Where did you buy your cards?  If it was from Ebay or the like then you might have fake ones.

Obviously we all have the same camera and I also have a San Disk Extreme 45 MB/s class 10 64 gig and I can record 1280 x 720 without a problem.  I purchased my card from Amazon so I know it is legit.

Amazon for me too.

Hi all,

Well, I am ready to take the heat for being naive on this. 

This weekend I finally had a chance to play and wanted to do a full minute of raw and blend in surround sound (new recorder  .  Up until now I have been doing 10 sec clips.  Unfortunately I could not do continuous raw recording at 1280 x 720 at 16:9.

The message at the bottom says 36.8 MB/s  is needed (yellow text). I get about 700 frames before it stops.  If I change settings to 1152x648 16:9 or change the aspect ratio of the 1280 I can get the "green" continuous recording, which is obviously lower that the 720p. 

I believe I have the camera settings ok unless someone can advise.  I have two cards.  One is a SanDisk Extreme 80mb/s 8 gig class 10 (I got this before I realized this was over kill for the T4i) and a San Disk Extreme 45 MB/s class 10 64 gig.  Neither works for continuous raw recording at 1280 x 720 at 16:9. 

So is my camera a lemon or have I missed something?

I appreciate any insights.

Maybe depending on the issue you are having. 
Follow this thread:

Thanks,

Actually I was not having issues (have t4i) but see that advances in PDR etc have developed from the link you provided.  Somewhere it would be great to have a master forum with links to all important app udates and  workflows.  There is alot happening and one needs to find the time to monitor all of the sites.

So I assume your answer is that the software in the camera can work better with these apps.

Anyway thanks again for your help.

Hi,

On the change log for the new nightly changes to cr2hdr and raw2dng are mentioned.  Does this mean there are new versions of these apps out there somewhere or that the software in the camera allows them to do better things?

Sorry if this is a naïve question.

dave

Yup a problem and there is good info under there.  However, I believe this is on of the issues mentioned on the first post that is difficult to address.  I may be wrong but I think this is right.

He meant ISO as DUAL ISO

Would not dual iso also win because it makes integrating externally recorded sound possible?  I use PowerDirector a lot and found a very nice way of integrating sound.  Will play with raw and dual iso this weekend.

[sometimes the display does not turn on]

My 650D is with a strange symptom for a couple of weeks: When I turn on the camera, sometimes the display does not turn on. Everything works (flash, autofocus, shutter, photo, etc.), but the display just does not turn on. But after about 30 seconds (this may vary), the display turns on and no longer fails.

It also happens without card in SD slot (In other words: without Magic Lantern). I've reinstalled the official firmware, I already removed the magic lantern (turned off the bootflag), and the problem continues.

That does NOT seem to be a hardware failure, it seems to be something abnormal in boot.

Is anyone else having this problem?

Yup I have that problem.  Two things that I noticed that explains it sometimes: 1) I have the eye piece extender and sometimes it moves up on its track and partially blocks the sensor. 2) when it is really dark.  But that does not explain all the occurrences and why I do not get the play back image after taking a shoot sometimes.  I know this is off topic here but thought I would say you are not alone .

dave

Presumably you're talking about recording movies because you mentioned needing it to stay at 60 in an earlier post. If so, I strongly recommend you either check your answer to a1ex's question or read page 170 if you have the English manual.

thank you

Ever tried to use your camera without ML?

Yes of course thanks for asking.  Just learning the behavior of ML for video as I was an early adopter with the T2i but mainly used the image functions for things like hdr.  Now raw video is interesting and have messed all weekend doing much of the same as reported here (trying different resolutions, comparing to the Canon MOV video.)  Nothing new to report except my work flow is:

PDR on the raw file
Extract to dngs
Used Bridge to bring into PS6
Edit in PS6 and save to TIF
Use either QuickTime or PS6 to render movie. 

So all is ok, really.

dave

ML doesn't disable or change the functionality of the canon settings, it simply adds extra features. Your issues seem to be you don't know the camera well enough, i'd suggest reading the manual. I use M all the time but I know three are modes that let you control just one setting like Tv mode I believe is shutter priority, you set shutter speed camera sets iso and aperture. I really suggest looking in the manual a this really isn't ML related.

My canon

I will be polite    in my answer.  My canon cameras go back to the 20D, in terms of digital.  I know my camera, including being an early beta tester for Camera Raw. (added the camera raw part as a mod) 

My point is that in TV mode the speed should be fixed as it is with the straight canon software.  When shooting ML raw, the TV values on my camera change along with the iso and will not remain fixed.  Only in the M settings does TV values stay fixed.  So I was wondering if this is what I should be experiencing when shooting raw.

dave

all,

In addition to the iso comments (can I control) and problems with manual (may have solved) I just noticed that in TV mode when shooting the TV does not stay at 60, which we need.  So is my camera working right or do we need to to M mode at all times?

dave

I think I answered my question.  M at all times I guess.

Hi all,

two questions

1.  It seems that to manually control ISO you need to be on "M" as any other setting is auto ISO and I can not seem to turn that off.  Is this correct?
2.  Has anyone tried integrating audio into footage?  I assume that one would have to record audio on an independent device and then integrate in software.  Is this correct?  Also if it is it would be interesting if that along with the raw recording, a separate audio recording could be made.

Thanks in advance,

dave

Hi all,

I assume the answers to my questions are yes to both.  I can not change ISO in any other  settings for video raw other than "M".  However when put the camera into "M" the image cycles from light to dark.  Do you know if this is normal?

I feel like using higher bitrate cards gives you more "headroom" I suppose. To me, it just feels a little safer having twice as much bitrate available, just in case. That way, any bottlenecks are for sure the camera and not the card.

sounds reasonable

update:  PS done with your analyses yet ?

I'm back from vacation everyone!

I'm planning on compiling a whole mess of tests, benchmarks, and other various checks for the latest ML release. However, I'm currently waiting on a new charger for my T4i. My stock charger was stolen from me while on vacation, and I just used up the last of my remaining juice today.

I'm planning on doing:
-RAW resoultion tests w/ SanDisk Extreme 95Mb/s'
-RAW Pinkdotremover Tests
-Card Reader Benchmarks (using my entire card collection)
-RAW quality tests (sharpness, color, etc)
-A full short shot at the highest continuous resolution.

If you've got any additional requests just let me know and I'll add them in.

Wow this sounds truly great.  You vacation like me .  So just got an 8 gig 80 mb/s card for grins.   Does not seem to make any diff versus my 45.  My thinking is that here it has been said that above 45 does not make a difference because our cam can not go that high.  Seems to be true but if you have different results I am realllly interested.  Looking forward to your great work.

dave

The 14xx resolution was 1:2.35 not 16:9. 1472x838 is likely too high for continuous recording

gotcha

Sure, and you're lucky : I've timed most of the process !

Precisely, I've shot 11min12sec of RAW at 1476x626 (16 251 frames@24fps), for about 25GB on the memory card.

- The raw2cinema DNG (using RAW Magic on osx) took me 12min21sec (I ran the process directly from the rushes on the memory card and sets the output on the hardrive). Output 28GB of DNG (not 25 due to the 14bits > 16bits conforming I guess).
- PinkDotRemover tooks 34min44 (And gives me another 28GB of dots-free DNG). I used search expression (which I don't remember sorry) to selects all DNG without initial underscore (_) and delete them in order to keep only the dots free DNG.
- Finally, After Effects exports all rushes in uncompressed 8bit color-graded videos within 2h10 (Output : 39.7GB, always in 1476x626).

So globally, processing a RAW file from .RAW to 8bit video takes 15min for 1 minutes of shooting.

I haven't timed the final editing process (done with Premiere pro), but it was fast as all rushes were already processed in uncompressed 8 bits videos.

Got my cam.   Interesting, I do not have the aspect ratio you used nor do I have 1476.  I have 1472x828 at 16:9 but on my 45 45b/s card, I can not get continuous frames using this.  Also 20 sec gets my about 1 gig file size so not clear of diff with your file size.  Any other setting you did?  Sorry if these observations are too rookie like.  I am just really starting to learn about the video aspect of our camera.

dsagilles,

Thank you so much.  This is really interesting both in terms of time and file sizes and about what I have been thinking.  I only have been doing something like 20 sec clips so far at 720P.  Lots of experimentation yet.  I have some ideas about integration audio back in from an independent recording.

dave

Which difference?
1280*720=0,9216mp

sorry not complete I was thinking compared to 1080P

Hi all,

Messing with raw this weekend.  One thing that really attracted me to raw was some of the videos that showed the increases in sharpness (as well as other edits like white balance.  My attempts so far do not have the extra sharpness.  I probably need more practice, but I wonder about the 1280 x 720 size.  When I bring the dng into PS6 it comes in as 0.9 mp / 300 ppi and wonder if that is what the difference is. 

dave

Here is a video shot in RAW 1476x626 with ML alpha from last july (not the latest build so, I'll test the RAW from earlier versions soon).

All infos are in the video description.

Very nice,

Can I ask how long it took you to work through the process from extracting to remove dots etc, to final film?

Thanks

dave

This would be better answered in a post processing workflow thread.  It has the advantage that all ML RAW video users will be able to give answers.  In the post processing of RAW video, it has more to do with your platform (Win/Lin/Mac) and tools.  You might want to start with the below thread and check out the other threads in Post Processing Workflow section.

http://www.magiclantern.fm/forum/index.php?topic=5404.275

Thank you I will do that.  Just looking for help.  We also have the pink dot problem to deal with.

Just to mention, I can reassemble in PS6 and QuickTime. 

dave

Well, I'm gone a day and mightily confused by what some folks are saying! Not getting full 720p, then getting it? Haha okay. Upload the results people! I look forward to seeing everyone's work.

For me I reloaded ML and finally I had 720.  Something was wrong somewhere or ass Walter said "fishy"

All,

What you you using to recompile the files into video?  Virtual Dub?

Thanks
