago ;o)

Here is what I got last weekend - shot mostly in full sensor without VAF:
Using Cineform RAW workflow to Adobe Premiere - that is pretty awesome too :)

Yes it's amazing, definitely turns it into a different beast. I'm now considering selling my 600D body to buy this filter. Arrgg tough decision.

Once I will have it in my hands I will make some test footage in the city (tried that couple of weeks ago but most of full sensor shots was unusable due to excessive aliasing and moiré). Now I only hope it will arrive soon...

Post by: LEVISDAVIS on April 16, 2014, 01:20:07 PM
I've got a prototype 50D VAF from Mosaic that doesn't hold up quite as well as Sync24FPS... It's a big deal having a picture perfect image. I'm honing in on my skills with RawTherapee to see if I can improve upon the last little bit of moire.

Anyway, the 50D seems to be perfectly aged for recording .RAW. It's not too clean, not too dirty, plenty of detail, and blows up to 4K 4.2.0 no problem.

... Downloading the latest ML and will post test results if necessary.

Definitely agree and particularly the not too clean not too dirty part! Love that about the 50D
Question about the 4.2.0 blowup to 4K. Why 4.2.0? Not 100% sure why. Is it pure resolution numbers, ie 1586 x 1080 1054 (or so) ?...or 1920 x 1080 or so in crop mode? ??? Not quite sure.

Thanks.
Title: Re: Canon 50D
Post by: LEVISDAVIS on April 17, 2014, 09:28:45 PM
The 4:2:0 relates to the amount of information contained in the shot. The 50D is a 14bit 444 image at a resolution near 1600x900. If you blow up the image you have a near 4K 4:2:0 native equivalent. More importantly, it's probably closer to a 10 bit 4:2:0 luminance/chrominance than an 8bit.

*** Most of the latest camcorder and DSLR gear will shot a native 8-bit 4K 4:2:0. It will have a sharp picture but will fall apart in the gradients. What that means for 50D shooters is that you are capturing footage with a softer, yet smoother transitioning image. An image that can be more cinematic in nature than the 8bit 4:2:0 4K that down samples to 10bit 4:4:4 Full-HD native equivalent. Apples to apples, the 50D is more than likely capturing the equivalent of a 12bit 4:4:4 Full-HD image/data equivalent even though it is a native 1600x900.

*** In a recent test, I was able to get a sharper image with a 50D / VAF combination than the Full-HD BM Pocket Cinema Camera. The Pocket Cinema was falling apart in the moire department and couldn't withstand the same up convert process as well as the 50D with the VAF. Apples to Apples, the Pocket Cinema was shooting a native 12bit 4:4:4 Full-HD image.

Obviously you can't change the sensor, but you can capture every last bit of information that the sensor has to offer. The freedom that this provides truly allows for a multigenerational capture acquisition... The type of camera that is now nearly 6 - 7 years old and still has a place at the frontline of prosumer equipment. In essence, it's a very powerful statement and a wise investment for image capture acquisition. Maybe the best?

WOW ML!!!

Chroma subsampling changing by simply upscaling? Are you sure about that?  ???

Post by: sync24fps on April 18, 2014, 05:42:15 AM
I just wrapped shooting a short film with the 50D and noticed when trans coding that one of the important shots is corrupted.  It plays back fine in the camera with the MLV player but when transferred to a computer, its really dark and has funky colors.  Is there anyway to recover this file/ footage back to normal?  Why would it play fine and look normal in the MLV player then when put on the computer be all messed up? Please help.  Thanks!

I suspect it's your card reader. Try and use a usb3 card reader if possible. I have a CF card reader on the front of my machine but it messes up stills and video from my Komputerbay cards which work fine from a card reader plugged into the USB3 port at the back. Other than that try transferring the file again or recovering it if it's been deleted but not overwritten.

Post by: sync24fps on April 19, 2014, 07:14:48 AM
I did try and delete the .IDX file and also am using a Lexar UDMA 7 card reader USB 3.0     When I try to convert the footage using the MLV2DNG converter I get this message in the DOS window before it starts:

Exception! Header not recognized: 'STYL'

Exception! Header not recognized: 'MARK'

The frames do render out but look really funky with odd colors and very dark.  Are there any programs out there that can recover a corrupted DNG sequence back to normal do you know?  Again it is playing as it should using the MLV player in the camera off the card.   All my other footage is OK except this one file and its an important shot that we need.  Any other help would be greatly appreciated...

It might not be the card especially if it's reading the other files properly. It's just that I was reading this http://www.magiclantern.fm/forum/index.php?topic=9747.msg93779#msg93779 (http://www.magiclantern.fm/forum/index.php?topic=9747.msg93779#msg93779) which does mention your card reader. I've had files which have refused to copy 3 or 4 times but with persistence have copied properly. I don't know why. I also have some corrupt mov files I'd like to rescue but can't find a way of doing it.

SYNC24FPS if you are using a Mac I am writing a document here on how to repair .RAW files... Should be the same for .MLV. Anyway, this same information can be found by searching for "Damaged Header or Damaged Footer" in the forums...

Here is a process to fix corrupt files... Admittedly, it may seem like a lot of work for someone just wanting to shoot RAW, but we both know the image quality is well worth the additional exercise, right?


STEP 1:

This first step is for spanned files only. Spanned files must be merged into one file in order to be repaired. Here is how to merge them together on a Mac.

1. Place copies of all the spanned files on the desktop.

2. Open the program “Terminal.”

3. Type in “cd desktop.”

4. Use this code and replace "file.name" with the name of the corrupted spanned files...   cat file.name file.name file.name > file.name.ALL.MLV

This is the process to join RAW or MLV files… Here is an exact copy of the files that I merged together... cat M07-2056.RAW M07-2056.R00 M07-2056.R01 M07-2056.R03 M07-2056.R04 M07-2056.R05 M07-2056.R06 M07-2056.R07 > M07-2056-ALL.RAW


STEP 2:

1. Shoot / Open a file in HexFiend that is similar in record length. Too short and you will cut off your shot prematurely. Too long and you will create empty/black DNG files. Be sure to have the same image resolution and frame rate too. *The black frames are easy to delete.

2. Scroll to the bottom of the HexFiend window or similar program and copy the letters and numbers starting with A5 A5 A5 all the way to the end of the file...

"A5 A5 A5 A5 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 52 41 57 4D 00 05 D0 02 00 A0 18 00 D2 83 00 00 01 00 00 00 C0 5D 00 00 00 00 00 00 04 69 81 FF 01 00 00 00 28 16 2A 06 3C 04 00 00 80 06 00 00 60 0B 00 00 80 2A 30 00 0E 00 00 00 FE 06 00 00 98 3A 00 00 00 00 00 00 00 00 00 00 36 06 00 00 22 04 00 00 1A 00 00 00 4A 00 00 00 3C 04 00 00 80 06 00 00 00 00 00 00 00 00 00 00 00 01 01 02 01 00 00 00 38 13 00 00 10 27 00 00 68 02 00 00 10 27 00 00 AF FD FF FF 10 27 00 00 A3 E6 FF FF 10 27 00 00 A4 32 00 00 10 27 00 00 E0 0A 00 00 10 27 00 00 12 F9 FF FF 10 27 00 00 6A 0C 00 00 10 27 00 00 5D 1B 00 00 10 27 00 00 F2 03 00 00"

3. Leave the window open and then open the merged / damaged file in HexFiend.

4. Scroll to the bottom of the recording and locate the A5 A5 A5... If the A5 A5 A5 information is not located in your shot you will need to simply paste the information from your clipboard to the file. If the A5 A5 A5 is in the shot, simply highlight all the letters and number from A5 A5 A5 A5 and beyond and paste the new information on top.

5. Save the file to your desktop and/or to another location.

6. Now process / transcode the new MLV / RAW file using the converter of choice.

*** Note, the information from A5 A5 A5 up to the 52 41 57 appears to eliminate issues with pink frames. The information after the 52 41 47... relates to the number of frames in the shot. ***

Again I am using windows 7.  Thanks!

Also the file was shot as an .MLV  so there are 4444 frames and three files to the clip -  .MLV  .M00 and M01 and total size is 9.62 GB and runs 3:05

Post by: LEVISDAVIS on April 21, 2014, 10:06:55 AM
... There is also an option to leave the spanned files separate and use your Hex Editor to repair the file...

1. Open the last spanned clip in your donor shot with your Hex editor...

2. Copy the information from the "A5 A5 A5..." down to the very last line of information.

3. Open the last spanned clip in your damaged shot.

4. Paste the "A5 A5 A5..." from the donor shot onto the damaged shot in place of the existing "A5 A5 A5..." or at the end of the file if there is no "A5 A5 A5..." listed within the last 100 or so lines of your HexEdit window.

5. At that point, you have to "Save the File." This is actually writing your final spanned file with an ending header.

6. Place the newly written final spanned file into the batch of your other pre-spanned files.

7. Convert the files using your MLV converter.

Should be good to go. Boy is it ever exciting when it's good to go!

Levi you rock!  Thanks so much for the guidance and instructions!  When I changed the header in the .MLV file and the footer in the last spanded file with the HEX file editor, the file was repaired and is now rendering as it was shot!  At first though the MLV converter program was not working.  It was only rendering out the first 1800 or so frames but when I switched to MLV2DNG script, it rendered all the frames perfectly!  Thanks again Levi, you saved the day!

In fact, it is best to move the mlv file to a hard disk, then convert from there.

I've finally gotten a chance to put the 50D to the test in a real world production situation.  I was on a short film shoot that ran 8 hours with a total of 72 minutes of RAW capture footage. Here is what I have to report about its performance:

Given that I know the 50D has a reputation of overheating, I tried to minimize the chances of this happening while shooting by using a original Canon battery grip to help minimize the battery heating up the camera and by using an external monitor via HDMI out.  The 1080i signal produced by the 50D I found was great for external monitoring and checking focus. 

Pros and Cons:

Pros:  The 50D is an amazing performer in low light with just enough noise at the higher 320 and 640 ISO ranges to give the images a classic "film stock" look.   The image quality while shooting the RAW is amazing as well and blows up to 2K with ease in Resolve.  Overall a great image is produced that would hold up its own if projected on a large theater screen.

Cons:  It is with great disappointment though that I have to report that despite the incredible image quality the 50D captures, overheating seems to be a major issue.  Production flow was halted multiple times by frame skipping and camera freezing up.  Even turning the camera off in between takes for a few minutes had minimal effect in preventing the sensor from getting hot quickly again. 

After a shot of 3-5 minutes once the sensor temperature raised above 40 degrees C, the frame dropping and camera freezing issues started.  To remedy this, when the camera went above 45 degrees C, I had to turn it off for at least 5 minutes and switch CF cards to enable me to capture another take over 3-5 minutes continuously.

The cards I was using for the shoot are the Komputerbay 64BG 1000X.  Perhaps a Scan Disc or Lexar may hold up better for continuous recording as the camera heats up, but eventually when the camera reaches 50 degrees C and is in the yellow, regardless of cards, I think it should be turned off as it has no auto overheat protection.

It is this overheating issue that makes me think the 50D is not suitable for any long shoots.  Canon probably disabled the video feature originally because of the overheating, that at the time, they had no solution for until the 5D mkii was released.  Just my guess.

The only solution for long hours of shooting with the 50D would be to have TWO cameras on standby taking turns taking shots to avoid the overheating.  In fact this is what Shane Hurlbert used to do when the 5D mkii was released to avoid overheating auto shutdown.  But Shane shot loads of footage for his projects.  So it is an option.

However when considering buying two 50Ds to switch off and alternate cameras to avoid overheating seems like it will slow production time down.  In  addition, for the price of two 50Ds one can get a 7D cheaper or one 5D mkii, which as we know, both have higher capture resolution.

Perhaps Magic lantern will come up with an option to solve the 50D overheating issue in the near future but I think this seems to be more of a camera hardware  functionality.  I know even the RED MX had overheating issues that were dealt with with ice packs at the time. The question is,  do we really want to have crew and actors wait around while a camera cools down and run the risk of corrupt files?  I guess its up to you to decide.

That said, for now, my 50D remain a "B" camera for night time exterior establishing shots (and WOW is it great in low light).  But for main "A" camera shooting, I'll be going with the 7D or 5D mkii for the next RAW production.   Hopefully these will not overheat as the 50D does.

Hey Alex, is there any hope of getting dual ISO on the 50D? The 50D could benefit from this even more so than the 5D3.

It's no longer working? I already have a few 50D samples in my test collection.

That makes sense, but since the video workflow was not exactly usable (aliasing, flicker, slow processing), I didn't see this as a priority. Would require some extra reverse engineering though, not just porting the memory addresses.

Would be very cool to have a video workflow that looks at before/after frames to reduce the aliasing, but that's not quite easy.

 I would definitely agree there are newer cameras that are less prone to overheating issues.  But what a nice image.

Anyone else use Silent Pictures for crop mode?

The center of the sensor in crop mode seems to not like to center... Confusing, I know. What I mean by that is that you can get information from the center of the sensor, but when in crop mode, it always chooses a side (left/right).

I know it is a 5x preview of a 3x crop, so it is already a bit more to think of while composing a frame. It would be nice to know what is actually the center without having to guess.  This is also the case for crop sensor RAW recording. Being able to have it record from the center would be great, allowing for zoom in/outs would not come/go to the corner of the frame, but straight down the center of the lens.

Thanks

Hi dsManning. I went through this a few months ago myself. As far as I know there's no way to center the framing in crop mode. It must be something about the 50D. If you search the old thread it's discussed a few times in there.  http://www.magiclantern.fm/forum/index.php?topic=5586.0

Dual ISO video is the same as on 5D2 (so once I'll get it working there, it will work on 50D too).

Silent pictures are limited by FPS override (not sure what's the lowest limit on 50D, you can try and tell us). But you can average a few frames and get a long exposure (with higher dynamic range - if you average 16 frames you get 2 stops, if you average 64 frames you get 3 stops and so on). I have an old patch that does this averaging directly in the camera, if anyone wants to get his hands dirty:

Im now turning frame skipping ON (as it crashes just AFTER first frame skip) and fps from 23.976 to 24. Tommorow I will try it another day to see if changed settings make some difference. Any better ideas?

Still same. But now it most of the times only skips frames and does not crashes. Can anyone help me or do I have to stop bothering you guys? Maybe Im missing something important. I do not know, Im new to the whole ML thing...

On 5D2, CMOS[1] and CMOS[2] control the horizontal and vertical position of the raw feed. If you lock thier values from adtg_gui (override them without changing the value), the raw image will stay locked in the same place, no matter where you move the focus box on the screen.

To see this, you will have to use the raw_rec grayscale preview with recording resolution set to maximum possible. If you use a lower resolution, raw_rec will try to center the recorded crop area with the displayed area, but with the maximum resolution there are no degrees of freedom to do this. Just so you know, finding the displayed area is done with focus_box_get_raw_crop_offset (also used by the x5 centering trick).

To implement it as a useful feature, we will need:
- the CMOS values needed for perfect centering of the raw stream
- a place to patch these values passively (need to look in the firmware)
- user interface proposal (menu option? or just enable it by default when centering the focus box? don't know yet)
- when this centering mode is being used, we also need to skip the raw centering process in raw_rec/mlv_rec, since focus_box_get_raw_crop_offset will now return nonsense.
- update the x5 centering trick for the new raw buffer (this trick centers Canon's displayed area on the raw buffer, so Canon preview will always show the center of what you are recording), preferrably in the backend, without showing it on the UI (aka it should just work).

Can this be overheating issue?

Done more testing yesterday at home (indoor). Formated card (64 GB 1000x Komputer Bay), started recording in full sensor mode and let it record almost full card in few long takes. No problem at all. Temperature started at about 30C, quickly raised to about 40C and stayed here. No frame skipping issues or crashing. Now Im little confused. Maybe higher outside temperature (on sun) plays some role here. Will keep trying outside and watching temperature carefully. I hate to discuss with myself, but hopefully my findings may help someone else in the future :-D

2, In-camera card benchmark - crashed after while. Temperature was low (cannot remember exactly, but I took camera and started benchmark without any warm-up). It crashed. Now Im suspecting my Komputer Bay 64GB card and will focus on it little bit more. I want to try reformatting it in computer - some useful info I found is here: http://www.magiclantern.fm/forum/index.php?topic=6554.100 ("Aligned + 64K clusters is giving me the best speeds.. expect a 1-2mb cut from formatting in camera to 32k clusters.

Hi y'all,
     Made this little video with some footage I shot in Massachusetts a month or so ago. Terrible weather the day I was out shooting and touring the countryside. But I was impressed with the 50d's ability to handle the rain, no problems. I would wipe it down every so often and kept it kinda covered. Anyway. RAW to DNG (using Rawanizer) to Davinci (color correction/grading) to AE (for editing, slight sharpening, stabilizing, upscale to 1080) to H.264.

Created a short piece for a charity.
This is my 1st attempt at videography, let alone raw video. Any criticism is highly appreciated. I will Vimeo it soon.

Majority shot at 1920x1080 (5x crop mode) Raw, using the kit IS lens.
The first and last shot is at 1584x1058 full sensor (hence the moire/aliasing).
Went straight from Rawanizer into ProRes444 proxy for editing in After Effects.
Finally, exported to .mov (probably a mistake).

Simple but effective workflow, but wish to optimize this in learning more complicated workflows that I keep seeing.

Hi podkan,
    My guess is you haven't enabled the raw_rec module in the modules menu. In the Magic Lantern menus, the modules are one of the menus toward the right. In there enable all the fun stuff; raw_rec, mlv_rec, etc. Then turn your camera on/off, and RAW options will appear in the magic lantern movie menu.
    Don't know about your second question, haven't tried that yet.
    Good luck!

Great! I'm glad it works now. Now you have the whole can of worms that is post processing to deal with! :) Don't worry though it's super fun.

And yes you can play RAW, and MLV clips back in-camera. I forget exactly what modules have to be loaded, I'm pretty sure it's mlv_play, and file_man. You can then play clips from the file manager found in the Magic Lantern menus, or you can play clips by pushing the normal "play/preview" button. Doing that also has some controls for navigating to different clips and playing either in color or black n white.

The short answer is that it's not ready yet in an easy-to-use fashion, for any camera.  It's possible to "enable" by modifying the ADTG registers, but I would recommend the casual user to wait until something straightforward (and safe) is available.

Hi all,

I've been lurking in the forums, and finally got my 50D installed and working. I'm not proficient in computer coding so I can't contribute by helping with the builds, but I did go ahead a document my install and set up process, as I found I had to search a lot far and wide to figure out how to get everything working.

There are two posts, one on installing, and the other on setting up and recording.

http://altcinema.com/2014/05/10/diy-filmmaking-and-the-canon-50d/ (http://altcinema.com/2014/05/10/diy-filmmaking-and-the-canon-50d/)

I hope people find it helpful!

Oh, and here is my test footage. I was only able to get up to about 1400 frames in 1920x1080 with the Transcend 64GB 1000x card, which maxed out at 81MB/s, so I am sending it back in favor of the Komputerbay, which I found out after the fact seems to be getting faster results.

Dear drkamikaze,

I found some conflicting info and I'm not sure which is right.
You've written in your article:

"In the Canon menu, change your record settings under the first red menu with a camera icon to JPEG and turn off raw.  You do this under the “Quality” menu. Also, make sure Exposure Simulation is on, which you can do under the second yellow wrench > Live View function settings > Expo. Simulation. Apparently this helps buffer speeds."

But in the first post of Topic: How to record: -- 30/24/25 fps RAW VIDEO ON 5D3 & others (http://www.magiclantern.fm/forum/index.php?topic=5451.0) there's written:

Latest findings to prevent frame drops:

You should check that in Canon Menu:
Image Quality = Raw
Auto Lighting Optimizer = OFF
Long exp. noise reduction = OFF
High ISO speed NR = OFF
Highlight tone priority = OFF
Multiple Exposure = Disable
HDR Mode = Disable HDR

So it seems Image Quality should be set to RAW.
I know that post hasn't been updated since september 2013 and it has been written for the RAW_rec module (instead of the MLV_rec) but I suppose those settings still apply. Maybe you can update your article with above settings?

There are two posts, one on installing, and the other on setting up and recording.

I hope people find it helpful!

Oh, and here is my test footage. I was only able to get up to about 1400 frames in 1920x1080 with the Transcend 64GB 1000x card, which maxed out at 81MB/s, so I am sending it back in favor of the Komputerbay, which I found out after the fact seems to be getting faster results.

I've been testing my two 64gb 1000x Komputerbay CF cards today on my 50D with the MLV_rec and RAW_rec module. I'm looking for settings that would allow true continuous recording until the card space is filled up. I was thinking it should be possible with these cards and MLV_rec, but I can't get reliable/consistent results. Recording always stopped after a few minutes. The settings I was using were:

In the canon menu:
Image Quality = Raw
Auto Lighting Optimizer = OFF
Long exp. noise reduction = OFF
High ISO speed NR = OFF
Highlight tone priority = OFF

In the MLV menu:
Resolution: 1568x882
Global Draw: off
Frame Skipping: on
Preview: Hacked No Prev
Status when recording: debug
Extra Hacks: on
Fix black level: off
Show buffer graph: on

I've tried various settings and both cards, but I supposed the settings that I just mentioned would deliver the highest write speeds. Though, I didn't achieve continuous recording. I tried lowering the resolution a bit, but the buffers continued to fill up after a while.

Trying RAW_rec worked much better for me and I was able to fill up the entire 64gb in one shot. Does any of you get continuous recording with MLV_rec on the 50D with Komputerbay cards? I'm wondering if I should return my cards... I'm using magiclantern-Nightly.2014May08.50D109.

Has anyone else noticed that the max resolution has dropped from 1584 to 1568 wide? I guess this isn't a huge deal, but what gives?

Also, the latest nightly I downloaded doesn't seem to have mlv_play on it :(

Can someone help me understand the shutter speed values displayed on Live View? After upgrading to the most recent nightly build, (after using V2.3 with this RAW build - http://www.magiclantern.fm/forum/index.php?topic=5586.0) my shutter speed values are now confusing me.

My camera's setting, (based on the top of my camera) is on 1/50, since I shoot 23.976 and the fewer frames offer greater resolution shooting.

BUT in Live View it reads a completely different shutter speed and the Live View picture is whitewashed when shooting outdoors, (even though photographs I take with the same settings are exposed correctly). For example, the camera is set to 1/50, but in live view it will read as 1/92 (or any number it would like to). In fact, even when I adjust my aperture I've found that this number changes. I'm not certain of how my frames are being exposed. I also get confusing readings within the ML menu, like "1/92, 94°." When this value is changed within Magic Lantern, my photo settings change on the top of my camera as well. It also appears to loop around through settings when I rotate my click wheel far enough.

All in all, I would like some help in setting an accurate solid shutter speed for 23.976 fps raw video recording, and an understanding of what these units represent. Do I follow what's on my camera's top display or what ML tells me?

Regards and much thanks, ImagineFlight

Thanks for the response! It's nice to have some sort of lead.

Can you help me understand what my values represent then, reading as  "1/92, 94°?" I'm having a difficult time reaching my desired 1/50 or 1/48 value for the 180° shutter rule. Nothing worse than bad blur for filming, looks terrible! Also - why does this value change depending on the light? Am I not in full manual mode for some reason?

I'm thinking of buying a fast CF card to shoot raw, but i'm not sure which one to buy. Because there are so many mixed reviews on different sizes, speeds and cameras.

-For the 50d how fast does it need to be to shoot raw? 800x?
-Are the komputerbay cards trustworthy?

Get cards at least UDMA 7 or 1000x write speed. I had a defective Transcend 32GB and a 16GB, so i don't recommend that brand (althought it could have been because I was using a USB 2.0 card reader. ALWAYS use a USB 3.0 card reader).
I use Lexar 32GB 1000x and Sandisk 16GB 60mb/s with no issues on 1584x896 23,976 fps.

This is the closest to the problem I've been having that I could find. The last build I could use on my 50d was back in December. Ever since then I've had next to no control over the shutter speed, and I get a flashing screen as if it's hopping from ISO to ISO. In the past this would happen only when I tried to change the ISO, but with the latest build it starts doing it a few seconds after I turn the camera on. If I switch off LV I can set any shutter speed, but as soon as LV is back on it goes haywire again. For me the builds just keep getting worse and worse!

This behavior is present when you're not in M mode

or if you're in M mode exposure override OFF

If you don't want it to happen, turn exp override on

Ive been having similar issues with shutter speed changing on its own, when I change the ISO or use the 5X crop, the shutter speed changes on its own.  Its frustrating because we don't know if its a glitch or the SS is actually changing effecting the image. I guess down the road the ML team will fix this.

@ arboldeconfianza -  I tried using the tool you recommended to change the Black level setting but with no luck.  Nothing is happening.  Also, since a 50D is a 50D, why should we have to change the BL in the first place?  Shouldn't there be a standard setting within the ML itself when installed that fixes it by default use?  It really suxs that i cant get any of the latest builds to look normal on my 50D - they are all extremely pink/ magenta and can not be corrected.  I know its apparently a soar subject to bring this up, but the latest version of TL does not have this issue except a SLIGHT magenta shift that can be adjusted in CC.   TL was on the right track to perfecting the 50D.  I get amazingly beautiful creamy ALEXA like images using TL and processing through resolve.  TL still did have some issues that I thought the latest version of ML would have addressed by now....Please, dont give up on the 50D - its looks amazing - even better than the 5D mkii when processed right!

I definitely agree. The 50D is an animal when it comes to RAW video.

Using the most recent nightly build, I've discovered that using the MLV format comes out pink and un-correctable like you said. However, the classic raw format still works perfectly, now that I've learned to use the Exposure Override function. MLV on the 50D isn't a very plausible format for the 50D, since the 50D lacks in audio recording capability (which seems to be the point of MLV). I recently shot a promotional video on my 50D in classic Raw v1.0, and all my frames came out perfectly (almost - one was corrupted, had to adjust the Hex values with HxD).

I definitely prefer my personal build using Stable Build v2.3 and this raw build here: http://www.magiclantern.fm/forum/index.php?topic=5586.0

It provides the basic manual controls I always look for. However, your personal RAW preferences are lost on reboot - i.e. aspect ratio and the like.

Also, check this out - http://vision-color.com/visionlog/ I've been using this with ACR. I always color through ACR for a realistic image. This camera profile helps me achieve that and gives me solid working ground.

Hey Alex,
The biggest issue I run into with the new builds is the lack of shutter speed control. With my classic 2.3 build with raw, I have complete control. With the recent nightly build, setting my shutter speed is a nightmare. And when shutter speed is set incorrectly, video appears to stutter or have out-of-control motion blur. I have no clue as to why someone decided that shutter speeds needed to be set automatically and change alongside my ISO and aperture settings, but it's made working with the new builds extremely difficult. I can set my own controls manually and get fantastic video. With the new ones, it's like getting drug into a rabbit hole of confusion. I've tried a few days working with exposure override, and while it works, it's still not simple and easy like it used to be.

I have missed your previous posts requesting information regarding shutter speeds. Let me know what you want, and I'll get it to as fast and best I can.

Keep being awesome,

If you don't have coding skills, show me a video with the exact differences between the two builds (I don't have a 50D).

If you have coding skills, let me know how the exposure-related properties react in 50D when Canon decides to adjust the exposure automatically, e.g. when moving from inside to outside (test code linked above; a video showing the reaction of these properties would be perfect).

FYI, the 50D's video mode is similar to the one from the old 5D2, that is, without manual exposure controls. Therefore, ML adds them via exposure override (and, of course, should not sync to Canon's auto-exposure code).

When I started looking into RAW last week I tried MLV first, but all the clips had the magenta shift. I disabled fix black level in the MLV settings and after that the color was correct. However, I'm now using RAW_rec instead of MLV_rec because it gives me much more consistent performance. I would suggest you to turn off fix black level in the latest build to see if that helps or use RAW_rec. Seems to be working for me. I'm going to use it for a shoot tomorrow, excited!

Everyone who is having trouble with shutter should try the expo Override. At least it solved my shutter problems :)

The problem's that I can only do it by accessing the menu, it's bit awkward when not using manual lenses, not to be able to use the top and back wheels to change the aperture and shutter speed.

I have a copy of one from December and one from October. I'm having a whole new issue now though, and it applies to those as well as the latest, all the same - namely, none of the exposure settings are working. I can't control shutter, and I can change the numbers for aperture and ISO but they have no effect, at least not in LV.

I've finally gotten around to doing this test, and for the most part none of the four properties trigger with automatic exposure changes.  The only exception is PROP_APERTURE2 for the few seconds following a half-shutter press in P and Tv modes.  As you suggested, I put printouts right at the top of each of the properties, and they respond as expected to changes that are manually applied.

None of this is off topic. So I guess you're right. It's "of " topic, being on topic about exposure on the 50D. Unless you think a forum about 50D specific video exposure should not be included within a topic on the Canon 50D, I'd say we're doing pretty well. Gotta love spell-check, right? "Pleas" use it.

Hey A1ex,
If you don't have coding skills, show me a video with the exact differences between the two builds (I don't have a 50D).

If you have coding skills, let me know how the exposure-related properties react in 50D when Canon decides to adjust the exposure automatically, e.g. when moving from inside to outside (test code linked above; a video showing the reaction of these properties would be perfect).

FYI, the 50D's video mode is similar to the one from the old 5D2, that is, without manual exposure controls. Therefore, ML adds them via exposure override (and, of course, should not sync to Canon's auto-exposure code).

I don't have Magic Lantern coding skills unfortunately. But I can verify that Canon was not altering the exposure settings. My camera was set to 1/50 on manual mode where it remained for photographs. ML seemed to give me odd shutter speeds and 180 equivalents, which changed when I attempted to adjust my aperture, throwing me into a "two steps aperture, two steps back shutter speed" mindset. Depending on the light I am experiencing when I activate Live View, this "Live view specific" shutter speed is different every time, causing me to reset all of my settings frequently.

All of this is  without Exposure Override activated. With Exposure Override activated, I am able to manually set my exposure. This is on the most recent nightly build, I have not tested other nightly builds.

I made a video of this occurrence here, though I'm sure this ML build was coded and written in this way for a reason that I don't understand or know of quite yet.


I'm currently using the Stable v2.3 build with the June 11 GregoryOfManhatten build (http://www.magiclantern.fm/forum/index.php?topic=5586.0) instead of the most recent nightly build and am finding great success with the simple and easy exposure settings (with the exposure override setting activated. Due to the inconsistency of the nightly build, my "build" seems to be much more simple.)

Thank you for your help in better understanding my camera and magic lantern. You guys totally rock.

@ImagineFlight: with exposure override turned off, you do not have manual exposure controls. You have Exposure Simulation. That is, you only get some brightness equivalent to the exposure settings you have dialed.

Proof: adjust the aperture and listen to lens clicks. There will be none. Instead, ExpSim is keeping shutter speed at around 1/60-1/100 and it's bumping the ISO. To confirm, take some silent pictures at different apertures and check the bokeh and the noise.

@ayshih (and anyone else who can compile ML): at first sight, it seems that CONFIG_NO_MANUAL_EXPOSURE_MOVIE should be disabled for 50D (internals.h). If the properties do not react in movie mode when you move the camera from bright to dark (like they do on 500D), disabling this will allow expo override to sync with the exposure values from properties (as dialed from the scrollwheels). Can you confirm?

Hey @A1ex, Thank you for your help - I am in better understanding now. I think I'll continue to use my own v2.3 build since it's always worked for me. I like the new look of the nightly build with its shiny font and built in RAW, but the manual controls aren't as basic and controlled as the old build. I'll try out the future nightly builds to see if this changes, but for now I'll stick to what I know.

I'm interested in learning more about the coding behind ML, if you could redirect me to a forum explaining how to program ML, maybe I could contribute a little bit to what you're looking for.

Nightly Build 14 May 2014 Notes:

Live View - Expo Override DEACTIVATED:
-------------------------------------------------
+Shutter speed does not match camera settings
+Top shutter wheel adjusts ISO values, not shutter speeds.
+As shutter wheel is spun, adjustments are made in the opposite direction. I.E. a spin to the right decreases ISO values

@A1ex, you must be a mad scientist. This build is as simple and usable as my (Stable v2.3 + raw) build, but with the benefits of the previous nightly build. I'm going to zip this build together and keep it in a warm happy place on my backup hard drive.

I'm also looking to get into using the new MLV format. I understand that tagging is available. A couple questions:
+Is changing from Raw v1.0 to MLV worth the different workflow, as the 50D does not record internal audio?
+Tagging the Take# is functional on the 50D on your new nightly build as well as the previous, but TEXT TAGGING is not functional in either build. Tips? Not possible on 50D?
+Using MLV2DNG.exe and MLVViewSharp, All frames are pink.

Keep on rockin,
ImagineFlight

Hey guys. I bought a used 50d so I could play around with RAW video (my SL1 doesn't have ML available). I've got RAW video working and it looks great (latest nightly)...

My question is, where in the menu do you change the frame size/aspect ratio? I was hoping to play around with wide-screen stuff, and also just shoot at 720p. The default setting looks great but I'm wondering if I can change it in the menu somewhere and being a noob just can't find it.

thanks,
Justin

Just hit the function button to locate additional sub options for everything within ML. In your case, scroll over the RAW option, and press function. Press function again to exit the submenu, or hit the live view or trash can to exit back to live view again.

Try deleting your ML files on the card and replacing all files with the latest build. I'm not sure what you mean by "disable BLACK LEVEL."

Also - I get pink frames when I use the MLV format on my 50D. I recommend using the other raw option (which may be what you're doing already if you mean .RAW mode, good luck)

I just want to ask something. Is anyone else having overheating problems? After 30 minutes with the LiveView turned on, i start  having the ML message FPS Warning. Possible overheating. And the Termometer that comes in the Global Draw is at 57ºC. My only workaround is to turn off live view whenever i can. I have read in the ML manual that 50D may overheat. But in other people experiences it doesnt get heated so quickly so maybe im doing something wrong. ¿Anyone with the same problem? ¿Solutions? Maybe any bad configuration i may have?

Heh, I was wondering just yesterday whether that particular code still gets triggered; apparently the answer is yes!  The "FPS Warning" is because the recording gets locked to 22 fps, irrespective of the desired FPS.

I think you'll find that overheating is a common problem for anyone using the 50D for recording, especially if you're talking 30 minutes.  For example, earlier in this thread, sync24fps had come to the conclusion (http://www.magiclantern.fm/forum/index.php?topic=9852.msg112462#msg112462) that, under his circumstances, he could only record for a few minutes at a time before encountering issues.

@ayshih thanks for pointing me in that direction. I did some searches and didn't find anything. The tips that this man gives are great. I already have the battery grip and i will try using an external monitor to see if it overheats less.
In fact, i had some problems with corrupted files . Luckily i could rescue them (almost) all with this python script.

http://magiclantern.fm/forum/index.php?topic=8237.msg115455#msg115455 (http://magiclantern.fm/forum/index.php?topic=8237.msg115455#msg115455)

I thought it was caused by the card getting full but now i think it was caused by overheating and full card (Lexar 32GB 1000x (just 9 minutes of video  :'()).
After that corrupted files problem i tried to keep the camera cool by shutting off the live view while i wasn't using it and after every shot. The settings keep the same doing this and the temperature goes down some degrees.

Hello all, I`ve been combing over any information I can find on 50D RAW via the ML forums. The way the community tests and forges new builds seems quite exciting! I just spotted a 50D at my local camera store for $275 and I feel quite tempted to jump into the world of 50D RAW.

My only reservations are those that relate to the camera overheating and dropping frames.

What sort of continuous record times is the 50D currently getting with the fastest cards?

Thanks!

The 50D is a better performer in low light for RAW capture than the 5D MKii and 7D!  At only 25% less resolution than the 5D mkii, its surly worth the price to pick one up. 

I am experiencing iso noise that is sooooo bad I'm afaid to shoot anything higher than 320. Can someone tell me is everyone just removing it in post? Or am I the only one who feels this way? I have used the t3i for the last two years, and I'm comfortable shooting all the way up to 1250, but 400 on the 50D looks worse than 1600 on the 600D. (to me) am I spoiled? Should I just treat it like a slow film stock and avoid high iso's or is there post magic that makes the higher iso's acceptable?

Make sure your exposure is manual and that you're getting an even exposure for each frame. You won't experience any noise, just trust the camera. If your exposure is too low or too high, you'll get that noise. If you need more light and want to keep your shutter speed (which you should always keep) and aperture is already wide open, then ramp it up in the ISO until your bracketing reads as close to 0 as you can.

For a camera such as the 50D, your lens speed is directly related to the quality of shots in low light. A fast (say 1.7) lens will give you more light. And if the lens is made for m43 (APS-C) sensors,  you'll also improve your images in low light because the sensor will be collecting more light. Both of these features translate into using lower ISO settings. Low ISO = lower noise. Couple that with some fair amount of lighting and you have a decent low-light camera - it's not a 5DMIII. So keep that in mind when using the 50D.

Also if you compare the noise of the 400 iso 50d raw vs the 600d's 1600 in h.264, your not comparing the same kind of image. H.264 is mud compared to raw footage

Low ISO = lower noise.

Compare ISO 100 1/100 f/4 with ISO 800 1/100 f4, both graded to look the same. Which one is noisier? Post the results.

(of course, you can choose other shutter and aperture values, just keep them the same in both images)

I can't seem to access the nightly builds right now, but the dates displayed on the webpage are adjusted for your time zone.  The "May22" build has a build date of May 21 in US time zones, so the build you saw probably did have mlv_play in it.

Here is a screengrab to show what I am describing:
(http://www.dpvisualmedia.com/wp-content/uploads/2014/05/noise-2.png)

This is shot at f2.0 1250 ISO (1600 pulled down to 1250 with ML-3)
shutter speed is 50, FPS is 23.97

Now this is a scene lit only by a 100w table lamp, but at these settings I can get a great exposure with reasonable level of noise on 600D, is there something wrong with my 50D's sensor? Or is this normal? It looks fine with adequate light, but in low light the noise is unbearable....

BTW, does RAW Video benefit from the iso's pulled down?

Am I just not used to seeing this noise because H.265 clips the shadows and applied a picture profile? Or is this an unusual amount of noise? I really don't know what to expect because I have no experience with this sensor... I see small black blotches that come and go and a strange criss-cross pattern of vertical and horizontal banding. It looks like a defective sensor to me..

Post two silent pictures, one from 50D, one from 600D, showing the same scene, with the same lens and same exposure settings.

Include a screenshot with the settings (the LiveView screen), because the silent pictures don't include exposure metadata.

Yes, exposure wise (so overall brightness in the output files should be equal). So, the ISO 800 one should be darkened by 3 stops (from the exposure slider), compared to the ISO 100 one.

I just got very good results by exporting dng from mlviewer and importing as camera raw sequence into adobe after effects. I adjusted the white balance and crushed the blacks a little bit then exported lossless avi. Can someone please tell me if SRGB is the correct setting for mlrawviewer for this process? Or should I used rec.709, I couldn't find a clear answer on this.

Hi Guys im new here and thought i would say hi,

i put ML on my camera last night but was overly impressed with what i gained. Today i had a search about and found this thread so i downloaded the nightly build Built on: 2014-05-24 01:48:50 +0100.

I much prefer this layout and found it easier to see what i wanted to do.

I have a couple of questions about it however.

when i go into the info menu and try to open any of the functions such as press FUNC i get a message no info found ? did i miss something out?

secondly i like the menu that opens when you push the joystick in but i hate it on that button can i move it?

third as i use the joystick to toggle my focus points it seems a waste to also have the SET button doing this function as well as acting as a half press to re focus, i don't want that can i stop it.

i managed to turn off the SET button in the original ML 2.3 build but i like this one better.

cheers

Hey guys, so I'm trying to make the jump to MLV to save myself having to adjust WB on each clip like in RAW, but I found that the "fix black level" option does nothing but create pink DNGs that even ACR has trouble reading properly. It seems like a dangerous design flaw to have that option automatically be enabled in mlv_rec. Can we make it harder to reach or simply remove it? I'm hesitant to use MLV now because I'm scared I'll accidentally turn it on or maybe after a bad reboot the camera will turn it on, and unlike some bad settings that can be easily dealt with, gross pink DNGs even in ACR doesn't seem like an easy fix. Thanks.

After that the camera starts freezing again and again, even if im nit recording. So i just shoot raw. But it would be nice to have a better mlv mode :)

Hi,

I am a proud owner of a "new" 50D and I tried ML Unified 2.3 (stable). Installation was flawless and video recording was working.
However, only 1080p30 in H.264 and some lower resolution was available, but that seems to be a limitation for my camera? I found no information in the dokumentation of ML Unified regarding the available resolutions on a 50D.

For raw recording, I think I need the raw_rec or mlv_rec module (and new autoexec?) since no raw option is available in Unified 2.3 - but do I need to compile the module itself or is there an existing module for 50D? Perhaps even included in the newest nightly builds I can download at http://builds.magiclantern.fm ?

Another thing I missed is the card benchmark; I can't find it in the menu. Is this a custom module also?

Download latest nightly build if you want to use MLV/RAW.
Format card inside your cardreader, insert it to cam. Format it there a second time, copy expanded contents to card (cardreader again), startup cam and run firmware upgrade.

Very impressed with the latest nightlys, haven't had any stability issues whatsoever. The work the devs are doing is amazing.

One thing that I've noticed is that when using the RAW module I am able to record 24p 1920*1080 for around 1200 frames before it starts skipping. Using the MLV module with the same settings however only lets me get about 200 frames. Due to the fact that the 50D can't record audio there's not really any reason for me to use MLV anyway but I'm just wondering what causes it to perform so much worse for me.
Title: Re: Canon 50D
Post by: handbanana on May 29, 2014, 12:29:36 AM
I get similar performance drops with MLV, but the benefit for the 50D would be the WB metadata if you know you're nailing it in-camera, so you can skip the WB settings in post.

The 128gb 1050x works great for me. I can easily get continuous 1:1 no crop or 1920*800 and can record 1920*1080 for 1200 frames (50 seconds). Here is the benchmark, bear in mind the cards benefit a lot from being warmed up first.

Cool, thanks! I ended up getting (2) 64GB 1066x to complement my (2) 64GB 1000x cards. Gonna use the 1066x on a Mk3 today for a short film (and the 50D with the 1000x). :D

Hi Guys,

I've just install ML on my 50d.
Something wrong is happening: the card led blinks constantly when the camera is powered off, I have to take out the battery in order to stop (but if I put the battery, the led starts to blink again).
I've tried with other card and same problem.
On the last try, I installed the last nightly build and the problem doesn't disappeared.

Could you help me, please???

More details needed:

- number, frequency and color of the blinks (a video is even better)
- if you start ML with default settings (from a freshly prepared card) and shut it down, does it turn off properly?
- if you start ML by holding the SET button at startup (ML loaded, but inactive), and shut it down, does it turn off properly?
- if the last two answers were "yes", you can start enabling your usual settings and narrow down (figure out which setting causes the problem)

Hi A1ex, thank for your support!
Actually, it's a red light and blinks each second (aprox).
If I start ML with default settings (from a freshly prepared card) and shut it down, the camera doesn't turn off properly, same problem. And I tried with different cards.
I did the test, and start ML holding SET. Shut it down and the problem continues...

Thx

I got problem with ISO and shutter setting, it doesn't change actually (there's no difference on the LV when i set another vaule of iso or shutter). Whats wrong? Maybe sth in the canon software is set not right or something. ISO is setting automacily even when i set the value myself.

So let say if I get a fast enough 128GB CF card the 50D can shot RAW video continuously until card full? (like 45-60min?)
Does anyone try something like this before, shooting long RAW video on 50D, and can obtain audio sync in post? (I understand that 50D doesn't have audio, but in post processing if I sync it at the beginning, would it continue to be sync by the end? In the past I have sync issues with my GH1 and an external recorder because the GH1 do not have a fps exactly 23.976 but slightly slower.)
And are there overheat problem that will stop the video unexpectedly?
Thanks!

Post by: dlrpgmsvc on June 27, 2014, 02:43:03 PM
@kolen: with the latest tragic build it is technically possible to fullfill any card size with continuous raw video. On the other hand, so much time you indicated brings so much heat buildup  that record will stop. Also, battery  cannot last so much time in raw mode, even with a battery grip. For these reasons, no one so far tried to see if there would be audio sync problems  for so much recording time.

Post by: LEVISDAVIS on June 28, 2014, 02:38:00 AM
@Kolen -- The timers with Canon are probably right on. No problem. if you have to go into the 64 to 128 GB range there shouldn't be any issues. It's @ThomasWorth every RawMagic moment!
Title: Re: Canon 50D
Post by: dlrpgmsvc on June 28, 2014, 12:32:01 PM
Yes, there is also a 12min time limit that is not overridable by ml. You can only set to resume automatically the recording after each 12min time chunk, but you will lose some recording seconds. So, definitely: if you need very long continuous recording, head for a more classical video-camera...

Thanks so much for the magic lantern firmware.

I just would like to ask a question, what settings do you guys use for best quality of your raw video?

My Gear: 
Canon 50D and
Lens Tokina AT-X PRO SD 11-16 F2.8  (IF) DX II
CF card Komputer Bay 32GB 1000x 
Mac Pro 2012 3.2ghz Quad Core 8gb ram Radeon HD 5770 1gb
Workflow: Convert from RAW to DNG with RAwtoDNG then Color correct with Davinci resolve then send those videos (Prores 422 HQ 1920 x 1080) to FCPX and edit and then i send project to compressor to upload to youtube (all best quality possible)

my main porpoise is to shoot video inside of condos and houses for sale and rent and upload them to youtube in the best possible resolution, also i take ouside videos of the pool and gardens of the house. So i want the videos to look crisp and clean, not so much to add special effects. (no matter how long it takes to process or upload)

MOVIE:

Fps Override
Desired FPS: 23.976
Optimized for: Low light
Actual FPS: 23.988
Constant Expo: OFF
Sync with shutter OFF


Image Fine tuning: 
ML Digital ISO: -0.3 EV
Black level: 0
Absolute Zero sharpness: ON
Edge Emphasis: ON
Noise reduction: OFF

Raw Video:
Resolution 1568 x 882 (thats the max it allows me)
Ratio: 16:9
Card warm up : 64mb


SHUTTER SPEED : 1/50  176*
Expo override: ON

Any pointers would be really appreciated THANKS SO MUCH, ill be a great idea of unifying all this ideas and pin in the forum for other people to use those same settings.

Yes. In reality it is a 4gb limit, that using h264 is reached in 12mins. Raw does not have this limitation but there is a 30min timeout hardcoded into the canera that shuts down the lcd screen and so it stops raw recording. No ML overrideable. However, at any decent resolution, recording raw will fill up any nowadays most biggest cf cards far before reaching the 30mins limit...

I'm about to buy a 50D and a Komputerbay 128GB for shooting RAW videos.
Any problems using 128GB CF cards?

And I think about getting the 1050x CF card version. matthiasdeo posted (one month ago in this thread), he can record continuous 1920*800 by using the 1050x !

But how is that possible? Document says, 50Ds maximal write speed is 70MB/s. Also the document says max resolution for continous rec is 1584x1058.
I'm talkin about this ML document:
https://docs.google.com/spreadsheet/ccc?key=0AgQ2MOkAZTFHdFFIcFp1d0R5TzVPTVJXOEVyUndteGc#gid=5

RAW video in those resolutions need something around 4GB space per minute, is that right?

Unless you are doing Raw Timelapse, then this 30 min restriction is a pain.  This is the reason I bought a BMPCC to go with the 50D, longest I've done with the BMPCC is just short of 5 hours with an external battery before the 64GB card was full (but the 50D with ML would be a lot better in a few situations like low light without this limit).

Of course, this 30 min restriction is Canon's, or the EU's, fault (different V.A.T. tariffs for video cameras than stills that can do under 30 mins video) - not Magic Lantern's

Thanks for the information. I don't know the 30min timeout hard coded before.
I was thinking 1584x662 recorded in 128GB card should gives me 52min. But I have to think again.
Actually 1584X891 will still give me 38.6min.
However before I am more "informed" I purchased one last Thursday and should be arriving today. I am most interested in how long it can continuously record (I have purchased a grip and plan to put two batteries there for maximum capacity). If all works may be I will use it in my next wedding shot (it's a proposal shot and they want to include the whole thing. I also don't know how long would they take). And of course with a backup non raw video camera.

So can now somebody tell me what CF card should I get for raw video?

I use the RAW_REC and test the continuous record and it crash at 12GB when it creates the 4th spanned file. The problem is, I cannot convert the DNG from it using both RAW2DNG and RAWMagic. How to due with corrupted files?
Should I use RAW_REC or MLV_REC?

So before I spend 10 bucks on a cheap card just for installing, I would get another smaller Komputerbay card.
32GB? 64GB?

I also heard the 1050x 64GB Komputerbay card is faster then the 1050x 128GB Komputerbay card, is that true? Because it says the same write speed...

And does the 50D now have a playback module for playing back raw videos?

Thanks for all the help! :)

I *think* the biggest is 64GB, but I would check this as it's been a while since I had to do this.

If the 1050x Komputerbay cards are the same as the 1000x ones then the 64GB is faster, but again might be best to check the other forums to confirm this as I've not used the newer card.

I use my 2GB card for trying out latest ML versions so it does get some use though, as well as some pictures sometimes - so it's not a total waste.

Hey, my bad. I was not writing clearly enough.

I am able to take 1920X1080 movie, but it can only sustain for at most about 20s in different ways I tried. Both RAW_REC and MLV_REC, and also all the buffer methods.
I am thinking if the card is too slow. Since I heard reports saying 1050x actually is faster than 1066x as far as Canon 5D Mark III is concerned. And I think I heard people can get 1920X1080 from 1000x, I might be wrong though.
Title: Re: Canon 50D
Post by: kolen on July 02, 2014, 01:37:44 PM
I tried in full sensor mode for continuous record and RAW_REC can record until card full, which is about 24:40 for 64GB at 1568X656
MLV_REC however consistently gives me problem and often crash. When it can go continuous, It usually crash at 5:40.

fps override?
Title: Re: Canon 50D
Post by: kolen on July 03, 2014, 02:46:23 AM
I override it to 23.976 and exact. Is there some limitation on fps override in crop mode? I googled and find people saying in crop mode I shouldn't be using exact. I tried the low jello and 180d option, it gives me 44s of 1920X1080 video in crop mode (Lexar 64GB, 1066X). I did it again and find out it stops when it starts the 2nd file span. So the first file is 4GB and the next 3xxMB and stops. I think may be it's just the card is too slow. Is it?
Many thanks!

Edit: I followed this blog: http://altcinema.wordpress.com/2014/05/10/magic-lantern-setup-settings-and-shooting-raw-hd-on-the-50d-2/ , which in itself is following by a suggestion in MagicLantern, to format the card in a specific way. I can now get about 2 MB/s more. But sustainable 1920X1080 is still not possible. After the first spanned files it stops at 65s (in using the low jello option). But I can get sustainable video in crop at 1920 width with 1.85:1 aspect ratio with 23.976fps and low jello. This allows me to record until card full.

I would be careful before ordering the 128 GB card. There has been a lot of reports on bad speeds on these. Make sure you read at least some of the threads that discuss this before you order. I went for two 64 GB cards just to be safe.

@kolen: with the latest tragic build it is technically possible to fullfill any card size with continuous raw video. On the other hand, so much time you indicated brings so much heat buildup  that record will stop. Also, battery  cannot last so much time in raw mode, even with a battery grip. For these reasons, no one so far tried to see if there would be audio sync problems  for so much recording time.
Since I bought one I tried it today about battery life and found out one single Canon battery will gives me about 71 minutes of recording time. The settings is in a Full sensor mode with 2.39:1 ratio at 23.976 fps exact.
Since I only have 64GB Lexar 1066x card the card will be full when 24:40 min of videos has taken. I restarted it each time until battery dies.
What I am planning to do is to get a 128GB Komputerbay card and see if I can get continuous 49:20 min of videos. I have seen the camera becomes too hot and have a warning signal. But only after prolonged usage. And let's see the upper limit of continuous video it can do.

I almost forgot about what you've said. I just tried to record a RAW Video at low resolution and it stops at 29:48. So there's indeed a 30min timeout. Do you know if the 30 min count down started from the moment I record movie or the moment I started liveview? Are there anyway I can do (e.g. go into the menu while recording) to fool the camera to reset the 30 min timeout during movie recording?
Thanks.

I've just done a quick test, normal timelapse but at 25 mins flicked the menu button.

F*ck me!!

My battery wasn't fully charged but the 50D stopped at about 38.46 mins when it ran out of juce - so it's definitely recorded longer than normal!!

Fantastic idea, i wonder if the Devs can just blip the menu display just before 30 mins to make it continuous without touching the camera?

Post by: kolen on July 04, 2014, 10:00:36 PM
Thanks all!

I was testing the idea last night but sadly it crashes and then I tried it again and it is overheated. So I decided to sleep first and test it again today.
But good to know someone else has done it already and it works!

One question:
Taking longer video make it more likely to have crash somewhere in between. I have occasionally crashed some clip. And I am not able to extract the DNG from it. I think the problem is the end of file. I tried to merge all the spanned files by CAT in terminal but it still doesn't work. No converters will recognize it (and I tried all listed in Magic Lantern Wiki, RAW Video page).
I find a site: http://www.conorcunningham.net/blog/2014/4/10/magic-lantern-missing-end-of-file
But its solution is rather technical.
Have anyone experience crashed videos (crashes in the middle of recording) and successfully extract them?
Thanks.

Edit:
here's another question: are there anyway to put the 30 min timer on screen so that we can quickly test which operations would reset the timer? I am thinking may be even if we press the ISO button (but not changing it) would do it too.
I just recorded a RAW Video longer than 30 min (up to 80 min and more and the sensor starts overheated and I stopped it). Since I don't know which button would do it, I pressed the Magic Lantern Menu button (trash), the ISO, and also the White Balance. From my testing, pressing the Canon Menu button or the playback button would stop the recording.
Edit:
I find that pressing ISO button alone can make the video surpass 30 min. I guess actually the 30 min. limit came from the sleep mode, since the longest time we can set for sleep is 30 min. As long as I press something it won't sleep.

Bug Report:
I find that consistently in 10x mode it will crashes very soon (~dozens of seconds). I am using the latest nightly build from July 2nd.

Hope that you don't mind me repeating the question: does anyone know how to extract DNG from a corrupted ML RAW file (due to, e.g., crash during record, battery drained, card full, etc.)
Title: Repairing damaged header / footer
Post by: LEVISDAVIS on July 12, 2014, 09:54:44 PM
... All of the DNGs are inside the wrapped MLV or RAW file... It will take a hex editor to replace the missing information in order to extract the DNG images. Once completing the hex editor footer replacement you'll be ready to process the original MLV or RAW file on your regular DNG extractor application.

Take a look back at page 3 of the 50D topic... There are a couple of entries that I wrote explaining the process of fixing damaged footers.

My 50D was delivered today. I had much fun getting my 64GB 1050x Komputerbay card running (my antivir doesn't let me download EOScard tool) - but OK it's running now.
My first questions:

-I'm in RAW movie mode, 1568x882. sometimes it says:
55.3mbs at 24.001p. Expect around 0 frames at 46.4mb/s
and sometimes it says:
55.3mb/s at 24.001p. continous recording ok.

So why do I get different results every time I do into the menu? And is my card really to slow? I mean it's the 1050x 64GB, that should be fast...

-other question: I think I read somewhere that you can record short raw videos in FULL HD resolution, it just stops after few seconds. But everytime I wanna change to somewhere over 1568x882, it says for example:
1920 is not possible in current video mode (max 1568).
So how can I record short raw video files with a higher resolution?

-And, by the way, what is better for the EOS 50D - RAW or MLV ?

Hope somebody can help me...thanks!  :)
Title: Re: Canon 50D
Post by: dsManning on July 17, 2014, 12:46:22 AM
The expected results are based on your last recording speed (I think). Don't pay too much attention to them.

For 1920 recording, use the button on the top right of your camera to go into 5x crop in LiveView. Once you are in that video mode, 1920 resolutions are available to record at. With my 1000x and 1066x cards, I can record continuous 2.35.1 ratio at 1920.

One of the main selling points of .mlv over .raw is sound recording. The 50D has no sound input. However the metadata stored with each frame in .mlv is a very nice improvement over .raw

It might be because the card speed varies quite a lot. So it used the last write speed to help you to determine if you can record at a certain setting continuously or not. But since the speed varies, from time to time you might get a different suggestion from the manual.
Also try setting the fps to exact. It would be better if you use multicam (so that they share the same 23.976).

I don't know if it is just me or not (I am a newbie and bought a 50D a month earlier than you), but the MLV_REC seems more unstable than the RAW_REC for me at least. For MLV_REC the 50D crashed at about 5:40 of recording but for the RAW_REC I can get up to 80 min. (and ends because of overheat, not crashing).

Try the latest nightly with SRM memory. You should get a lot more frames. Even my slowest card (Transcend 600x) can record continuous 1568x882 and about 17 seconds at full HD (crop).

Use MLV_REC. Make sure to set picture size to raw and no jpeg (-) in the Canon menu. Switch off global draw in the mlv module and leave 'Fix Black Level' OFF (not needed). Disable the functions you don't need (i.e. don't enable vectorscope etc if you don't need it).

@Kolen - 80 mins?  ??? How big is your card?

@Kolen - 80 mins?  ??? How big is your card?

In the past people suggests choosing smallest JPEG but not RAW in the Canon menu. Does the newest nightly change it?

For the newest nightly (magiclantern-Nightly.2014Jul17.50D109) it seems in crop mode it gives me occasional pink frames but I am checking if it is the card issue or newest nightly issue.

I tried recording at the lowest possible settings, so it stress on the Live View and the stability of the software, and overheat but not including a huge write speed, in that case I got 80 min.
Yesterday night I tried recording at 1982X992 which is at about 80MB/s and the card heated up the sensor much quicker. But I can still record RAW video untill card full on 128GB 1050X Komputerbay, which just over 24 minutes. By the end of the recording though, there's a warning saying something like "FPS warning, overheat", etc. (wait, now I start worrying if I overheated the sensor too much so that it gives me pink frame even when it's cooled down?)

Edit: I just finished recording a video of 1568X656, full sensor 2.39:1, to fill the whole card of 128GB Komputerbay 1050X. The total duration is just below 50 min (by pressing ISO button to reset timer). And the sensor has overheat warning by the end of it.

Edit: I tried it on an older build and it doesn't seem to have the pink frame. However I only recorded a few minutes.
I guess it is the newest nightly that cause the issue. How do I report the bug (after I have more testing)?
Thanks.

Edit: I nailed down the builds that cause the pink frame problem:
Nightly.2014Jul17.50D109 and magiclantern-Nightly.2014Jul16.50D109 2nd build.
Using earlier build doesn't seem to have the same problem. e.g. magiclantern-Nightly.2014Jul16.50D109 1st build, magiclantern-Nightly.2014Jul15.50D109
The condition is, I use RAW_REC, Expo. Override, Global Draw off, FPS 23.976 exact, RAW Video at 1984X992 in crop mode. Shutter 179 degree, ISO 800, lens with no electronic contact, etc.
And the pink frame will show up quite frequently, and can be seen even in live view.
Title: Re: Canon 50D
Post by: LEVISDAVIS on July 18, 2014, 07:19:17 PM
07.18.2014 build produces pink frames in crop mode when shooting with RAW + JPEG photo mode enabled & RAW (only) photo mode enabled.

Whether shooting at 24FPS or 30FPS, .RAW, Global Draw turned On or Off, Raw HistoBar On or Off, and SRM On or Off.

Global Draw Turned Off - 24FPS - Crop Mode 1988 at 2:35 pink frames only on the first and last frames.

After experiencing a skipped frame, almost always on first record even with card-warmup enabled, ML takes about 10 seconds to re-enable camera functions. Camera acts frozen and no buttons should be touched.

Note:

** Shooting continuous 2.20:1 at 1984 is possible with a Komputerbay 128GB 1050X. 50D write speeds have increased significantly since last year.**



Processing Side Note / Discovery:


The noise floor is very organic and film-like; similar to the way DaVinci Resolve Lite processes DNG files.
Footage is "grade ready" despite not having highlight recovery.
The white balance looks spot on.
Another fast turn-a-round option like DaVinci, but with no grading potential outside proper white balance, for offline/online ProRes files.
(1405 frames or 1 minute of footage shot at 1984 2:34 upconverted to ProRes4444 @ 3072x1307 in less than 1'45" on a Macbook Pro 15 Retina with OpenCL.)


07.15.2014 build has no pink frames.

Wow. That was very quick.
I tried developed a 1568X656 @ 23.976 fps, in a total of 437 frames (18s). And importing to After Effects directly, with no other processing except changing the WB. It took my machine about 90s to process it. I have a GTX 660 with CUDA driver installed on a Mac.
Is it because my AE is too old? I'm using CS6. And what exactly do you mean "ACR is not utilized"?
Title: Re: Canon 50D
Post by: LEVISDAVIS on July 18, 2014, 10:01:45 PM
After Effects relies on Adobe Camera Raw (ACR) to process the DNG files.
Adobe Encoder 2014 and maybe Adobe Encoder CS6 bypasses ACR to process DNG files. The processing speeds are two completely different beasts.

Importing DNG image sequences directly into Adobe Encoder 2014 provides the ability to bypass Adobe Camera Raw and yet it still produces a usable image based on simple exposure, tint, and temperature adjustments (no highlight recovery or shadow compensation).

In other words ACR is not optimized for Cuda or Open CL. AE is always so slow at exporting footage. DaVinci has been capable of exporting the 1586x? at around 10 - 20 FPS using single node processing. AE is about 1 - 5 frames depending upon certain ACR settings. Anyway, by finding a way to convert DNG into MOV using Open CL or Cuda definitely produces quicker results.

Not sure if Adobe Encoder CS6 has the option for Open GL or Cuda optimization upon export or if it can even import DNG image sequences directly into the encoder?

The resolution choices were constrained to certain multiples on 2014 Mar 14 due to crashes on newer cameras.  For maximum code portability, and in case there were subtle issues not yet encountered on older cameras, this constraint was applied to all cameras.  See:

Not going to find any flickering using the Adobe Encoder 2014 "quick-processing" technique.

1045 DNG images at 1984x844. Files converted onto internal Macbook Pro SSD using RawMagic Lite. Adobe Encoder 2014 renders to UHD 3840x1634 ProRes Proxy in 56 seconds. Converting to ProRes HQ takes 1'14." It's a "grade-able" start point too if you process the footage in camera properly.

Direct Comparison to ACR reveals very poor aliasing, natural color calibration, great noise floor, and just enough dynamic range to really give it a good grade.

Seems like the concept of upscaling should be left in the hands of ACR.

Hey guys so a couple questions.

(1) How do I shoot at ISO 6400 or 12800? I set ISO to 6400 in camera and it says 6400 but it looks the same in-camera. RawMagic sees it as ISO 6400 in the metadata (.MLV) but then in Resolve it still looks the same as a clip shot in ISO 3200. And 12800 doesnt register in-camera. It does if I turn exposure override off but then the camera also does a bunch of crazy stuff.

(2) How well does Dual ISO work on the 50D and how would I go about processing the files on a Mac?
Title: Re: Canon 50D
Post by: djfremen on July 20, 2014, 12:14:16 AM
Forgive the ignorance if this has been answered but with the new developments with SRM, are we to consider this only affects record duration and not raster size? Will the 50D always be locked at 1500+ in normal, non zoomed mode or are we expecting full frame someday? Also, has any done a side by side comparison with the 50D with and without VAF?
Title: Re: Canon 50D

This is undoubtedly because ISOs 6400 and 12800 are not "real" ISOs (i.e., with different amplifier settings), but are digital manipulations of the raw data.  RAW recording skips such manipulation.

(2) How well does Dual ISO work on the 50D and how would I go about processing the files on a Mac?
Dual ISO photos work fine.  One way to process files on a Mac, at least if you use Lightroom, is to use this plugin:

The SRM improvements give more memory, but the current maximum resolution for RAW recording is a consequence of using the LV feed.  There may be some hope in the future with the recent discovery of full-resolution silent pictures (http://www.magiclantern.fm/forum/index.php?topic=12523.0), but much more investigation needs to be done.

I override it to 23.976 and exact. Is there some limitation on fps override in crop mode? I googled and find people saying in crop mode I shouldn't be using exact. I tried the low jello and 180d option, it gives me 44s of 1920X1080 video in crop mode (Lexar 64GB, 1066X). I did it again and find out it stops when it starts the 2nd file span. So the first file is 4GB and the next 3xxMB and stops. I think may be it's just the card is too slow. Is it?
Many thanks!

Edit: I followed this blog: http://altcinema.wordpress.com/2014/05/10/magic-lantern-setup-settings-and-shooting-raw-hd-on-the-50d-2/ , which in itself is following by a suggestion in MagicLantern, to format the card in a specific way. I can now get about 2 MB/s more. But sustainable 1920X1080 is still not possible. After the first spanned files it stops at 65s (in using the low jello option). But I can get sustainable video in crop at 1920 width with 1.85:1 aspect ratio with 23.976fps and low jello. This allows me to record until card full.

Hey Koren,

I wrote the above blog, but hadn't yet updated some of the recommended settings, including to use RAW + no jpeg. I finally just did so.

I think you already figured this out, but for everyone else, supposedly these are the recommended Canon menu settings (please advise anyone if this is out of date):

Image Quality = Raw
Auto Lighting Optimizer = OFF
Long exp. noise reduction = OFF
High ISO speed NR = OFF
Highlight tone priority = OFF
Multiple Exposure = Disable
HDR Mode = Disable HDR

Title: Re: Canon 50D
Post by: ayshih on July 22, 2014, 12:23:28 AM
It's a possibility, but definitely not "soon", and not without some more breakthroughs.  From the relevant thread:

Limitations

- The fastest shutter speed I've got is around 1/10 seconds (very rough estimation by comparing brightness from a regular picture). With regular pictures, faster speeds are done via mechanical shutter actuation.
- Long exposures are fine up to 15 seconds (longer exposures will crash the camera).
- Fastest capture speed: 220ms on 5D3, 320ms on 5D2. This includes a dummy readout, which is probably a bias frame.
- So, at least for now, the usefulness is limited to timelapse and medium-long exposures (no moving subjects).
...
4K video?

Too early to ask. Find a way to speed up the capture process first (see the research section below).

However, I don't really expect more than 10 fps (in LV crop mode on 5D3, 1/3.6 of the total sensor area is sampled at 30fps). If you implement a burst mode from the current code base, you'll get up to 5 fps.
...
Research
...
- figure out how to speed up the capture process (maybe without the dummy capture step, or find out how to trigger the continuous readout mode)
- figure out how to get fast shutter speeds, as in LiveView (electronic shutter)

Looks really sharp and detailed! But I think you should spend some more time on color correction. Also, I would definitly use a stabilizer system for shots like this. You can get them for less than $100 on eBay, Amazon, or asian websites...

Thanks.
This videos im making are not for the people of vimeo and movie gurus etc, this videos are more for people that want to go to the beach and see a happy colours and vibrancy, thats what im trying to achieve. this is what i would like my videos to look like http://www.flykam.com.au/real-estate-videos-tours/2-tully-court-kuranda-vanessa-robinson-lj-hooker/  if you have any suggestions in how to achieve those looks its greatly appreciated. all the corrections im doing are in resolve and im new at it.

The stabiliser i use its the steady tracker ultra lite i know is not the best but it fits my wallet,and its extremely easy so set and use, i know how to use it better now, this video its really old, i never got around editing it.  i wanna get the CAME 7500 gimbal, which its amazing but cost 1,200 USD. so still waiting to have the money.
Workflow its convert the RAW/MLV with MLRAWVIEWR (is raw magic better or another software better, i use mac pro) then use those files directly in resolve. i don't apply any LUTS since some colourist in blackmagic design forum says that it degrees the quality of the footage. (i was using the EOSHD 5dmark 3 LUT before) i did all the edit in resolve and transitions and text etc.
I did sharpening by separating luma and chroma (black and white and color) and sharpening a lil but the black and white and in the color node get rid of some noise with the opposite of sharpening tool.
my timeline was done in 1920 x 1080 and then the output was crop to 1920 x 804 with h264 codec in the highest setting and it gave me a file of 990mb. sound was on AAC.

And LUTs...I heard (and see) the OSIRIS LUTs by VisionColor are really good. Maybe you should check them out.

This videos im making are not for the people of vimeo and movie gurus etc, this videos are more for people that want to go to the beach and see a happy colours and vibrancy, thats what im trying to achieve. this is what i would like my videos to look like http://www.flykam.com.au/real-estate-videos-tours/2-tully-court-kuranda-vanessa-robinson-lj-hooker/  if you have any suggestions in how to achieve those looks its greatly appreciated. all the corrections im doing are in resolve and im new at it.

Looks good to me! :)

Hopefully someone can keep me up to speed. I've been away for a year now with my ML. I'd like to update my ML again. Is it still the same process, copy the ML firmware into our sd card, put it on our camera, boot it and install new ML firmware?

Also, which compact flash card would you recommend if I wanted to do raw recording?

I forgot, where can we download the latest stable firmware?

Thanks!

Hi everyone.
I wonder what the latest is regarding using 50d with a field monitor when recording raw.

1. Does it work with both hdmi and avi (if that's the name for analog)?
2. Does it show overlay?
3. Does it impact performance?
4. What is the output resolution? The same as you film, 1080p/I or something else?
5. Is there anything else important to know about field monitors and 50d?

If you use one, which one and how?

Thanks!

Hi. I've got a problem. When I record MLV with FPS override set to 23.976 exact (Nightly.2014Aug02) I get these intervals between frames (ms):
35   35   35   50   43   52   18   47   40   53   35   52   35   53   35   35   40   45   35   42   38   60   35   45

This is according to a video where I recorded a high-precision stopwatch from my LCD screen (60Hz). Can anyone suggest a more accurate procedure?
What could I be doing wrong? Any comments on this?

Post by: dmilligan on August 04, 2014, 06:21:48 PM
There are too many free variables. You need a control (http://en.wikipedia.org/wiki/Scientific_control). There's no way to tell if it's just the watch, the camera itself (boot without ML), or due to ML. You must design an experiment that eliminates all but one possibility.

If I understand you right, you're running a stopwatch program on a computer with a typical 60 Hz display.  That means, from frame to frame on the display itself, you'd expect to see a ~17 ms time difference between frames.  Even if you were to then record the display at 1000 fps, you would still only see a new frame every 1/60 of a second, and that new frame would have a displayed time ~17 ms after the preceding frame.

So, it's not clear anything is wrong from your data.  The ~33-ms gaps are when the recording misses one frame of the display, and the ~50-ms gaps are when the recording misses two frames (23.976 fps is ~42 ms per frame, while two 60-Hz frames take only ~33 ms).  The other timing inaccuracies are likely due to inaccuracies in the display of the stopwatch.  Unless this stopwatch program was designed to have high accuracy (rather than just high precision), OS-level graphical calls probably have variability and delays that are contributing.

It's neat to try to test the accuracy of the FPS timer, but you need a better setup.  If there aren't (cheap) real-world high-precision stopwatches with displays that have high refresh rates, you could instead build one (e.g., a microcontroller plus LED digits).  Alternatively, you could try a kookier setup that makes use of a spinning laser or the trace of an analog oscilloscope.

Is it possible to make an H.264 playback module on the 50D? For certain projects, using 3X bitrate is just much more practical than raw. Not being able to play back is a killer though.

I picked up a 50D on a lark and I am extremely impressed with what the ML developers have accomplished. I'm shocked by how beautiful the RAW footage looks and that it records to reasonably priced CF cards. I don't know if I'll ever wind up using it in a professional context but I will say that if I had explored this option sooner I would have seriously reconsidered some other purchases I made earlier this year. Big thanks to a1ex and the team for their really, really hard work. :)

I have a question though; I know that the maximum width of the 50Ds RAW recording had to be decreased from 1584 to 1568 for ML codebase portability concerns, but will this restriction ever be lifted? I know it only amounts to a 2.3% difference when you're recording 16:9, but I was just curious if we'd ever be able to squeeze that last drop of performance out of this camera.

Probably not, no.  It'll be hard to ever show conclusively that such resolution non-multiples that cause problems on some cameras do not cause any subtle problems on the 50D, and thus it's hard to justify the minor increase in area.

Totally understand. I'd rather have a stable camera than an extra percent or two of image area.

Completely off topic; does anyone else wonder where Magic Lantern goes from here? What is left to improve on the 50D besides stability, power use, etc.? I'm not saying that every avenue has been exhausted but does anyone know what the devs are working on at this point?

That's a great idea, if it could be done . . . . Play back at 30fps or even 24fps on the 50D would be icing on an already very delicious cake!

Hello,

I've been shooting raw with my Canon 50D since september 2013 and very happy with results.
On my last shoot, I had a pixel flickering on my shot.

I uploaded a small video file of the problem, along with the DNG and a still of the movie.
https://www.sendspace.com/file/niachs
Is it a problem with raw or on my camera's sensor?

Thanks!
Title: Re: Canon 50D
Post by: LEVISDAVIS on August 17, 2014, 09:11:39 AM
The flickering pixel relates to the sensor. Raw is clear enough to show just how much one pixel can affect the overall image. A good practice before shooting is to conduct a deep sensor cleaning, about 30 seconds to a minute will aid in "flickering pixels." Some times a 5-minute deep clean is needed to eliminate hot pixels. Though, hot pixels / stuck pixels tend to come back. But you'll find that almost all CMOS sensors have issues with stuck / hot pixels in some way shape or form. If stuck with the footage, I would find an image processor that automatically removes flickering / hot pixels when debayering the Raw images. Adobe Camera Raw automatically removes stuck / flickering pixels when debayering.

...Hope this helps you hone in on quality, usability, and also somewhat of the sensor industry's norm.

I read these 12 pages after those 180 and I know I did not read every word of these 12 but I'm bit confused .. I installed ML on my 50D but I don't see RAW video anywhere? Do I need to get the latest nightly or? Any ideas if the RAW feature for 50D will go to stable release any time soon? How stable are the nightly's? I don't mind if camera crash from time to time but I'd hate to brick it (it's the only decent camera I have)

also some other questions ..

I remember in the 50D manual there was talk about "you cannot leave LV on for long because sensor will overheat" - I see temp during RAW recording (nightly) goes to 50C fast how safe is that?

what is the difference between modules that record MLC and RAW wrt 50D, I see that MLC adds some meta data and RAW is just raw but anything related to 50D I should know of? some use more ram then the other? some need more io then th eother?

and final question, can't find the "crop" option anywhere :(

You need to load either the mlv_rec or raw_rec module, and then enable one (not both) under the Movie tab.

There currently isn't a timeline for the next stable release.  The nightly builds are pretty stable, but there will occasionally be broken builds (hopefully fixed soon after).  I don't believe there's been an actual instance of ML bricking a camera in a permanent sense, but rarely a camera may end up in an odd state and need to be coaxed back to normal, which could mean days/weeks of downtime.

I remember in the 50D manual there was talk about "you cannot leave LV on for long because sensor will overheat" - I see temp during RAW recording (nightly) goes to 50C fast how safe is that?
I don't know if it's possible to quantify the safety.  At the warmer temperatures, you may see some variation or artifacts in the sensor output, and the 50D has a quirk where the FPS may lock to 22 fps.

Since the 50D can't do audio, the primary benefit of MLV is the useful metadata.  I recommend using MLV unless you find that it's not performing well enough for your needs.  If that's the case, then see if RAW makes a difference.

and final question, can't find the "crop" option anywhere :(

Tyvm for the help, Levis! I'll try that for sure.
It's funny because I always use ACR to CC my shots and then use AE to render out DxHD to Premiere. Shouldn't it have it fixed for me automatically?

I bought the VAF for the 50D based on your review by the time it was out. It's nice to know you're still following the 50 raw video thread :)

The safety I am talking about here is
 - killing something (sensor, killing some pixels for good, something else in camera..)
 - shortening life of something (shortening life of sensor, some other part?)

Any short term problems (like artifacts that will be gone after the sensor cools) are no problem :D

I noticed that my SD card (16G UDMA7 90MB/s scandisk, nothing fancy) is hot hot hot when I get it out of the camera when playing with video..

As a general rule, electronics don't like being exceptionally warm, especially if they weren't actually designed for it, so there's probably some risk, but we certainly can't quantify it.

I can't view DNGs on this computer, but my guess based on your words is that the automatically set black level is incorrect in the DNG.  The black level on a 50D DNG should be 1792, so you'll need to use exiftool to set it to the correct value.  It could also sometimes be a problem with the white level, depending on which parts of your image have a color cast.

Yeah, just checked. I even reset the ML config settings and the back wheel still does not function in the ML menus when I have Live View activated. It still changes the aperture when the menus aren't up but it's useless once I hit the trash button. Still works fine in the Canon menu though. Using the build from 8/8.

The existing "Fix black level" option does not work properly on the 50D because the wrong target value is in the code (1024, when it should be 1792), so don't enable it.  It's usually immediately apparent if the black level is wrong on your videos (strong green or magenta casts), and you can correct any black-level issues after recording by using exiftool.

Once this pull request (https://bitbucket.org/hudson/magic-lantern/pull-request/484/black-level-fix/diff) is fully tested and merged, black-level detection should be much more reliable.

Finally got round to trying out the latest nightly and actually shooting and processing some RAW video for once (I've only been doing h264 video) so I stuck the camera out the window:


Seems to work pretty well :). Workflow was raw_rec - MLVMystic - DNG - Adobe Lightroom (I use it for stills anyway) - 100% JPEG - VirtualDub (couldn't be bothered loading Premiere) - GoPro Cineform codec to AVI - Adobe Media Encoder to MP4 - Youtube.

Lens: Olympus OM 28mm f/2.8 Zuiko

Now, I realise there was some additional info required back when I mentioned this a few months ago but due to my day job getting in the way I've not had much chance to mess about with stuff. I still notice I can't change the lens aperture while recording is taking place either in RAW or H264. What's the latest on this? Is some more info/testing still required? I'm aware that on the 50D (with stable or tragic) adjusting aperture (or zooming a lens with variable aperture) causes brief pauses in the video as the lens stops down but having the option would still be nice, especially if shooting documentary style and you walk into an unexpectedly bright area. I'm aware a variable ND could be an option but it's not so good if you're needing to make adjustments in relatively low light situations and want all the light you can get until such times it's too much and you need to stop down. I have a couple of manual lenses with aperture rings that get around this, but it's my Sigma 10-20mm that I really want the ability to adjust the aperture on the fly again.

Sort of related: when trying to come up with a workaround I noticed if you try to adjust the ISO using the thumb stick shortcuts while recording the camera locks up and requires a battery pull. I then set them to aperture/shutter adjustment but still the aperture had no effect.

Amazing work as always guys though. Once all this festival madness is over here I'm taking a break away and hope to spend some time shooting some RAW clips.

Cheers

Hello,
Sorry if this is not related...

Just wanted to ask fellow Canon 50D users or anyone who knows whether you can turn on Liveview through the menu in the camera instead of by pressing the Liveview button on the upper left corner? Reason I'm asking is because I am planning to purchase a used Canon 50D and use it for underwater video with Magic Lantern. I currently have a Sea & Sea MX-40D housing and have used it with a Canon 40D camera for years, however, the 40D does not support video. I have also been told the 50D can fit in the Sea & Sea housing, however, there's no dial/switch on the housing to activate live view. Everything else would work fine by loading Magic Lantern, but I have no idea how I'd be able to activate Liveview while underwater?

Any ideas would greatly be appreciated.

Hello all.
I have just read the whole tread and I am really exited about getting a Canon 50D. I also got a Sandisk extreme pro 16gb 90mb/s. Is this enough to record continuous raw 1584 x 892? Some say you need at least 100mb/s...?

Thanks

I'm not familiar with this issue.  Are you using exposure override?

Just wanted to ask fellow Canon 50D users or anyone who knows whether you can turn on Liveview through the menu in the camera instead of by pressing the Liveview button on the upper left corner?
It'd be possible to make a menu option in ML to turn on LV, but I imagine that it'd be too niche of a use to be included in ML itself.  A simple module would probably be the way to go (or script, once that's possible).

Anyone knows if full-res silent pics is now part of the nightly build for 50D? I'll be shooting a time-lapse this weekend . . . . Please, please, please . . . .
I guess the "weekend" is already long gone, but no, full-resolution silent pictures are not in the nightly builds yet.  You can always compile a build yourself or request one (http://www.magiclantern.fm/forum/index.php?topic=12608.0).

So the 50D is only supposed to be able to record in 1568×882. Yet my ML menu only gives me 1920x1080 or 640x480  both 30FPS as options... I'm not in crop mode when i record and VLC claims the video is 1920x1080..

Which is the liar :) ? What am i missing?
where can i select 24fps?

Thanks for the help

If you can open your files with vlc then it's completely certain you are not recording raw, but h264. What is the extension of the files? MLV or RAW are the rawvideo formats.
You know how to enter the ML menu, right?
Title: Re: Canon 50D
Post by: Widget on August 30, 2014, 10:27:46 PM
When you're recording H.264 your only options are 1080p and 480p. You can override the encoder and shoot at 23.976 FPS, and for that you have to go into the FPS Override menu. I just wrote up a guide to that, so I'll quote it here:

Quote
If you're on the August 8th nightly this is easier, so I'd recommend installing that.

- First, enable movie recording (you know where and how to do that).
- Farther down the page is the FPS override. Enter the Q menu for FPS override by pressing the FUNC button.
- There should be a variable called "Desired FPS". If you have live view on it'll say "X (from 30)", where X is the default; if you don't have live view on it'll say "X (from 0)".
- Adjust the desired framerate to either 23.976 or 24.
- Set the "Optimize for" variable to "Exact FPS".

And that should do it. You're now recording video at a framerate of 23.976, which is a version of 24FPS that is compatible with NTSC/ASTC 59.94Hz displays.

NOTE: If you play an H.264 file made on your 50D with these settings, it will look like it was sped up. This is normal. Find a way to conform these files to 23.976 in your NLE of choice and it will work exactly like regular old 23.976 footage.

As for the resolution, 1568x882 is what you'd record in if you were recording .raw or .mlv footage. To use either of those formats you have to install the latest nightly build and enable the mlv_rec or raw_rec modules. From there, restart the camera and head into the Q Menu for those modules. If you get there and you're still not too sure what to do, come back here and ask more questions. :)

Yes, without exposure override enabled I can't change the aperture at all even in standby. With exposure override enabled I can adjust the aperture while in standby but not while recording in either H264 or RAW. In the stable build (and TL) I'm able to adjust the aperture but it does result in a brief pause in the video while doing so but still nice to have the ability to for any emergency adjustments needed. Camera is in 'M' mode.

On a side note I've also just noticed that in this nightly I'm using the blue LED doesn't turn off when you stop recording in RAW!

Hi guys, i'm trying for the first time Raw and Magic Lantern with MLV (not just raw, leaved on Off).

A question: is it normal i see some pink dot? I'm doing some test at 800 iso (think this can help the DR), but i see some kind of "noise" (not depending from iso, i guess), and in some frame really pink dots.

Any suggestions? Really thanks a lot 

Edit: i'm converting mlv to dng with "mlv converter 1.9.1", didn't touch any option in the program..should i?
Title: Re: Canon 50D
Post by: Widget on September 01, 2014, 07:19:43 PM
As I understand it, Canon DSLRs work very differently than other cinema cameras with regards to ISO; rather than shooting at a "native" ISO and then adjusting the middle grey point (Like the BMD or RED cameras), there is an analog gain stage at the sensor level, which means that changing ISO changes the response of the sensor. Therefore, for best latitude, noise, and colour response on the 50D you're going to want to shoot at the lowest possible ISO. (ISO 100)

I've never had pink pixels but I have had some dead ones. Have you worked with the MLV files in any other apps to see if it's just a debayering problem with MLV Converter? ML Raw Viewer works well too as I understand.
Title: Re: Canon 50D
Post by: Andy600 on September 01, 2014, 08:03:45 PM
Nope. Use whatever ISO you need to use to expose the shot correctly. If you limit it to ISO 100 you will not get the best SNR, especially in low light. Anything up to ISO 1600 is useable but anything above 800 ISO will need some post NR. ISO 200 on the 50D should give you the most latitude. Use the raw histogram and raw zebras. Some clipping of specular highlights is unfortunately usually necessary with the 50D to limit noise levels in the shadows and mid-tones down.

Pink dots are symptomatic of either a debayering algorithm not being able to handle over exposed shots well (as sometimes happens with DaVinci Resolve) or it can be the DNG converter app. Try a different one. MLV2DNG (PC) works well if you are working with Resolve. I haven't used RawMagic for OSX but that's worth a try too.

Just took a look at DPreview's analysis (http://www.dpreview.com/reviews/canoneos50d/19) and Andy600's post totally checks out.

Quote
The EOS 50D produced a fairly consistent dynamic range of about 8.5 EV from ISO 100 to 1600 dropping to 7.6 EV at ISO 3200 and to a minimum of 5.5 EV at ISO 12800 (due to shadow noise). However, highlight range is consistent (around 3.5 EV) up to ISO 6400.
Title: Re: Canon 50D
Post by: Renovatio on September 01, 2014, 10:53:37 PM
Well, for now did a manual cleaning of sensor and took some shots at 100iso, and the results are very impressive. We'll see, maybe could be the converter..

I'll look into it, but it might have been changed for a good reason.  You may also want to create an issue on Bitbucket (https://bitbucket.org/hudson/magic-lantern/issues?status=new&status=open).

Title: Re: Canon 50D
Post by: dpjpandone on September 06, 2014, 03:40:43 PM
My experience was that the blue light would hang when recording stopped due to buffer overrun. If you stop manually with the "set" button, it usually goes off as it should. This can probably be fixed by putting a check to see if recording was stopped by user (like movie restart does)

On another note, I got rid of my 50D when I bought a 7D, but I'm thinking of picking up another 50D for high FPS. Can someone please remind me what the max FPS that 50D can achieve in RAW? Also what is the max write speed the 50D can write to a CF card? Anywhere close to 82mbps like 7D?

50D max write speed: 70mbps
  7D max write speed: 80mbps

50Ds max. FPS is just 30 !!
While the 7D can go up to 50 or 60 FPS...I think...?

I think the 7D is better than the 50D, when it comes to RAW Video resolution. I'm not sure about which one has better low-light performance, but if you lookin at max write speed and max FPS, you should go with 7D...

set canon Q menu to 1920 30p and then open the fps override menu and  increase the fps number until it will not go any further. It will top out at either approx. 31fps or 36fps. I really need to know this so I can make an informed purchase.

from looking at fps-engio.c it looks like it will do 35fps, I just need someone to confirm please.

Not able to use the latest ML firmware. No option to access ML menu. I can use the Canon Menu but that's it. When switching back to July 16th it works instantly. I'm using a Komputerbay 128 1050X card.

Anyone know of a stable firmware after 7/16? The 7/18 build had pink frame issues.

- - Dogmydog - -

The 50D Canon ML firmware is probably the best thing to ever happen to me since I started shooting back in 2001. Definitely counting my blessings with this ML Cinema camera. It's been the best tool, dollar per dollar, that I've ever owned for training purposes and also for providing a real passion for exposure and composition. Got to say, for months on end, every time I went to a shoot the results were getting better and better. What a tool!

You're review of the Pocket Cinema dynamic range test, inside the shop, led me to buy the BMPCC. Eventually sold the BMPCC and kept the 50D.

... Shooting primarily with a GH4 these days. Missing the extended bit-range. Fortunately I still have the privilege to apply in-camera and post-production techniques that I've learned from the 50D. The GH4 would be half the camera it is if weren't for ML over the last year. Glad to be around.

Title: "New" 50D and the wonderful world of ML!
Post by: daveesl77 on September 18, 2014, 01:04:14 AM
I've been a long time user of ML on my T2i and happily donated to the project.  When I can afford more I will definitely donate more to help this great project!  So I want to first thank all of the developers, testers, commentors and idea folks...you are amazing!  I used ML extensively with the T2i and it never failed me.

So now that I'm getting older and my disabilities are making things a bit tougher, I decided to begin moving away from dedicated video gear and switch almost completely to DSLRs.  I decided to swap my old and trusty XHA1 to Adorama for a 50D and interesting lens.  I could not believe what I ended up getting...essentially a new 50D.  When I received it I noticed there wasn't a scratch on it.  No dirt, no dust, no prints.  I then checked the shutter activations --- 186 total !!!  This was after I did an initial test of maybe 25 clicks to just make sure it worked.  So yeah, I have a NEW 50D (for all intents and in my weird world).

Yes, I immediately installed ML and then the nightly build.  No, I did not read the instructions or advice (where is the fun in that, but I am doing it now).  Began pushing buttons, trying to do what I considered logical choices and voila, first RAW video shot 30 minutes after I opened the UPS box.  Yeah, it looked like crap, but it worked!  Next day I did another shoot, this time taking more time to figure things out, and it came out pretty good, not great, but in that I had not bothered to learn even the basic ops of the 50D and was just guessing at ML video, I'm happy.

So now I am reading all I can.  I'm watching scores of videos and fine tuning this monster down.  All I can say is...

THANK YOU, THANK YOU, THANK YOU!!!

This is FUN!!!  And it works beautifully.  I'm going on a short camping trip over the next couple of weeks, so I'll be shooting a bunch and will post some samples when I get back.

For things I have learned...

Main CF card is a San Disk Extreme 32GB, 120 MB/s.  It has worked flawlessly.

Secondary Card is something I wanted to test...got a SDXC to CF II adapter.  Inserted my PNY Elite SDXC 90 MB/s into the adapter, installed ML nightly on the SD card and began blasting away.  Have not tested a long video (figure it is going to be iffy), but it did work well on a 20 second shoot, RAW video.  Will be interesting if this thing actually works for any amount of time.  What does work well is using it with the still side.  Since I have a bunch of fast SD cards, this is kind of cool for me.

Once again, thank you all...from the Old Guy  Dave

The problem is that I don't have some of the options in the menus, specially Dual ISO and ETTR.

Can anyone help me with that?

I managed it with a nightly build. It was in the modules, just needed to activate them.

I'm tempted to pick up a 50D because of its CF slot and larger pixels for low light shots.

Is the max CF slot speed still 70MB/s?  If I'm shooting raw with 1920 width, what's the tallest frame height I can set for continuous shooting?  Or can I even have 1920 width at all?
Title: Re: Canon 50D
Post by: EVZML on November 06, 2014, 01:13:18 AM
Hi DigitalVeil!
With 50D and Magic Lantern you can shoot H.264 at Full HD (1920x1080), or RAW Video at max. 1568 width (I think it's 1568x882).
There is a option to use digital zoom x5 - with that option you can record Full HD RAW Video. BUT even with the fastest card, the 50D sometimes stops in that mode, and also you can't use x5 zoom mode for the most situations.
Also the highest FPS you can set is 30fps.

I got a 50D and it's a great video camera for it's cheap price. But you can not really compare to a 5D Mk3, because of it's bigger sensor (good for low light) and it's Full HD Raw video option.

If you are looking at the price - the 50D is the best camera you can get for it's price. If you want the best video camera and can spend money - you can find better cameras.

Don't forget: 50D was a photo camera without video mode, so it does not have audio recording. Also don't forget the CF cards are expensive for RAW video, I have 2x KomputerBay 64GB 1050x, each one for 85€ (something around $100). I think you can record something around 15mins on 64GB - one minute RAW video is like 4GB.

Any other questions? Just ask me! :-)

Thanks so much for being so helpful and kind!  I appreciate the in-depth answer, that clears up all my questions!  The only other thing I'm wondering - does setting FPS to 24 allow a slightly larger resolution?

The main reason I'm interested in one is that I can pick up a used one for $350-400 and shoot RAW at above 720p and get better low-light performance than my 70D.  I don't know if I particularly need a 3rd DSLR on my video shoots, but at the price I could get one, why not?  Lack of audio is not a big problem for me, as I prefer recording audio to an external device anyway, but I didn't know about the price of CF cards and how fast they fill up with RAW.  Thanks for that info!

Post by: kyrobb on November 06, 2014, 04:32:03 AM
24 fps won't enable a higher resolution no. I also wouldn't expect better low light performance than a 70D. I believe the 50D will perform worse actually, but not significantly. More or less the same.

Hi! I would like to ask for some help.
On the EOS 50D with the Magic Lantern do we have a length limitation? Or can we record videos as long as we would like to?

I don't have the 50D I just plan to buy one, and this is an important aspect.

I woud record spychotherapy sessions, wcich can be long, even about 2 hours.
I would not buy a dedicated video camera, if not necessary.

Thanks a lot!

Title: Re: Canon 50D
Post by: simulacro on November 09, 2014, 01:56:42 PM
it's not 5x, it's more like 3x. The 50D doesn't show the whole recording area in this mode. Besides, the recording area isn't centered, unlike the other cameras

I don't have a 5D. maybe someone with more experience using wide angle lenses for crop mode would help you. I use the 3x crop for tele shots, and it's a very good feature

Post by: daveesl77 on November 15, 2014, 07:21:45 PM
Well, I've been using the 50D for a month or so and I'm pretty impressed with what ML does.  Yes, I get the occasional hang, but that doesn't matter.  This works and is beautiful and I love it and...ok, enough of that.

I did a test shoot a few weeks back while shooting a class reunion.  Venue temperature was around 85F.  I had been shooting continuously with the camera for several hours, in still mode.  I shifted to raw video mode and let it fly.  It ran for over 6 minutes before it overheated.  That is far more than I thought it could.  Shooting on a San Disk 120 card.

There haven't been many updates or entries lately, so I figured I'd post these findings to let you know we are still here and very much appreciative!!!

I apologize in advanced if I'm asking in wrong place but searched forum directly and trough google and found ziltch :( .. so when I looked at the changelog of the nightly I seen some stuff that's out of place ... for e.g. webdavserver.. and since I was pretty sure there's no webdav server inside the 50d I went to look at the sources and found bunch of interesting stuff in the contrib directory. When I download nightly build it contains only the stuff that goes on the CF card and into camera, all these nice apps that exist in the project itself are not in that build so the question finally is: where can I download nightly build of "everything"? EOSMovieFixer for example or MLVBrowseSharp or ...

Some of the contribs may not be available as a pre-built binary.  In which case, you will have to build them (http://www.magiclantern.fm/forum/index.php?topic=9517.0) yourself.

Hi,

I recorded some video and I am not happy with the sharpness, but I am not sure if it's a limitation of the codec/camera or some other problem.

I had to shoot h.264 25fps, f8, 1/50, ISO 100.
The fotos from the same camera position (tripod) with the same settings and the same focus on the lens are fine.
The h.264-footage however is rather blurry in comparison (no example video right now, but I am trying to get the permit).

I know that the 50D was never meant to record video and I have already seen comparison videos from the beginning of RAW recording on ML that show a massive difference between h.264 and RAW in sharpness.
However since then the development of ML did not stand still and even normal videos made by stock Canon DSLRs  look way better than the h.264 I got from the 50D.

So, is it a limitation in the codec/hardware and I have to live with the blurryness/shoot RAW - or did I miss something and h.264 on a 50D should be decent?
Title: Re: Canon 50D
Post by: 1% on November 20, 2014, 05:10:39 PM
The only thing that can make 50D H264 liveable is finding where the flush rate is and maxing the bit rate settings so it records at the highest quality 100% of the time. For all of the memory and write speed on 50D the H264 is exceptionally bad.

I tried 2x CBR and it works, even with my old card.
For certain scenes I was able to get 3x CBR, but the results are nowhere near this sample from a 550D:

For all of the memory and write speed on 50D the H264 is exceptionally bad.
That's not what I wanted to hear, but it seems that way.
Well, off to figure out the easiest RAW workflow that I am willing to "endure"...
Title: Re: Canon 50D
Post by: 1% on November 21, 2014, 04:16:30 PM
I looked at it last night too... I still can't find flush rate or gop settings :( I'll keep looking tho... I did correct the mvr.h struct which has to go back into ML proper... your qscale isn't being displayed and I dunno where the "x" parameters are actually being written. You'd have to check your videos and see if they are really encoding at low qp #s or bit rate "CBR" isn't working at all. The fixed quant mode (qscale) is working for sure and slice is in the back end So overall a pretty normal 5DII/7D/550D style encoder. Maybe its the large pixels/low density sensor + too much compression?

What I find interesting is that there is 1 other mode, 640x480 60P from the looks of it.  If that 60P can be changed to then the 50D will do slomo.

Hi everyone.
I wonder what the latest is regarding using 50d with a field monitor when recording raw.

1. Does it work with both hdmi and avi (if that's the name for analog)?
2. Does it show overlay?
3. Does it impact performance?
4. What is the output resolution? The same as you film, 1080p/I or something else?
5. Is there anything else important to know about field monitors and 50d?

If you use one, which one and how?

Thanks!

Still wondering about this. Nobody have any idea? Also wonder if usb/tablet is an option when recording raw?
Cheers.

@Tullen: I tried a iPad 3 with DSLR Controller App (+ 2in1 Camera Connection Kit) - I can get it run, but it stops monitoring as soon as I start video recording (RAW or H.264 same)! So for me, it does NOT work right now. But maybe the future brings more options, or maybe I just have a slow USB Cable or Camera Connection Kit...

I think it's too much for the camera to record video and also monitors the video same time on another screen - for a camera that was not even build to record video! Think the CPU is too slow...but I'm not sure! :)

I tried installing ML today for the fist time.
I seemed to be having some issues (when i first tried live view i got some weird orange colours on my screen). Since then my camera is acting all weird.
I accidentally removed the ML files from the CF, took me a while to find out what was wrong but finally i restored the ML files (downloaded the files and transferred to the CF).

I decided not to continue using ML for now so i wanted to roll my camera back to it's normal Canon firmware but this seems to be a problem.
If i go to menu, it won't display the firmware (this means i cant update the firmware). The camera also doesn't show all menu tabs. I have to use the green automatic mode (at the top dial) just to even get a menu.

Is there any way to restore my camera to how it used to be?
I can't acces most of my menu's now, it won't give me live view, I can't change the iso. The camera seems to have lost a lot of functions and this freaks me out :-(

Hello,

I'm running the nightly built from Oct. 7 on the 50D and encounter weirdness with setting ISO:

(a) Whatever ISO is set in the ISO menu, the live view overlay remains at showing "ISO 100".
(b) ISO can only be increased when dialing down shutter speed and going below 1/27. Then, the shutter speed will stay at 1/27 but ISO will go up in 2x increments.

Is this a bug or a feature?

Sorry, should clarify:

FAT32 (didn't know the 50D supported ExFAT)
Camera drops frames consistently after around 4.5 min, which is roughly half the 32GB card.

ExFAT? . . . ExFAT is not supported on the 50D. FAT32 only - unless someone has figured out how to do it.

in non-crop mode, i can record 15-20 minutes using a Komputer Bay 64Gb 1000x card, 23.976 fps, Global Draw OFF, MLV Recording, and keeping the 50D in a shaded area. Here's what you also need to know - The most important factor - as far as length of recording - for the 50D is camera temperature. You must try to keep the camera cool. My recommendation is that you shoot in short takes pausing for a short period and turning off LiveView if possible before doing the next take. For example, on interviews, you can treat your questions as takes that way you have a chance to let the camera cool down a bit in between questions. Letting the camera cool a bit is especially important if you are shooting in hot sunny day.

i'm considering buying the 50d to shoot wedding videos. do you think using the settings above to get 15 min per 64gb card is reliable?
can you clarify what resolution i will get when you said non crop mode?
also, does this mean the 50mm lens will behave the same as on a standard aps-c non ML hack canon camera?

also confused about resolution. this camera cannot shoot 1920 x 817  ? if not what is crop mode and how does it affect things. does it crop the view of every lens used ?

the 50D doesn't have audio. It's a photo camera modified, and the hardware doesn't have the necessary stuff to do that. Youll need to record audio externally

The 50D tends to overheat after some minutes of recording, after that if you're recording in h.264 the frame rate will reduce automatically

the 50D in raw recording in non crop mode will record at 1568x882 and it has the same field of view that any lens on a aps-c camera

the crop mode is 2.4x aprox and my 17-85 in the wide end (17mm) would look like a 50mm lens field of view. In crop mode it can shoot 1920x1080

i'm considering buying the 50d to shoot wedding videos. do you think using the settings above to get 15 min per 64gb card is reliable?
can you clarify what resolution i will get when you said non crop mode?
also, does this mean the 50mm lens will behave the same as on a standard aps-c non ML hack canon camera?

also confused about resolution. this camera cannot shoot 1920 x 817  ? if not what is crop mode and how does it affect things. does it crop the view of every lens used ?

thanks

A few things in addition to simulacro.

If you're going to shoot weddings, you probably want some fair amount of shooting time. I'd recommend you shoot in non-crop mode. Non-crop mode has a drawback though - you will get Moiré and Aliasing when shooting wide angle and scenes with very fine details. To get rid of Moiré and Aliasing you might want to consider getting the Mosaic Engineering's Optical Anti Aliasing filter.
Title: 50D raw video samples
Post by: daveesl77 on December 23, 2014, 11:48:20 PM
For those new here and wondering if ML really does work with the 50D I can tell you it does.  I used my 50D as a 2nd/3rd level camera at a wedding I shot last weekend and it ran like a clock.  A number of people were amazed seeing it do timelapse without an intervalometer hanging off of it.  Thank you guys so much for this!

Here are a couple of samples I did with the 50D shooting raw video files.

Test 2 was shot on a rainy, stormy day.  Primarily doing short clips.  No color correction done.

also, it will stop recording when reaches 4gb ? that's a little over 1 minute?

For those asking about the external monitor:
I've been using my 50D to shoot my web series (www.youtube.com/opostodosexo) since sept/2013 and I use a liliput 669 external monitor connected to it since day one. It works incredibly fine, but I'm not sure if it affects the write speed on CF cards. I also use a battery grip.

The 50D tends to overheat after some minutes of recording, after that if you're recording in h.264 the frame rate will reduce automatically

About the heating, all I can say is that I constantly change batteries and cards between shots and leave the card slot and battery slots open with a dedicated fan just for the camera. The place where we record is really hot, so in the summer we have to be patient, but the camera never failed to deliver suberb results in MLV rec mode.

I invite you all to check my web series at YouTube, since we recorded 69 episodes so far, all using magic lantern hack. Here is a playlist with English subtitles.

Cheers,
Leandro

@drkamikaze: I'm currently looking for the easiest yet still flexible one and as of today my preference would be:
1) shoot mlv
2) raw2cdng for conversion to cdng
3) davinci resolve for everything else (debayer, edit, color correction, output). For color conversion using VisionLOG, however that is still uncharted land for me

Dear fellow 50d owners:) I have some issues understanding the concept of movie mode implemented in current nightly. It seems that Exposure Override option is dramatically changing movie behavior. Having it disabled, no matter what you set before recording, ML tries to keep shutter speed close do 360deg, which for h.264 is around 1/30, changing the ISO accordingly when moving from bright to dark scenes. With Exposure Override enabled, you set settings before recording and ML honors them but not adjusting for changing light conditions. Could someone be so kind and give me a hint on how to override standard shutter speed of 1/32 to shorter value, say 1/60, to achieve 180 deg, but still keep the possibility of automatic exposure adjustment? Is it at all possible in 50d?

Thanks

Been having a real challenge here with 50D and feeling like a real noob  :-\.  It doesn't let me adjust the resolution. It's either 640x480 on or off. When I turn on the HD, when I go to the Raw Video (MLV) option on the movie menue, it's either "On, 1568x882" or OFf. No in between.

I really don't care about shooting HD, I just want to shoot higher resolution than 640x480 which is way to low for my needs.

How do I change the resolution??

@Itias: What is the advantage of shooting MLV over RAW.rec on the 50D? My understanding was that the big advantage of MLV.rec is that it can record sound, which the 50D can't do anyway...

Also, I would love to try DaVinci Resolve, but until I upgrade my computer, I am unable to run it. Hence Adobe Camera Raw and After Effects for DNG processing...

The card speed improves a lot, at least in my case. I have two 60MB/s cards, and the recording times have improved since I installed the MLV module

Also, the MLV format brings all the metadata which is important for ACR

Post by: Edin Edin on January 28, 2015, 12:50:01 PM
Edin, what was your workflow?

I outlined most of it on vimeo. Here's the summary.

- Extract DNG(s) from MLV file(s) with MLVBrowseSharp
- Edit and/or correct DNG frame(s) in Adobe Bridge with ACR (this includes resize to 1920x1080)
- Process all DNG frames to high quality (12) JPEG via Photoshop
- Use FFMPEG to join JPEG sequence to ProRes 422 HQ
- Cut and grade in Premiere Pro and export to H.264 Vimeo 1080p HD

Somewhat peculiar maybe, but I really like it. I also use AnotherGUI to interface with ffmpeg, since I get to create my own presets for specific fps and codecs etc and do batch processing.

Unfortunately I was not able to find the information I need via google or the forum, maybe I used the wrong keywords.

Hey Everybody,

First post on ML forum. I passed a few hours to clearly understand the max resolution, as of today, for RAW video continous recording on 50D. I think I'm not the only one who'd like to know, so if someone has the answers...

What's the max resolution ?

@ 24fps:
1- In Full Sensor 16:9
2- In Full Sensor 2:35
3- In Crop Mode 16:9
4- In Crop Mode 2:35

@ 25fps:
5- In Full Sensor 16:9
6- In Full Sensor 2:35
7- In Crop Mode 16:9
8- In Crop Mode 2:35

@ 50fps:
9- In Full Sensor 16:9
10- In Full Sensor 2:35
11- In Crop Mode 16:9
12- In Crop Mode 2:35

I don't have all the information you're after, but I can offer some. With a fast enough card, you'll be able to record continuous raw video at:
1568x882 (16:9) Non-Crop mode @ 25 fps (57.6 MB/s) or @ 24 fps (55.3 MB/s)
1568x668 (2.35:1) Non-Crop mode @ 25 fps (43.7 MB/s) or @ 24 fps (41.9 MB/s)
I have little experience with crop mode so I can't help there, but unfortunately there is no 50 fps on the 50D at all.
Hope this helps!

I was looking at the latest Nightly and saw that the 50D Changelog includes:

"df0bbfe | g3gg0
mlv_rec: major fixups for card spanning and preallocated file names"

It was my understanding that the 50D can't do exFAT or card spanning. I think it therefore has a one second or so pause when recording all formats H264, MLV or RAW. For stock settings of H264 the limit is reached at 4GB which is about 17 minutes into a recording. Am I missing something?

Commited changes in main branch's code will start new builds for all platforms (but 5D.123). No matter if your cam is affected by those changes or not.
But there were two changes affecting 50D, too:
MLV was limited to 40 GByte for a take: http://www.magiclantern.fm/forum/index.php?topic=9848.msg141340#msg141340

I have a 50D in the mail on its way to me. I've never used an SLR camera before, but the 50D appealed for its low light abilities and RAW video recording with MagicLantern. I scored it and four lenses for $555 on eBay.

The one thing it doesn't come with is a decent CF card. And after spending several hours reading through the forums, I'm still a little uncertain which card to get. I'm going on a trip to Europe for three weeks, so I'd rather get two in case one goes bad. I'll have my laptop to offload the cards.

Are the KomputerBay 128 GB 1066x cards good with this camera? They're by far the cheapest per GB 1066x and I'm tempted to pick up a pair.

Also, is any USB3 card reader plugged into a USB3 port okay? Or do I need a specific one for specific brands of cards? I've read stories here of disasters, but they seem to involve USB2.
Title: Re: Canon 50D
Post by: Walter Schulz on March 10, 2015, 05:22:20 PM
*Most* readers with USB 3.0 are ok. Some may require firmware update. Others may kill your card. And it doesn't matter if connected to computer by USB 2.0 or 3.0.
You need UDMA-7 compatibility. If you find "UDMA" only: Stay away.
Only exception I know: Kingston FCR-HS3. Nothing to read about UDMA-7 but recommended by KB support.
Other decent readers: http://www.cameramemoryspeed.com/reviews/card-readers/
Unfortunatly no KB cards in their lists.

Hi guys,

Yesterday something strange happened to me when i tried to load last nightly build: seems i don't have a complete manual control of the camera, so if i turn suhtter then even iso changes and so on if i close or open lens i changes shutter too.  With the last one seems to change settings on its own just look around with the camera in the room.

I tried old builds and seems are just less problematic. What can i do? Thanks a lot. I'm on "M" mode, of course, i guess there's some setting i have to touch.

I tried to remove magic lantern with format option, and even by installing magic lantern and then waiting for removing boot flag.
Then i update to official 1.0.9 firmware even the camera was already there, to try to reset it to default firmware.

And then i update with last magic lantern e one old build (casual: 20 febrary).

Nothing, the problem is here and expo lock was turned off, of course.

By updating Canon's original firmware you actually won't change a bit. It won't reset camera settings at all.
Use Canon's menu to restore factory defaults and don't forget C.Fn settings.

Hi guys, don't know again if this is the right place but it's about 50d...Took it again, it's fantastic but a few question:

- Bit rate: what should i choose for a good compromise? Have a fast card (komputerbay 1000x), want to improve raw video as possible but with costant shooting. Now i'm on 1.4x, can it go?

- Profile: i'm on neutral, just 0000. Has to set the best for color correction in post, so neutral, but is there something better, or should i touch some parts of neutral? Just an advice, from your experience.

A note: in crop mode i tried to get the best resolution from 2,39:1 aspect ratio (something like 1958*...), camera hasn't stop but then, with internal file manager, and with the file playing, i notice some mistakes, errors, such as "screen tearing" (or just lines..) on certain frames, and "blacklash" (don't know how to say, some frames goes, then seems to stop but i'm the other frame and seems i skipped a part of the video but could be just the internal player of the camera)

2000x852 is 2.35 not 2.39.

Title: Re: Canon 50D

Can you check it for me, please? Thanks
Title: Re: Canon 50D
Post by: rbrune on March 31, 2015, 10:51:45 PM
Well the issue is that the next higher value you can set in mlv_rec after 1920 is 2048 - which is too much for the card interface.

Here the max. achievable frame sizes in crop mode - if the card plays along:
2.39:1    1920 x  804  24p     61.8 MB/s     4.01x eff. crop
2.35:1    1920 x  818  24p     62.9 MB/s     4.01x eff. crop
1.85:1    1792 x  968  24p     69.5 MB/s     4.30x eff. crop
16:9       1728 x  972  24p     67.3 MB/s     4.46x eff. crop
Title: Re: Canon 50D
Post by: Renovatio on March 31, 2015, 11:01:48 PM
Yes but if you push the higher resolution, camera will set the best it can, so the best is 1984*830.

I'm on 2,39:1 because for cinema is so near to 2k scope resolution...

Thanks anyway

@Renovatio: I forgot about the max. crop buffer size, which is 2000x1080 for the 50D - so yes if you set 2048 it will fall back to the next multiple of 32 below 2000, which is 1984. So 1984 is indeed the achievable maximum.

I need to shoot a genuine comparison test to be sure, but it seems to me footage from my 50D does seem more organic looking than that from a recent test I made with my 60D. Even though I was using the maximum full sensor width (though only lasting for about 10 seconds) which is higher resolution than the max res of the 50D, somehow the video looked a bit grainier in comparison (not what I was expecting). The 50D footage has always looked quite film-like; seems there's something about these older sensors that is quite attractive. I bought a second hand 5DII, which is a similar era Canon, for that very reason to experiment further with ML raw video. Since I've run out of money, I need to decide which one I should buy the VAF filter for because I can't afford filters for them all.
Title: Auto iso and aperture control during raw recording
Post by: Grzegorz on April 24, 2015, 01:25:39 AM
Hi,

I have just started today with raw recording, not very successfuly though. I can not get auto iso working. I set it to auto, but when I go to live view, it stays at 100 or 200 with HTP on even if the scene is severely underexposed, same when recording raw video. Then when I check the settings, I see it reverted to 100, or 160 with HTP on.

Another question: In live view I can change aperture manually through camera body controls and I see the effect on the screen. When recording it seems changing aperture is not possible.

Your help will be highly appreciated!

Hello,

A little help please

I have no problems using Focus peaking on my 1100d but simply cannot get it to work on the 50d?

It should be working right?...

Thanks in advance

Title: ML Top/Bottom Menus
Post by: garry23 on May 06, 2015, 10:17:51 PM
I have the latest nightly running and I have 'just' noticed a strange thing: although I'll be the first to accept it is not strange and I haven't noticed it before :-)

I like the LV ML menus at the top and bottom, ie not both at the bottom as here they clash with other ML info, eg the depth of field reporting.

It seems I can only get the ML menus top and bottom if I use 16:10 or 16:9. And when I use these the menus sit inside the LV.

In other words on the 50D you can not have the ML menu bars hard against the top and bottom LV edges.

Is this right: or am I missing a setting?
Title: Re: Canon 50D
Post by: a1ex on May 07, 2015, 07:48:18 AM
This is actually a bug.

To put the info bars on top and bottom, either enable some overlay that goes on the bottom side (histogram or waveform), or choose a different screen layout (Display menu).
Title: Re: Canon 50D
Post by: garry23 on May 07, 2015, 03:05:48 PM
@Alex

Thanks for the info.

BTW relative to the 5D3, where the menu bars are offset by a few pixels from the top and bottom, on the 50D it looks like about 3/4 of a menu bar depth offset.

It doesn't worry me at all, ie not a high priority item as far as I'm concerned.

Cheers

Garry

Post by: Grzegorz on May 15, 2015, 02:17:23 PM
Hi,

I am on May 3rd nightly and it works well for me - I have shot 15-20 minutes of raw already plus some .mov. Installed following all the procedures, including 50D in M mode with all settings reset to factory values. I am still a newbe with lots to learn.

By the way, can anyone knowledgable confirm that it is not possible to change any settings like aperture, shutter and ISO during recording (neither raw, nor mov)?

Another question crops up in crop mode - as I zoom-in with a lens (camera stationary, tripod mounted) the composition changes, i.e. my stationary subject which has been at the center initially, as I zoom-in slides to a corner. Has anyone got any solution?
Title: Re: Canon 50D
Post by: robertgl on May 16, 2015, 07:03:55 PM
I think the 50D has always had framing issues in crop mode; not sure if that's fixable, but it would be nice.

What's the max resolution for crop mode now? Is 1920x1080 continuous doable?  I remember TL could do continuous a little bit above 1080p
Title: Re: Canon 50D
Post by: moomilk on May 16, 2015, 10:16:51 PM
Hi guys, could anyone tell if it is possible to change the video resolution in standard ML (H.264) video recording on 50D?
Or confirm that is is fixed to 1920x1080 or 640x480? (these are the only options I find available in the menu)
I would like to use different high res aspect ratio like (1920x1200 or 1600x1200 etc ) 16:10 or 4:3 \ 3:2 if that is possible, think even 1280x800 would do.
That would really help before I got a fast CF card to use RAW .))
Thanks!
Title: Re: Canon 50D
Post by: Grzegorz on May 17, 2015, 09:14:16 PM
@ moomilk: As far as I know H.264 offers just the two modes you have mentioned.

@ robertgl: Crop mode with a 64 GB Lexar x1066, no frames dropped, I am able to get: 1792 x 1080 and 1856 x 1044. Though I've never tried for longer than 5-6 minutes, fearing of overheating.
1856 x 1080 I get a dropped frame after a minute, or two. Do not know, if these are the best results obtainable. Probably not. I would appreciate any remarks from people who get better results on how they do it.

Post by: Grzegorz on May 17, 2015, 10:57:14 PM
@ dlrpgmsvc: Did you format your card in any particular manner? Any particular settings, or just ML default and global draw off while recording?

At 1920 x 1080 regardless of settings I try I am usually getting 32-39 s. of recording before a frame is dropped (occasionally a bit less, or a bit more) :( which is in line with the info displayed by ML while selecting this resolution. According to this information my write speed is 72-77 MB/s while I need 82.9 MB/s. for continuous recording.

Forgot to write I am always talking/writing about 23.976 fps  ::)

Any suggestions?
Title: Re: Canon 50D
Post by: dlrpgmsvc on May 18, 2015, 08:30:11 AM
@Grzegorz:: yes, 23.976fps global draw off, video small hack on, card pre-heating on at maximum value, and i format the card off-camera on pc with 64k buffer maximum value. All these parameters makes a gold combination, at least for my experimentations

 :) Thanks dlrpgmsvc.

This is probably it. I've been using mlv all the time, because in my initial testing it had definately been more stable than raw rec. I've just tried raw rec again. First time approx. 200 frames vs. 700-900 I get from mlv, BUT second try resulted in 1930 frames. The recording stopped probably because the camera was getting too hot. I hope the temperature is to blame for the four corrupted frames I got in this 1930 frames attempt (one totally black, three with pink lines or rectangles and some small black rectangles). I will try again tomorrow. Thanks again.

Title: Re: Canon 50D

The cards are akways aligned. You must set the buffer to 64 to boost the speed. Also use raw rec and disable global draw

Thanks for the response - I can't find any thing about adjusting the write buffer - how do I do it?

Hi,

unfortunately further tests did not bring any improvement. The thing I still do not understand properly is card formatting (I've been using guiformat.exe to format in fat32 with allocation unit size 65536) and adjusting buffer size. 

dlrpgmsvc would you be so kind to explain this in more detail? How do you format on a PC and how do set the buffer to 64?

Have a nice day, everyone!

I second this request, if dlrpgmsvc gets a chance. A quick run through would be great. I've just begun playing with my 50D, and have been trying to compile a best practices list, and have only formatted in camera.

Can't find an answer to this: when deleting raw files from  the card, either in camera or on a mac, the card seems to retain hidden files? These are hidden in both camera file manager and Mac Finder. The space is only released when the card is formated in camera. How can I delete files on camera and free up the space without deleting all the files by formatting? Is this a general issue with other cameras?

Could there be an option for delete to release the space when deleting on camera,  without having to Off/ON? I aim to shoot drama and be able to quickly trash false starts bad takes etc Thanks.

I wish 2048 resolution option would be unlocked -  2.20:1 2048x930 for instance would be continuous on most cards; 2048x1080 could probably record for about 45 secs to 1 minute on a fast card

Bitrate issues aside, is there an issue with the camera that prevents 2048 ?

Yes. the 50D doesn't have it. The maximum horizontal width in crop mode is, I believe, 2000px but has been limited to 1920. If you cropped to 2048 you'll just have black bars, not image data.

I've been using Tragic_Lantern_for_50D_Andy600Build.2014Feb01.50D109 on the same card for over a year with no issues, but I decided to test out the last nightly to get benefit from the new features.

Is anyone using a stable nighly with the 50D?
I'm gonna try another card to see if results change.

Thanks!
Title: How to prepare CF for best performance
Post by: dlrpgmsvc on June 03, 2015, 04:29:15 PM
Hi guys !

At great request, I'm here to explain how to format your CF card for 50D at his best to obtain the maximum performance on RAW VIDEO.

Card used : komputerbay 64gb 1000x
                  512 Bytes sector size (card bios)
                  64K max allocation unit as FAT3 and as sector size <= 512 Bytes

ML version used : a very old one, so on the new versions the things should be even better. I will test this on new versions and I will report soon !

The trick is to have an "Aligned partition" and to set allocation unit as high as possible (64K is the max, in this case, because camera use FAT3 and the Sector size is less or equal than 512 bytes). How to obtain this ? Simple ! Follow this procedure :

First of all, dowload one of these two tools :

- miniaide free edition partitioner/formatter (miniaide fat32 formatter home edition)

- MiniTool Partition Wizard Home Edition v8.1.1

With MiniTool (but it is similar also for MiniAide) choose "delete partition" then "create new partition" and choose to create as "logical" and file system "FAT32" and cluster size "64 KB", leave the other options as default and select "OK" and then "apply" and "yes". Then "format partition" and choose file system "FAT32" and cluster size "64 KB", all other options leave as default, then "OK" then "Apply" and "yes". Then "align partition" and "apply" and "yes" only if it accepts it and if it don't tell you that there is no need to align because it's already aligned.

Canon 50D
1920x1080 - 23,976fps - 5x zoom
card warmup 1Gb - GD off - All disabled in ML and Canon menu
only FAT32 supported on camera

FAT32 supports 512,1024,2048,4096,8192,16k,32k,64k
(128k,256k for sector size > 512 bytes)
But sector size is hardware determinated by the CF builder, and cannot be changed by software.

DEFAULT FORMAT ON CAMERA HAS FOLLOWING PARAMETERS ============
cluster size (partitioning)=31k
allocation unit (format)= 32k
80,0 Mb/s constant ML write speed once warmed up
1280 frames recorded as mean value

CUSTOM FORMATTING 1 ====================
cluster size (partitioning)=64k
allocation unit (format)= 64k
81,2 Mb/s constant once warmed up
1600 frames written as mean value

CUSTOM FORMATTING 2 ====================
cluster size (partition)=4k
allocation unit (format)= 64k
81,2 Mb/s constant
1600 frames written

CUSTOM FORMATTING 3 ====================
cluster size (partition)=64k
allocation unit (format)= 1k
35,0 Mb/s constant
80 frames media

All in RAW module, NOT MLV! All Global Draw disabled, card warmup 1gb, beware!

Can you provide screenshots of what you are seeing in Live View, what your settings are on your Overlay tab, and maybe even what your settings are on your Modified tab?

You asked earlier about setting "Kill Canon GUI" to OFF.  When that is set to OFF, the Canon GUI is not suppressed, and competes with the ML GUI, which is why there is flickering.

Thanks dlrpgmsvc for the formatting guide.

Unfortunately it is not clear enough for me (first time installing and working with Magic Lantern). The first steps using MiniTool are very clear. Unfortunately the text under 50D is not clear enough. Is there something I should do in camera? Or is this just explanation of what happens if we do it in another way? Maybe I just get confused by the fact that you do not write in step by step instructions any more. I understand that I should sett the camera to 1920x1080 - 23,976fps - 5x zoomcard warmup 1Gb - GD off - All disabled in ML and Canon menu
only FAT32 supported on camera. But how about the in camera formatting that you write about?

So, after formatting the card using MiniTool, is there anything else I need to do?

Title: Re: Canon 50D
Post by: dlrpgmsvc on June 17, 2015, 04:18:38 PM
@ Tullen: after formatting with minitool you have to transfer the ml files to the card and then use it inside 50d! The in camera formatting written down is just to show you how slow it is compared to minitool system
Title: Re: Canon 50D
Post by: Tullen on June 17, 2015, 04:26:42 PM
@ dlrpgmsvc

Thanks for the fast answer. When I put the card in the camera it said the card was not formatted and needed to be formatted in camera. Should it not do this? Also, do I need to create the MISC and DCIM folder myself after formatting on the computer?

Thanks
Title: Re: Canon 50D
Post by: dlrpgmsvc on June 17, 2015, 04:30:01 PM
No folders creations needed beside the ml dir structure. This error is because you partitioned the card but not formatted. You jumped over the last instruction passages...
Title: Re: Canon 50D
Post by: Tullen on June 17, 2015, 04:48:20 PM
Actually I did format the card. I guess I would not otherwise been able to put the ML files on it? Also did not work when I tried to use the EOScard software. Both times the camera says the card is not formatted. Its a Lexar 64 GB 1066x btw. Tried it three times with same result. Hum...
Title: Re: Canon 50D
Post by: dlrpgmsvc on June 17, 2015, 04:52:30 PM
You have first to install the bootflag to the 50d by using the methods described elsewhere depending on card size. Without following my format techniques. Then you can partition and format the card as I described. Then you can transfer the ml files structure to the card by computer. Then insert the card inside 50d and fire it up!
Title: Re: Canon 50D
Post by: Tullen on June 17, 2015, 05:06:06 PM
Is it possible to use spoiler so the pictures does not take up space for people who are not interested?

Yes, I apologize, I am quite used to using forums for questions and giving/receiving support so I should have known to give all information from the start.

I have already installed ML on the camera. In fact, if I allow the camera to format the card I can use the ML Benchmark to test it. I have a Kingston FCR-HS3 card reader. Card is a Lexar 64gb 1066. CLARIFICATION: If I format in camera and then put the ML files on it from computer it will boot, not straight after in camera formatting.

What I notice is that the color of the bar of the CF card in MiniTool does not get the same blue color as the other disks in my computer after formatting, but I think this is because it is set to Logical instead of Primary. I will try with the other program you recommended and see if I got the same results.
Title: Re: Canon 50D
Post by: Tullen on June 17, 2015, 05:20:52 PM

Well, it works if I chose Primary, but not sure if its actually faster than in camera formatting. Will do more test later when I have time. For now it says my card only can do 50 Mb/s which is a bit sad. Will have to see if I can get it to do better. Bought from China so can be a fake for sure.

So, these are the three benchmarks I have, two different Komputerbay 64gb 1000x and one Lexar 64gb 1066x (fake?). Seems they have roughly the same speed. Do you guys think I am doing something wrong or have I been super unlucky with all of them? Is there special settings I need to activate? I read about changing to playback mode or something, but cant figure our how. Read somewhere that you can send back Komputerbay cards that do not live up to the rating.

EDIT: Thanks Walter
Komputerbay 1
Komputerbay 2
Lexar

Last thing before I go to bed. It often happens that the "Scanning Modules..." box show up and then do not disappear again. Is this a problem? It happens after I update the firmwire in order to make the card bootable.  It goes away if I restart the camera.

It also says, CROPMKS dir missing a short while. Then it dissipaters, does that mean it has been found or that I have a problem?

Is there a setting to enable auto span after the 4gb raw rec span? Today a pair of takes went past 4 gb, and the file format jumped to a RAR archive. The .RAW file won't load into raw2dng but the archive will, however everything is corrupted. Is there a way to salvage these takes, or are they toast? The first several shots were 2-3 gb and are fine, btw. Also, after the first over 4gb, a couple shots reverted back to h264-1080, before resetting (I never touched anything) and trying another go at raw? I'm new at this, but wondering if anyone has had this happen and has any advice?
specs were, Global Draw off, non-zoom raw at 1568x882.

The 50d ONLY does 1080p raw in crop mode. In full sensor mode it's limited to that resolution. But you'll find that it scales nicely to 1080p in post.

Post by: khail on July 06, 2015, 12:55:34 PM
hi guys, this is a random idea, the over hearting that the 50D is prone, is it because the live view is on always? If so, I found a car monitor a really cheap sd screen that is around the same size as the 50d screen and cost about 10US, do you think turning off the 50D's screen and streaming the video out to the car monitor may help with the heating issue ?

Go to ML Video configuration, then Raw configuration. you'll have this preview modes in crop mode: Auto., Canon, ML Grayscale, Hacked.

he over hearting that the 50D is prone, is it because the live view is on always?
Bigger sources of heat than the LV are the sensor, the camera processor and battery.  You can do nothing about the sensor and processor but you can try a external power source.

Either one. But that will not help that much. The best way to manage the 50D is to understand that there is a time and temperature limit to recording RAW whichever comes first - If you're shooting in a hot day, your max temp will be reached quickly and the camera will shut down or lock. If the room temperature is cool, then the maximum temperature will be reached during recording. The bottom line is, with the 50D you have to plan your shots with it's limitations in mind. For example I shot the documentary below in it's entirety with the 50D. All shots lasted 2 minutes or less with a bit of a break in between to let the camera cool off. During the scenes in the roof I kept the camera in the shade when idle and of course, audio was recorded externally.

Thanks.

Most of the interviews were shot with ML RAW (Non-crop mode) and most other scenes were shot with MLV RAW. The RAW files were exported with the now defunct RAWMagic and most of the MLVs were exported to DNGs with MLVMystic. I processed the RAW DNGs with Adobe Camera RAW. The debayer in ACR did a good job of removing most of the color noise. In later shots I improved the aliasing by using Mosaic Engineering's Moire / Aliasing Filter for the 50D. There is a mix of scenes with and without the filter throughout the film. For example, the scene at 7:40 was shot without the VAF filter and the scenes of the credits starting at 14:19 were shot with the VAF Filter. The VAF filter does a pretty good job of cleaning out the image and fixing the aliasing especially around sharp edges. Some shots were filmed in crop mode such as the one at 00:40 and 00:24. The quality of crop mode was much better but it limited my lens' range so I couldn't use it for most shots. So here's my step by step workflow:

1. Camera's PictureStyle was set to Neutral and the option for "Absolute zero sharpness" was turned on in ML.
2. Scenes were shot in RAW or MLV Raw.
3. RAW files were exported to DNGs with RAWMagic or MLVMystic.
4. DNGs were brought in to After Effects as DNG sequences. In AE Moire and aliasing was corrected and interview audio was imported and synched.
5. From After Effects, DNG sequences with synched audio were sent to Adobe Media Encoder.
6. In AME I exported to Apple ProRes 4444 (I selected the options to rendered at Maximum depth 32-bit, and use maximum render quality).
7. ProRes files were imported into a Premiere Pro project. Further color, slo-mo, and audio corrections were done in Adobe Premiere with round trips to SpeedGrade, After effects and Adobe Audition.
8. Finalized Premiere project was sent to Media Encoder for final file export to upload to vimeo.
9. Media Encoder setting for Vimeo MP4 upload file:

Format: h.264
Size: 1920x1080
Profile: High

RAW-Video and also MLV-Rec are working really great.
But sometimes I would like to use the usual movie mode with MOV video files, and not RAW-Video, for filming events etc.
When I record MOV files I set the FPS to 23,976. But when I playback the video files on my PC, it plays back very fast, looks like it plays back in double speed or something.

Everybody ever has the same problem, or know how to fix this?

That's because your MOV file is most likely playing back at 30fps, not 23.976. If you're using quicktime, quicktime will play back the file at 30fps if it cannot read metadata from the file. To playback your files at the correct speed, you may have to conform the video file using something like apple's old cinema tools utility. Or you can also put the file in an NLE's project with the proper playback speed set in the project's properties.

I use two solutions for this, either "interpret footage" in premiere pro or exporting the h264 stream and muxing it again to a .mp4 file, with mp4box:

Code: [Select]
mp4box -add MVI_0002.MOV#video -raw 1 -new temp
&& mp4box -add temp_track1.h264:fps=10 -new dest.mp4
&& del temp*

Title: Re: Canon 50D
Post by: reddeercity on July 25, 2015, 06:40:01 AM
Hello 50D users , I have a opportunity to buy a used 50D with 44K shutter activations , 5 battery plus a battery grip for about $250 CDN. ($190.0 USD)
I figure that a very good price as long as everything works, I was thinking of using it for a B-Cam on interviews with ML Raw Ver1.0.
As my Main Camera is 5D2 I will record MLV+audio at 1872*936 A.R. 2:1.
I have read 1920*1080 @23.976p in crop mode is continuous ? (True?) or even 1920*960 @23.976p A.R. 2:1 .(I have 1000x & 1066X Lexar CF Cards)
That would match the 5d2, My Question is there any pit fails I should know about the 50D ?  before I buy it on Monday.
Also as I have a Ninja HDMI Record , dose the output have side bars like 5d2 ?
Thanks in advance  :)

Post by: DeafEyeJedi on July 25, 2015, 09:46:26 AM
That's definitely a steal especially with the batteries included. Nice! [emoji108][emoji106]

But perhaps on the other hand you could double up that price and get yourself a nice mint 7D to use as a B-Cam?

I'm afraid you won't like the heat issue with 50D... There seem to be a slight workaround to it though. Like wait in between takes for it to cool down, etc.

Heck even I've been tempted to pick one up within that price range just to have & shoot RAW/MLV with it. Wouldn't spend more than $200 for the 50D.

Guess can't go wrong either way, I'd say?

A faster card will help stabilize recording but you will also have to take into account that more CPU heat will be generated by recording at a higher resolution. Crop mode does a full read out of the area being cropped which gives you more detail and cleaner images but it also requires more processing power. The CPU will be working harder so it will generate more heat. The only way to know how long you can record in crop mode at 1920x1080 - using a faster card - is to actually run tests to see how long you can go before CPU temperature stops the recordings.

Hi!

I've been using magic lantern for a while now, both on 550D and 50D and it is great. Especially RAW on 50D is amazing even with al the problems that it has. I recently discovered dual-iso and what it can do in terms of dynamic range, would be lovely to use it in video mode too but my menu seems to complain: (MOVIE) This feature requires you shooting RAW.

This is even though live view is active, RAW video mode is active,... Works great with stills, just can't seem to be able to get it in RAW video, tried all mode dial positions. What am I doing wrong?
Running on Nightly 2014 oct 07(I know quite old, but still, works stable enough for me)

Also a feature idea/request: One of the main issues besides stability and overheating is syncing audio. It would be great if the camera could output some kind of beep or other syncing signal out of the video out port so matching with an external recorder is less cumbersome. Maybe even with some code referring to the video file. Would this theoretically be possible with the hardware in the 50D?

Overheating issues can be reduced significantly(but not resolved) by using a 'dumb' battery together with a large external battery(Amazon DE: RAVPower 15000mAh with 9V out) on the cheap. Anyone have any further tips to cool the sensor without one of those astro peltier/heatsink mods?

Thanks!

Yes. It does not look that clean to me either. But there is a way to clean up non-crop mode - use Mosaic Engineering's VAF filter for the 50D. I have one. That's the one I use to clean up the image in non-cop mode.

This (http://www.magiclantern.fm/forum/index.php?topic=14909.0) shows you the max bitrate your camera can write, and this (http://www.magiclantern.fm/forum/index.php?topic=14674.0) shows you what the required bitrate is for (any given flavor of) raw video. The difference between these two numbers is what will fill up your buffer until it runs out of space and then the recording will stop. I don't know what your buffer size is, though. Might be easier to just try it.

Patience is a virtue. Simply.... Once ML is installed, press the Trash can button to bring up the magic lantern Menu. To access the Video Modes, you must first start Live View, then load the "mlvrec.mo" module from the modules menu, then re-start the camera. Once the camera is back on, start Live View once again and you should have ML Raw ready to shoot. Set FPS overwrite first in the video menu.

I'm interested in videoing macro using the 50D but am a little concerned about the warnings of damage and bricking.

No problems Swarmcatcher. You are welcome.

This is misleading. The software will show more than 30fps but "ACTUAL" fps will remain at 30. 50D just isn't fast enough to go past 30 as far as I know. Perhaps there may be a way to do it at a lower resolution such as 480p or lower. The problem is that canon hardware dictates how fast the sensor can be read. Perhaps an idea would be to implement a crop mode hack that would essentially bring the sensor read area down to 1/2.3" or Four Thirds size. The less area the camera has to read from the sensor, the faster it could capture a frame. To do that you'd have re-write new firmware and that won't happen - from ML. (...unless you write new firmware with linux :-))

Hi there,
I'm trying to get RAW 1920x1080 30p in Crop Mode.
I have komputerbay professional 1000x 64GB card
I'm using RAW Video MLV
Camera captures 9 seconds then skips frame and stops (gets about 270 frames)
What do I do wrong?
Title: Re: Canon 50D
Post by: dlrpgmsvc on October 21, 2015, 09:09:18 AM
Select 23,9 fps so you obtain continuous full hd raw recording, otherwise you cannot keep 30fps for long.
Title: Re: Canon 50D
Post by: dlrpgmsvc on October 21, 2015, 09:10:12 AM
Beware: only in raw module, not mlv raw
Title: Re: Canon 50D
Post by: josepvm on October 21, 2015, 10:45:44 AM
With mlv you can get 1920x1080 continuous recording at 20 fps max. If you need higher frame rates you need to select a lower resolution, and upscale the recorded footage in post.

Thanks a lot.
A couple more questions.
1. I couldn't find a right way for framing in crop mode. It's just almost unpredictable.
2. When I run a 5 min benchmark, it shows around 50-51mb/s...   1920x1080 Crop Mode at RAW video (MLV) 69-71, at RAW 74-77  - is this normal? (could it be, if the card is not good?)
Title: Re: Canon 50D
Post by: EVZML on October 25, 2015, 03:51:27 PM
Short question:
Would it be possible, to record audio on 50D, by using a USB-Mic (MLV-Rec or H.264)?
If it's not possible right now - maybe it would be a good idea to develop something like this for the new firmware update?

I mean, the 50D is a really good video camera by using Magic Lantern Firmware (especially for it's low price), but the point for most people is the problem of missing audio recording functionality.
Title: Re: Canon 50D
Post by: dlrpgmsvc on October 25, 2015, 03:58:12 PM
Audio is better recorded by external rigs. Even if it would be possible (and it is not) this would lead to a much lower recording resolution and/or quality. If you want you can post this to the features requests thread but be prepared to be frozen almost instantly by the answers... ;-)

Thanks to everyone who helped develop this port. Amazing that it can add so many feature to this body. I'm still learning how to use Magic Lantern but really enjoy what I've played with so far on the 50D.

I actually went and sold my 70D because the 50D beats it in many categories. I was able to get not much less than I paid for a body that might lose value in the next year. Got some great photos with my 50D, interesting RAW videos, and think I can put the money towards a better use.

gothpugs, I first had to update my firmware to 1.0.9 per canon website.

After that I formatted CF card in camera, unzipped all files in ML downloaded zip to CF card, updated firmware from CF card and followed all camera onscreen instructions. It was very straightforward.

Bet it's because you rather use the CF slot than SD for longer recording times in larger aspect ratio, correct?

my 50d overheats just by sitting in liveview after 30 minute. I assume this is normal and once i install ml and start recording raw it won't last past 5 minutes. I was thinking of placing a cpu heatsink and a pc fan underneath it. I've heard some people use icepacks, i assume dry ice. Can anyone comment on ideas or experiences. if one had 2 bodies i don't believe 5 minutes of rest in between each one would be sufficient to not cool it .

Also, can you guys specify min pc requirements to edit raw? does one create offline edit then come back in lightroom and grade only the final edited footage?

Found a video talking about the A6000 overheating: https://www.youtube.com/watch?v=juO0Uojw8l8 (https://www.youtube.com/watch?v=juO0Uojw8l8)

The video shows how to install a 1mm thick silicone thermal pad from the eBay: http://www.ebay.com/itm/151681154470?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT (http://www.ebay.com/itm/151681154470?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT)

FYI: There is just about enough on the thermal pad to use for two cameras.

Why not try this out with the 50D? Purchased the pad and installed it. Seeing results that last for about a 45 - 50 minutes non-stop recording, with the camera starting at room temp, at the max non-cropped 16X9 resolution. It was 80 degrees when tested. I'm using a Komputerbay 128 GB 1066x card and a battery grip. (The grip may help keep heat out of the battery compartment.)

- - - - - - - - - - - - - - - - - -

Removing the back LCD panel and adding the thermal pad is quite simple on the 50D.

There are two screws on the bottom of the camera. One screw hidden behind the rubber pad by the "Zoom" buttons. Two screws on the side of the view finder (behind the eye cup). One screw that holds that focus adjustment for the viewfinder.

The back panel pops off and there are two ribbon cables that have quick-release attachments to the main board.

Entire process should take about 10 - 20 minutes to instal the thermal pad. It only requires a small Phillips screw driver and something to cut the 1mm thick thermal pad to the correct size. (** There are two main metal plates that protect the Digic 4 Processer and another group of electronics. I removed the shield on the Digic 4 Processor, there are two screws holding this plate in place. The second metal plate can't be removed without taking the camera further apart. Thinking it's not worth the time and hassle.

After 50 minutes, the the camera feels hot. Removing the lens releases a lot of heat. The LCD feels warm to the touch. Wondering if it helps to open/vent the side rubber ports covering the HDMI and other connections? Honestly, the camera, at this temp, doesn't handle well and needs to cool off.

Update for Camera Run Time with 1mm Thermal Pad:

Ran the camera for about 45 minutes... The temp stated it was at 48 degrees Celsius. However, the camera turned off and I could smell the electronics having heated up to a high temperature.

Shot 111 GB of footage at 1400 resolution at 24fps hoping to reach 128GB on a single record.

Don't expect to get 45 minutes out of the camera, even in 75 degree temperatures.Suggest something like 30 minutes, at most, then you better turn the camera off manually.

For the test I used a battery grip and had the rubber side opened to help the camera breath. Even still, the recording temps were way too hot.

I was shooting yesterday with my 50D RAW.
Somehow the camera decided to record the last two shoots only in h264 (1920 x 1080p) instead or ML-RAW.
I took the camera home. copy the files. And got ten RAW files.. but also two .mov files.
I put the card back in, film again. And the camera shoot RAW again. As it should.

I´m 100% sure that i did not change the RAW Settings while shooting. It was point and shoot (hit record)
I was NOT in the ML Menu. The settings was all the same.

Now i will load up the "file system" and have to check after every single shoot if the camera recorded RAW or a mov file.
Anyone else got this problem?

2. I don't see any options to enable raw video. Should there not be a M menu for loading modules?

@visiono,

Only nightlies have raw. It is recommended to use the latest to get all recent improvements. As frequently indicated, no ml is 100% "safe" but you won't find many (or any?) stories of actual damage done to date. Whichever version you decide to use, always thoroughly test it before using for anything important.

Post by: visiono on June 01, 2016, 08:01:55 PM
thanks. is anyone using the 50d in crop mode for raw video? I understand you hit crop + to go above the 1584x rez. It seems i can record 1920x in 2:67 aspect ratio but the preview is not right. How do you see your framing in crop mode on 50d ?  Also, even on non crop once i hit record the aspect ratio changes from 2:35 and i can't see any overlays only the MB/s counter and red rec icon.

I thought I'd check with other users before submitting a bug report. Is anyone else having problems with the last two nightlies? With the new files it seems to hang the camera for me when I format the camera. As usual it says "magic lantern restored :)" but then the new step "restarting camera" executes buts does not complete. The red and blue lights stay on and the camera hangs. It won't restart until I pull the batteries. I'm using a grip. I've tried it on 3 different Komputerbay cards all 1000x.

Does this Lua script (http://www.magiclantern.fm/forum/index.php?topic=17027) work for you?

Either this method of restarting the camera is not exactly correct, or something happens during format/restore that corrupts the DryOS state, causing improper shutdown. The above test should tell which is the case.

A similar test, for those who can compile ML - put this in "don't click me":

Code: [Select]
static void run_test()
{
    msleep(2000);
    int reboot = 0;
    prop_request_change(PROP_REBOOT, &reboot, 4);
}

This does the same test as the script linked above, but without Lua overhead.

Post by: a1ex on August 21, 2016, 09:52:06 PM
We have narrowed it down to dialog_redraw, and I guess it's related to a 50D quirk: unlike all other cameras, the 50D redraws its GUI continuously.

Here's a test anyone can run: load selftest.mo and run the redraw test. It's an infinite loop, and it may or may not be obvious whether it's actually running. If you run this test at the same time (in parallel) with the rectangle test, it will be obvious it's running, as the rectangles will disappear quickly.

While running this test, try to navigate Canon menus (it should not crash) and check whether the camera shuts down and restarts fine (without having to take the battery out).
Title: Re: Canon 50D
Post by: josepvm on August 22, 2016, 01:06:34 PM
Launching  the redraw test, that's what I see:

- The ML menu closes, Canon's normal status screen in photo mode appears. the blue led in liveview button blinks during several secons, and after that it stops blinking, so the redraw action starts. I can not see the effect of the redraw, because in this screen the 50D does not show any overlayed info (On a 500D doing the same test, I see the overlays blinking)
- I press the "menu" button, Canon menu appears, but the top icon raw, containing the taps to access every page in menu, is not shown, is all blank (this does not happen on 500D)
- When I move camera's main dial, the tabs start to show, but I only see two of them (the actually selected and the last one previously seen, the other icons seen before disappear when moving the dial away from them)
- I can come back to normal status screen half-pressing the shutter button, but I can't longer enter ML menu pressing trash button.
 - I can shut down the camera  normally with the power switch, no need to extract battery.

If I enter the "format" function in Canon menu, the camera hangs when rebooting after format, as usual. Having the redraw test active does not make any difference.

If I launch the rectangle test and then the redraw test, I do not see any difference on 50D respect launching only the rectangle text. The rectangles get erased quickly anyway, so I can see parts of the underlying normal status screen. This is different behaviour that in 500D, on this camera the rectangle test launched alone fills all the screen so I can't longer see the underlying Canon status screen.

Hello,

I have been reading through this thread looking for the best settings that the 50D can achieve. I currently have a 70D but the RAW recording is sort of limited (SD card write) as well as the occasional overheating/ERR70 messages.

I am now looking at picking up a secondhand 50D just for video.

What is the best resolution/FPS that can be achieved for RAW video? and how long would this record for? Taking into account any overheating?

Will any CF card rated 120mb/s be OK for this or tare there specific brands only?

Some of the RAW video tests I've seen posted look amazing.

Thanks!

Hi, I am new to the forum and a new owner of a mint condition 50D. As soon as I received the camera I installed ML. First I want to thank all of the contributors and testers who have made Raw video on the 50D possible. It is a beautiful image. But, there's always a but, when I first started using ML Raw, I had no issues whatsoever, everything worked fine. Then, out of nowhere, it started freezing up on me. At first I thought it was because I have global draw on while recording, so I switched it off, didn't change a thing. Then I thought it was because ALO kept enabling itself. Actually after the camera freezes, the only way to unfreeze it is to take the battery out. Then when back on and running, the camera does not recognize the raw module, or actually the module screen. It requires an on/off cycle for it to be recognized again. I finally figured out how to disable ALO and I was ready to go, but nope, it still freezes. My only assumption is temperature. When I initially turn on the camera, it registers at 30 degrees Celsius, I guess it seems okay, but by the second or third take, the camera is freezing every time I hit record. By then the temperature is floating around 45 degrees. Anyway, I could really use some help here, because I don't know if this is a settings issue or my camera is just running hot or what, but this is unusable as is. I read earlier in this thread, about a basic 2.3 version, is that version more stable, or are there any plans to create a very basic build that only has the most relevant of tweaks... 24p (23.976) exposure override, manual controls, Raw recording, and any other basic settings? Am not a technical person, so I'm not even sure that would help with the stability? I have fallen in love with the image coming out of the 50D Raw, but now it seems like I won't be able to use it, but now I'm already hooked and I can't go back to generic consumer 4K. Please help.

EDIT: Okay, so I decided to try and reformat the card and now it works fine. I apologize if this is a common fix that I wasn't aware of. But when this started to occur, the card (lexar 64gb 1066 card) was only about half full. Will this happen every time the card fills up, or was there just some kind of glitch that was fixed when I reformatted the card? Also, if I remember correctly, the problem occurred after I received a funky file that was pink and digitized... Could that have been the cause?
Title: Canon 50D - audio recording
Post by: doxa on September 21, 2016, 11:52:32 AM
I am planning to add audio recording to 50D by using a remote shutter and an audio recorder.
Pressing record on remote shutter would start video recording and audio recording.
For this you would need an on/off button to start/stop of audio device and the same for 50D through remote shutter.
ML cannot record/stop with remote shutter (ERR 99). It can only record. 50% of the problem is solved.
Is there any way to solve this issue ?

Another way is by using a follow focus solution ex. Aputure UFC-1S.
Dismantling of UFC-1S to get access to rec/stop button seems too much for this project.
The best solution is a ML workaround to stop video recording through remote shutter.

Title: 4Gb split files causing troube
Post by: natan069 on September 28, 2016, 11:17:31 PM
Hi guys!

I have a 50D and i´m having trouble with the 4gb limit.
What can I do to minimize problems related to this?

Fat32 formated with 64k sectors. 128gb Toshiba 1000x

When I try to convert the Raw files, the video plays ok until it reaches the split, then it freezes the image or show bugged footage, flickering.
Plays ok until 1:17, then it bugs.

I have to close Mlvproducer, open the file again but transcode lets say from 1:18 to 2:00, then I can watch the transcoded footage ok.

tried to convert to other formats, not worked too, same error.

EDIT:
I´m testing MLVrawviewer and it seems to be a MLVProducer problem.
Will test some more and update...

Quick question to those that use this camera. I've purchased a KB CF 1000x card that has a Crystal Disk Mark score of 132.4mb read and 108.6mb write, but that only translates into ~71mbs in camera. I've read through this form and done the things that were suggested to improve speed (reformat to 64kb), which gave me 10+mb through CDM, but I cannot get anywhere near the ~80mb I need to record non crop without FPS override.

For anyone that knows from experience, is getting a card with a vastly higher rating going to give me the +10mb write I need in camera, or am I at a permanent loss. I'm already almost at 2x the camera benchmark through my PC.

Some time ago I played around with an dual iso video branch, that is supposed to work on the 50D and the 5D Mark II. I don't know why but it does not work on my 50D so far.
https://bitbucket.org/tecgen/magic-lantern/branch/5D2-50D-dualiso-video#diff

The good news is, I am able to record dual iso RAW video by changing the CMOS[0] manually to a value of 8, 18 or 28. (See also my post in the dual iso for 5D2 thread http://www.magiclantern.fm/forum/index.php?topic=16854.msg171694#msg171694)

Here you can find a MLV of an 50D dual iso RAW video and a dual iso DNG file that was created by MLVFS.
https://www.dropbox.com/sh/w2wemk17d5x95fu/AAAosfOCYFDQM4SPvoL4WHuda?dl=0

Can anyone help us to put these things together? It seams simple to get dual iso RAW video working even on the good old 50D.

Quote from: a1ex link=topic=9852.msg171070#msg171070
Here's a test anyone can run: load selftest.mo and run the redraw test. It's an infinite loop, and it may or may not be obvious whether it's actually running. If you run this test at the same time (in parallel) with the rectangle test, it will be obvious it's running, as the rectangles will disappear quickly.

While running this test, try to navigate Canon menus (it should not crash) and check whether the camera shuts down and restarts fine (without having to take the battery out).


For those who like me struggle without newbie level detail:

Download the lua script from http://www.magiclantern.fm/forum/index.php?topic=17027
Save the Reb_Modu.lua script onto the card in the ML\SCRIPTS folder.
From Magic Lantern Modules menu enable lua to run on reboot.
Restart the camera.
Scroll down on the Modules menu and Reboot now appears at the bottom of the list. (works for me).
In ML/Modules enable selftest to run on reboot.
Restart the camera.
On Debug Menu scroll down to Self Tests. Use the Func button to select “redraw tests (infinite)”.

A1ex, sorry for the late reply. I'm on holiday today so have more time.

When I use the redraw tests I get four flashes from the blue LED. I can navigate to Canon menu and select format. The screen reads “magic lantern restored” and then the screen goes black and the camera hangs with the red and blue LEDs lit and I need to pull the battery.
I get the same outcome if I select rectangle test just after redraw test with the camera hanging with the red and blue LEDs lit and I need to pull the battery.

I hope that helps narrow things down.

Hi guys. I wonder if anyone know how to bypass the screen resizing to make it possible to use windows tablets as field monitors with EOSView?

"On 6D it works in photo and movie, same on 50D I think (just need to block LV resize when USB connected). 6D it does 30 or 24fps so you could in theory record it. I'm actually going to try monitoring over USB with my GPS/Tablet thing and my phone. I haven't tried recording yet but just turning on raw is fine."

Hello guys! I recently bought an eos 50D to replace my ooold eos 10d. A couple of weeks ago I installed magic lantern to it and it seems to run fine on the 50d. Full of expectations I did a few test shoots with it, which turned out fine and I brought it with me on vacation to do some video shooting. However coming home today and checking out the footage on my computer I was shocked at the strange "artifacts" I am getting. As far as I can tell it is not "moire" or "aliasing" as I have read is a common problem with the 50d. This is far worse, as if the footage is overly compressed or something (although it is filmed in 1920x1088 30fps). I guess it would be normal to suspect the memory card beeing too slow, however this one should be more then fast enought with a write speed of 120mbps?!

Can someone help me, or at least tell me what these weird "square" artifacts really are?

Best regards

Hi, I got a question I run a really ancient version of ML on my Camera (1.0.8-ml-2011Dec22) now my question is how is the update process. As I see it I first need to Update to Canon 1.0.9 Firmware then to the current ML version. Can I just update to the Canon Firmware straight from the ML or do I need to uninstall it, if so how do I uninstall it?

Thank you

Take a spare card (recommended 2-32 GByte) and format it using cardreader. Format it again using cam. Copy extracted Canon firmware 1.0.9 file to card and run firmware upgrade.
Insert your ML-enabled card into cardreader. Backup ML directory and all contents in root directory. Then delete all FIR files and autoexec.bin from card and delete ML directory, too.
Copy extracted nightly build content to card.
Insert card into cam and startup.

Does 5D2 have the same issue with cropped RAW video not being centered like 50D has? Does 5D2 has the same MLGrayscale preview mode, do all cameras have it?

Can the MLGrayscale preview in cropped mode (on the 50D or on all cameras) be made less ugly?
Can we scale the actual raw frame that is being recorded (in crop mode) to 50% (or 25%) and center it to available screen area? If the resultant preview frame resolution doesn't match the available screen area - crop or letterbox it but still center it to available screen area - this way it's still "close" to 100% frame coverage and there is less scaling distortion and no aspect ratio distortion - you can actually see what you are filming.
Wouldn't it be better like that?
I'm also wondering if what I've described above can be done NON-greyscale but proper LV colors.

Another question - what effects MLGreyscale preview performance? It started lagging recently (like less than 1fps), I don't think it was like that before.

I've been using an old nightly build for quite a while without major issues. Also recently picked up a new card(KB 128GB 1066x). On a recent shoot with a lot of long takes I've had a couple of seemingly corrupted files(besides the occasional skipped frame). That is to say: seemingly records fine, can preview in camera but when copying to a computer it won't let me(on mac the card is not recognised until the problematic clips have been deleted, on windows the specific file fails to copy while copying and card is ejected). Also tried dd entire card under linux with similar results. This seems to happen more on the new card than my older 32GB cards.
My questions are:
1) Has anyone noticed something similar and on what build was this? Did you manage to resolve this in any way? What can I do/provide to get to the bottom of this?
2) Is anyone shooting on a newer build for a while you are happy with(and you consider solid)?
3) Do you find mlv_rec(or another setting) to be more stable/less skipped frames?

Build: Nightly.2015.Nov15.50D109
Settings: Expo. override: on, GD: on, zebras, peaking, waveform, fps override: 23.976, RAW full sensor 16:9 max resolution using raw_rec

1 & 2 / First of all, I have to reccomend you to use the latest nightlies. I had more stable recordings by sticking to the latest nightlies.
When I had this problem (happened to me several times) I found out that the "big" corrupted files were in fact recording that stopped at the beggining that I had to stop by removing the battery. These files are actually almost empty but are reported with a wrong size on the CF card. May be wrong, but that is what I think.
3/ I use MLV_Rec more because the interface is more usable IMO. The latest MLV Lite is mor usable though. I'd reccomend both other the old raw_rec as MLV files are much easier to handle ;)

Well, I have those types of corrupt files too sometimes, but this looks like a different kind of corrution. The camera never indicates a problem or crashes, can review shot using MLV_play but cannot copy to computer(see details above).

I usually update ML as soon as I see an update available.
In the newer builds, both MLV_Lite (the old raw_rec updated) and MLV_rec record MLV files (can someone correct me if I'm wrong ?)
So no worries about that.

As there is development about new crop modes / lossless compression / 10/12bit recording I have to recommend you to update frequently ;)

The current "nightly" build still hangs my 50D when formatting the SD card. Requires the battery be pulled to turn off/restart camera. I know this is an old issue.

There used to be an older "stable" build that did not have this problem. However, I only see the nightly available on the download page.

An earlier post on this board made a reference to build 409 or earlier... looking at the available downloads, there it no "409" or similar. The naming conventions are all date based.

Where can I get the older version without the problem?
OR
Is there a workaround/solution for the crash on format issue? (Or does everyone simply remove their battery when formatting?)

Thank you. I'll give it a try.

edited - Now I see. The versions are listed down the side on that page. Based on the earlier post, I see that I need version 403 or earlier (not 409 and I originally typed).

I'm curious. If 403 (June 13, 2016) is the last build that doesn't freeze the camera on formatting, then the problem has existed for almost a year. Looks like there have been several updates since then. Is this a problem that can't be fixed? Does everyone using a more recent build simply remove the battery after they format?

Back again...

Perhaps I didn't ask the right question. I uninstalled the ML version from my camera. I then downloaded and installed the June 16, 2016 (#403) version, which I thought was supposed to fix the crash on format problem. It did not.

Can someone let me know which version of ML I can install that will not lock up the camera when formatting the SD card?

Thanks.

Not aware of this issue, then again, using a much much older build. Will try to reproduce and report back.

I'm not sure if we can catch Canon's debug messages during this lock-up, but let's try. You can use this build:

https://builds.magiclantern.fm/jenkins/job/startup-log/

It logs everything that happens in the first 30 seconds (while the LED blinks), then it saves a log file. If you can catch such a log, that covers the card formatting process and the lock-up, please upload it.

Whether the lock-up can be caught by this logging code or not, depends on whether DryOS is still alive after the crash (which I don't know yet).

These logs would also help me emulate the 50D in QEMU, btw.

Hello,

I have been reading through this thread looking for the best settings that the 50D can achieve. I currently have a 70D but the RAW recording is sort of limited (SD card write) as well as the occasional overheating/ERR70 messages.

I am now looking at picking up a secondhand 50D just for video.

What is the best resolution/FPS that can be achieved for RAW video? and how long would this record for? Taking into account any overheating?

Will any CF card rated 120mb/s be OK for this or tare there specific brands only?

Some of the RAW video tests I've seen posted look amazing.

Thanks!
See: https://docs.google.com/spreadsheets/d/16cgnRivbUv7nA9PUlCLmLdir3gXdIN3pqzCNAAybepc/edit#gid=5 for current capabilities. Can confirm those numbers with a good card. Best to buy a known good card, ratings don't mean much. If it needs to be cheap I've had good luck with 32gb 1000x KomputerBay cards.
Title: Re: Canon 50D
Post by: littlebobbytables on May 02, 2017, 11:46:21 AM
EDIT: Okay, so I decided to try and reformat the card and now it works fine. I apologize if this is a common fix that I wasn't aware of. But when this started to occur, the card (lexar 64gb 1066 card) was only about half full. Will this happen every time the card fills up, or was there just some kind of glitch that was fixed when I reformatted the card? Also, if I remember correctly, the problem occurred after I received a funky file that was pink and digitized... Could that have been the cause?
Might be that the card was not able to record fast enough before formatting. Formatting or erasing a card that's been used for a while can really help.

Here's the log file.

It's zipped and in DropBox. Can't see how to attach other than an image to a post in this forum.



edited to add: As expected the logging version also locks up the 50D after formatting a card. However, it also adds another issue. After the battery is removed, the camera will no longer start up from that card (removing and re-inserting the same card does not help). I need to insert a different CF card (which happens to be non-ML) and start up. After I shut down and re-insert the ML card, it will start up again.
Title: Re: Canon 50D
Post by: a1ex on May 02, 2017, 07:07:04 PM
Thanks. For some reason, the emulation is stuck in an infinite loop trying to "send LensBP data" to the MPU - can you get the same log without the lens attached?

edit: nevermind, got the GUI working in QEMU!!!

The shutdown process appears to run normally, as far as I can understand from it. The display appears to turn off, but the blue LED keeps blinking, according to the log. Is this what you are seeing?

For the second lock-up issue, try removing the battery and putting it back, rather than swapping cards.

Almost. After formatting the card, the camera attempts to restart. The display does turn off. At that point both the blue and red LEDs are solid (no blinking). Camera is completely unresponsive. "Off" switch does nothing. Battery must be removed and re-inserted.

Removing the battery shuts off camera (obviously). Re-inserting battery allows camera to start up normally.

This is all the "standard" freeze on format behavior I have experienced with all "nightly builds" I have tried.

Here is a log file from the May 6 build session.

https://www.dropbox.com/s/khu85t3qxr1asa7/dm-0000.log?dl=0

Using this build of ML, the camera still freezes after formatting the CF card. However, this time, only the red LED stays lit. The blue LED is not lit and does not flash.


EDITED TO ADD: The above behavior is what should be reflected in the log file.  Just tried this again (turn camera on, take a photo, format card). First time it worked. Card formatted, camera restarted and did not lock up. Tried it a third time-- camera locked up with both red and blue LED solid. Fourth try and camera locked up with no blue LED/solid Red LED.

It seems that if the startup log process is still happening, it locks with only the red LED. If I wait for the startup log process to be done (blue stops blinking) I lock up with both LEDs solid. Not sure how/why it didn't lock up that one time.

 :) Any idea is the cmos0 values can be checked into a build?
The ml iso only offer 1/2 stop Max as improvement. I would be Keen on trying dual iso to get the 14-15 stops


Some time ago I played around with an dual iso video branch, that is supposed to work on the 50D and the 5D Mark II. I don't know why but it does not work on my 50D so far.
https://bitbucket.org/tecgen/magic-lantern/branch/5D2-50D-dualiso-video#diff

The good news is, I am able to record dual iso RAW video by changing the CMOS[0] manually to a value of 8, 18 or 28. (See also my post in the dual iso for 5D2 thread http://www.magiclantern.fm/forum/index.php?topic=16854.msg171694#msg171694)

Here you can find a MLV of an 50D dual iso RAW video and a dual iso DNG file that was created by MLVFS.
https://www.dropbox.com/sh/w2wemk17d5x95fu/AAAosfOCYFDQM4SPvoL4WHuda?dl=0

Can anyone help us to put these things together? It seams simple to get dual iso RAW video working even on the good old 50D.

You need to mark the last changeset as bad and the older one as good:
https://stackoverflow.com/questions/3534107/what-is-mercurial-bisect-good-for
http://hgbook.red-bean.com/read/finding-and-fixing-mistakes.html

e.g.
Code: [Select]
hg up unified -C
hg bisect --reset
hg bisect --bad
hg up older_changeset -C
hg bisect --good

Then, it's best to recompile both ML and the affected module(s); "make zip" from platform/50D.109 should be fine.

The only change in the latest build was in the silent picture module (nothing changed on mlv_rec or ML core). You can check the previous build again - maybe something changed in your settings meanwhile?

The above error should disappear with "make clean" - not sure why it happens though.

Yes you have crop mode. You can do full frame continuous (1584x1056).
Check the calculator http://rawcalculator.bitballoon.com/calculator_desktop (http://rawcalculator.bitballoon.com/calculator_desktop) to check the maximum resolution in crop mode for your wanted aspect ratio ;)  (2.35:1 1920x818 is ok)
Compared to your 5D3, you'll be loosing 10-12bit raw and compressed raw (plus the 50D is not that stable if you want to record a lot in warm environments)

I've never had an issue with raw on the 50D - although haven't tried recording for longer than 2 minutes. H.264 has given me some reliability issues though. I also use a CF Sandisk 64GB Extreme Pro 160MB/s

I like filming with the raw crop mode (1x1). However even with the preview option set to "Canon" (i.e. normal liveview x5 zoom framing), the display turns to grayscale as soon as I press record, which isn't bad (it's nicer than the slow framerate preview you get with the "ML Grayscale" setting), but it's a bit hard to use if trying to focus manually during recording. Wondering if anyone has been able to get round this issue? I've tried various nightly builds and all the menu settings I could think of.

Before recording - crop liveview in colour: 
(https://thumb.ibb.co/dxZ7tb/1_Before_Recording.jpg) (https://ibb.co/dxZ7tb)


During recording - turns to grayscale:
(https://thumb.ibb.co/fwdveG/2_Recording.jpg) (https://ibb.co/fwdveG)


Also I use lenses with image stabilisation. and as far as I know on the 50D the only way to activate IS whilst recording video is to keep the shutter half pressed continuously whilst recording, without letting go. However, as soon as I half press the shutter whilst filming in crop mode, the display turns pink (again with the preview option set to "Canon").

Shutter half or fully pressed, pink liveview:

You can enable "Sticky half-shutter" setting which is located in Prefs->Misc key setting.

But in this case you need to start rec on, then half-press shutter once and you are good to go.
In order to stop rec, you need half-press first and then actually stop recording.

Feels tricky, but it is worth it, especially in combination with any gimbal.

Thanks I really appreciate that - it works very well for me, and makes the camera a lot easier to use!

Now just need to understand if it's possible to shoot in 1x1 crop mode without liveview going greyscale when hitting record, and pink when pressing the shutter button to activate IS. Does this happen to anyone else?

Have you disabled Canon's original GUI?
Blue flicker is looks like zebras on under-exposed areas, while the lower one is looks like a some sort of conflict between Magic Lantern GUI and Canon GUI.

I remember an old build where dual ISO mode was enabled for video. Also, 2.5K in crop mode is possible with 10-bit/12-bit mode - hopefully that will be done soon-ish. No moire in crop mode...

I've just tested this build - works very well. Thanks so much for this dfort. In crop mode I'm now able to record at the max allowable res of 1984x1078 continuously (or nearly so) in 12 bit raw. It's fully continuous in 10 bit.

As I mentioned in my post above (21st Jan), it's a shame I'm getting a grayscale preview in crop mode once I hit record (which turns pink when half pressing the shutter button). This is with "Canon" selected under preview options. At least it's a real-time preview that isn't pixelated like the other preview options. However I'm wondering if anyone else has this issue too, since I haven't seen it discussed anywhere. Maybe it's just my camera that has a problem?

Known issue on very old models (5D2, 50D and 500D). Possibly also 7D.

Last time I've looked into it (some years ago), I remember having to choose between clean recorded image (without bad pixels or other artifacts) and good preview. Clean recorded image resulted in pink Canon preview for some unknown reason. Made it grayscale as it looked nicer than pink.

Meanwhile, I think most raw converters got the ability to fix bad pixels, so this might be worth revisiting.

Thanks very much for confirming this issue, that's useful to know it's also a problem on the other oldest models. Wish I could help look into it but don't have any coding knowledge. Would be amazing to try fixing it since crop mode on the 50D is incredible, especially now that 12 or 10 bit recording is possible.

The feedback I got was that 10bit is working on the 50D. The test build is still on my downloads page.

Hi all!
I´ve installed and tested this 10 and 12 bit version of RAW MLV and have been some problems with it.
One of them and the most important that I remember right now, is when I´m traying to change the ISO values, the camera inmediately locks up and the blue light that activates the LV appears. Then I´ve to reset the camera.
When I reset and try again, the ISO values changes , then stops and again , when I try to change it, the camera locks up.
Any one have this problem on this version?
Thanks in advance,
Asier.

First I heard of these issues. I was getting reports like this:

https://www.magiclantern.fm/forum/index.php?topic=5601.msg194390#msg194390

Not sure what is going on in your case. I'm able to run the 50D in QEMU with the firmware dump that I've got.

Hi dfort!
Thanks for your input!
I,ve just tryed to "unpick" the "crop_rec" module to to avoid my camera start up with it for the next time.
The result is no errors on the screen. All the rest of the available modules are successfully loaded or that what it seems. :)
I´ve to check again for the ISO problem I got on this version that was locking up my camera.
I´ll let you know how it is going.
Regards and thanks,
Asier.

Oh wait, you're using the crop_rec module? That isn't working on the 50D yet. No wonder you're getting errors. The "crop" others are talking about is when you get into zoom mode using the magnifying glass button.

Post by: Asiertxu on April 12, 2018, 12:54:58 AM
Hello Dan!
Yes, I seems that the "crop" recording module makes the camera start with error in all the other modules.
Even thougth ,there still have "locks" when traying to change ISO values when the camera is with the LV activated.
I´ve discovered today that, when need to change the ISO and don´t want my camera lock up, I temporaliy go out from the live view mode, then I change ISO
with the LCD buttons and the wheel, then I active the live view again. This way the camera does not lock up and the new ISO value is ready to use.
This is a bit anoying thin but it looks to work for the moment. ;-)
Thanks for your help Dan.
Best regards,
Asier.

By the way, I realized that I had to disable the Crop Module because I had readen in the link that you provided me that some people had been having problems with them module and therefore I tested without it, so I had no problems anymore when starting my camera after that :-).
Best regards,
Asier.

Ok, first time ML user here on a second hand bought 50D.
What strikes me is that there no "One page, all settings, best settings, user guide" for this camera.
So i look for multiple sites and fora to get my info and do some trail and error work.

I used two version of ML on my Canon 50D with Sandisk Extreme 32GB 120MB/s card.
1- magiclantern-Nightly.2018Feb04.50D109 - which works fine but does not give the 10/12/14bit option and i cannot seem to set 1/48 shutter.
2- raw_video_10bit_12bit_LVState-wip.2018Feb04.50D109 - which gives me bad video (MlRawViewer_1_3_3_win32 crashes trying to watch the MLV files and MLV Converter 1.9.2 gives me pink pixelated DNG files).

What i want is continuous 1920 x *** 23.976 2.35:1 RAW video. Prefered without crop.
I know it's not possible to do 1920 x *** without crop on  the 50D.

Is there a page for all this info?
Title: Re: Canon 50D
Post by: dfort on April 18, 2018, 05:21:04 PM
@Gutje - That 10bit/12bit build is highly experimental. We haven't figured out reduced bit depth, lossless compression or increased image sizes on that camera yet.

Not that 1920x1080 without crop on the 50D isn't possible. The camera actually shoots a slightly smaller image and it needs to be resized in post. When shooting H.264 it is resized in camera. The only ML supported camera that can shoot 1920x1080 non-crop raw video is the 5D3.

There was an attempt a while back to put all the information you need in one topic. It is a little outdated now:

Ok, so i after a fair bit of searching and back and forth from links i thought it would probably be best just to ask.

I have just uninstalled very old ML and reinstalled the current 2018 build. before everything was fine, but now i am only getting 640x480 30fps or OFF option. What i read was to select the RAW option from the video menu to get the other option, but i don't have that option (RAW). am i missing something else i should be downloading? Is it right in front of me haha. Hopefully someone can point me in right direction. :)

but now i am only getting 640x480 30fps or OFF option

Hi, very new to ML here but hope I can help. Do you mean the h264 video? As in the one that says 'movie record' under the movie tab? Have you tried pressing the func. button?




but i don't have that option (RAW). am i missing something else i should be downloading? Is it right in front of me haha. Hopefully someone can point me in right direction. :)

To enable raw just go to the tab that has 4 squares and then enable 'mlv_lite', 'mlv_play', 'mlv_rec', restart then it'll be there, hope it helps!




Now, I've really tried to look up as much as I can but I don't think my issues are mentioned that much:

So, about 50D's raw in general. During raw recording, are you able to adjust exposure settings using camera dials, i.e. aperture, shutter, ISO at all? If so, could someone kindly let me know how to? I believe the option of 'gradual exposure' means it does but I just couldn't find a lot of information online about exposure during raw recording.

Also, does ML video function have continuous auto-exposure function? As in Av or Tv equivalent for video? It is mainly to move between scenes that are of different exposure in one take? Do I have to use lenses with physical aperture ring or fitted with ND filter?

So, the main problem I have is with exposure, if you guys can direct me to some good source, much is appreciated! Also, is 50D consider a good working raw video camera at this point? I mean am I suppose to expect other cameras running ML to be similar to 50D in terms of working condition?


Let me know if you need more info. Many, many thanks!




Some function i turned on during my raw video take:
Expo. Override     - to use 1/48?
ExpSim                - for histogram
Histogram            - for exposure checking
FPS override         - 23.976

Raw                     
- Res.: 1568x668; Ratio: 2.35x1;
- Preview options: ML Grayscale (correct me but 50Ds have issue with pink preview in other modes?)
- Use SRM Job Memory: ON
- Extra hacks: ON
- Buffer Fill: 4

Kill Canon Gui - Idle/Menus


*edit*
- removed question on ISO issue, just wanna focus on finding out if real time exposure change is possible.
- tried to use physical dials and ML's Arrow/SET shortcuts to adjust, none works...

Any help is much appreciated!!

Hi, about the 10/12 bit recording, is it this one: raw_video_10bit_12bit_LVState-wip.2018Feb04.50D109.zip ?

I've tried and the recording seems to go smoothly but when reviewing, the images are corrupted?

Seemingly quite a few got successful with 10bit, so can one go higher than 1584*xxx (the max on 14bit) with the extra headroom on 10/12bit or is it the same work in progress to make 4k capable on these newly compatible 10/12bit cam?

Either mlv_rec or mlv_lite but not both at the same time  , what app did you use to extract Cdng ?
If on Windows MLVProducer: [v3200] (https://www.magiclantern.fm/forum/index.php?topic=15271.msg203505#msg203505)(It's more then just a app to extract Cdng's it' a Grading app also) is the very best app here on the forum nothing even came's  close . It supports all the latest magic lantern changes and if you are on a MAC you still run MLVProducer App  on Mac with Wine .
download for http://wineskin.urgesoftware.com/tiki-index.php , you need this first then follow the instruction here  (https://www.magiclantern.fm/forum/index.php?topic=15271.msg151403#msg151403)  , I've ran this on my MacPro5.1 , so i know it works . After that  MLVFS (https://www.magiclantern.fm/forum/index.php?topic=13152.msg127218#msg127218)  is the next best app just to extract Cdng's

I tested this build  "raw_video_10bit_12bit_LVState-wip.2018Feb04.50D109.zip"  on my 50D and with 10bit video recording. It is working, I only got 16GB Sandisk card with 30MB/s so I can't to much of the stability need to get hold on a bigger and faster CF card. But it seems that this build is okay on my 50D.

Opened up the MLV file with MLVProducer as reddeercity mentioned, and there is no corrupted frames in the file.

Hey, I was using MLV Converter 1.9.2, found it from one of the 'get started guide' in the forum and since it was getting okay with 14 bit MLV files.

Anyway, tried MLV producer and you are such a life saviour!!!! THANK YOU SO SO MUCH.

However, there seems to be an issue with video shifting/ jerking at only the 1/3 section from the bottom part. A user with 50d reported something similar before in the 10/12 bit development forum.

video shifting example:
https://drive.google.com/open?id=1IenGoF4avcovV19xCDhtfQXLbW2zKf_1

Problem occurs regardless:
- 5x magnification mode or full frame mode
- any resolution
- with or without mlv_play module on (heard that 7d has 'earthquake' footage if video review is turned on?)
- 10 or 12 bit
- mlv_lite or mlv_rec

settings:
expo. override: on
global draw: histogram on
fps override: 23.976
preview: grayscale
use srm memory: on
small hacks: on

OHHH how a great discovery! During this writing, I realise that if camera is fitted on a tripod, meaning no camera movements, the shifting will not appear! So it only happens when the camera is moving!

Once again, thank you for all the help :D

I took a quick check with my 50D, got the same thing as the posted videoclip,  looks almost identical.  Some kind of strange tearing issue, I tested it with 1280x720 and 10bit, write speeds about 26 MB/s so my 30MB/s card should be fast enough for this.

mlv_lite

I was hunting this 10/12/14bit for full resolution silent pictures. Would have been nice with the option to get 10 or 12 bit to save space when taking a few thousand pictures to digitize old Super 8 films :-). Don't want to move 700-800 Gb over Flashair card from Toshiba but seems that this or the WFT-E3 is the only option to access the files on the memory card while the camera is taking pictures.

Hello! I'm brand new to ML and the Canon 50D in general. My question is will autofocus during video work with this camera and ML?

Additionally, I am wondering what lens people recommend for taking video with ML and the 50D? I'm looking for a macro lense or wide angle - something like 11 - 50mm...
Title: Re: Canon 50D
Post by: r_non on July 18, 2018, 01:51:10 AM
Hi, welcome to the community and great choice to start ML with the 50D!

Personally, I wouldn't bother with autofocus in video mode just because with DSLRs, they simply don't have the capability to do smooth focus pull (assuming that's what you intended to do), unless you have Canon's dual pixel af (70D). Anyway, as far as I have tried, you can do autofocus, albeit only in one-shot af, meaning it can't do continuous af. The single af is handy to obtain focus of a scene before recording though it can be quite a bit slower compared to simply zooming in and focusing manually.

Perhaps you're wondering how to af in video, in that case use the 'AF-ON' button on the back. Have fun!

[edit] -additional replies
A good lens to start with is probably a wide lens so you have the freedom to use it in crop mode as well.

I'm a newby on shooting film with the 50D.
Shooting a movie with ML works perfect in the 1920x1080 mode 30fps (and also in the 640x480 mode).

But when I activate the MLV V 2.0
and change the raw video (MLV) settings to:
1280x640.
Aspect ratio: 2:1 (I like the cinematic ambiance)

Then the recorded movie is heavily underexposed. (I use faasoft video converter)
And the color is much to green.

What am I missing here?
In normal movie mode, all works perfect.
In MLV mode, the recording is very dark and green.

Try to convert your footage with this MLVApp (https://www.magiclantern.fm/forum/index.php?topic=20025.0). Can you give small MLV sample? You can trim it with MLVApp also.

Also, when I go into live mode, the info on the bottom of the screen is flickering.

Would someone please point me to a tutorial or document to set up to do only a basic shoot while I'm learning about the other features/settings?

Hi there. I don't think you'll find anything specific to video in the Canon 50D menus about video, as the 50D isn't supposed to shoot video. However, in the ML menus, under the 'movie camera' symbol you can turn video recording on and off - enable it here. Then select live preview mode (the button above the screen that turns on live preview), then if you press the button in the middle of the control wheel on the back, you can start and stop recording video. Once you can do that, you can play with all the other settings, which are explained in the ML menu.

I've got quite a lot of ML video from my 50D, recorded at 23.976fps. Its metadata reports it is 30fps (as noted elsewhere).
If I put it into my NLE (Lightworks) and slow it down to 80% normal speed, the NLE does this by inserting extra (copy) frames once in a while, which is a bit clunky. If I use FFMPEG to re-label it as 24fps (near enough!), it only seems to be able to do this by re-encoding, which given that these are lossy codecs is, again, a bit clunky - not to mention time consuming.
Has anyone figured out how to just change the appropriate metadata in the ML output so it is correctly labelled as 23.976fps? This mis-labelling by ML is proving to be a very irritating bug!

In premiere you can 'interpret' the footage to be whatever framerate you want.

If you convert your ML raw files with one of the available free softwares you could also convert it to a DNG sequence and import it that way. In After Effects you can select a default fps for importing image sequences for example.

Alternatively you could convert it to a prores file with MLRawViewer prior to importing in your NLE.

Just pick up a 50D used body from my canon camera store with 90 days warranty ($225 usd) , had to updated canon firm to 1.09v. from 1.03
only 21k shutter , looks like new  :) Tested magiclantern-raw_video_10bit_12bit.2019Mar24.50D109 everything ok so far , 10,12bit works great.
Even made the card bootable with the ML"FIR" though canon menu .
Very nice raw video images .

I plan on porting the 3k/UHD crop_rec from the 5D2 to the 50D along with (hopefuly lossless compression & CF Card over clocking)
being the 50D is very close to 5D2 , but the sensor seem to run at 28Mhz instead of 24Mhz like the 5D2 .

has the correct reading but ML report a different thing e.g. 100ISO . Using mlv_rec .

Can any other 50D user confirm this or not or is this how it is ?
Quick check using lua_fix (both mlv_lite and mlv_rec) by changing ISO in ML menu I get correct values in top lcd and photo mode, but I get the value doubled in ML info bar while using LV.

Same happens if I use top buttons to change ISO.

@reddeercity thanks for looking at 50d. Hopefully the compression module gets ported to raw_video_10bit_12bit_LVState
50d has less moire than 7d and 5dm2 so lots of potential..
