Canon 50D

[lionelp]

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?

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.

Simplified installer, not tested: http://a1ex.magiclantern.fm/bleeding-edge/50D_109.fir

If it works, I'll include it in the nightly builds.

Seems to work fine with both installing and uninstalling.

Great, nightly updated.

May be a good idea to check 64GB and 128GB cards too.

My largest card is 32 GB, so someone else will have to do that testing.

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.

Take a look here. Is that what you are talking about? If so there's a solution.

What about (true) pink frame corruption while recording with external HDMI monitor? Does anyone get any? Solution?

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.

Thanks

This may give some hints: http://www.magiclantern.fm/forum/index.php?topic=9262.msg105069#msg105069

I have asked a question in that thread, and if anyone can answer it, I can provide a fix.

@far.in.out That fixed it, thank you!

@rguk Would have to try if I get the same behavior. Will report back asap.

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

[ninurta]

thanks a lot

As i understood, i will not be able to see the real angle of view in crop mode?

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 ) 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.
