I've finished a (small) complete project, shooting RAW on the Canon 5D2!

Here's my report: http://crewofone.com/2013/canon-5d2-raw-vs-h264-in-real-world-production/

Here's the BTS video.

Here's the BTS video.

Here's my comparison of RAW & H264 on the 5D2. I used the Adobe Camera RAW utility in Photoshop to process the DNG files, and basically tried to maximize detail, rather than grade for aesthetics.

More details here: http://5dfilmmaking.com/05/testing-the-5d2-raw-vs-h264/

Canon 5D Mark II
Canon 24-70, Sigma 12-24
Magic Lantern Build May 15 & May 16

CF: Lexar 1000x 16GB

Nice! How did you process your RAW files?

rs555 ... Here's the step-by-step sequence of how I did it. Not sure it's the best way, but it does seem to be the easiest way: http://5dfilmmaking.com/?p=62

And, I was able to shoot this, so it seemed to work. I had to manually repair the footers on files shot with the May 16 build (thanks, a.d. for the help on that!), and RAW2DNG rejects any file over 2 GB, but it's still pretty darn cool.

a.d. ... I think I figured it out! Here's the footer that works for a 23.976 file.

a.d. - The good news is that the new patch of code resulted in non-corrupt files! The bad news is that it's still 29.97, which is giving a roll to the footage. All I need to do is get it to 23.976, and it'll be golden.

Thanks so much!

a.d., I'm opening the DNG files in Photoshop CS6. I've been working with the May 15 build, and (almost) all those files are fine. The lv_rec failure files were recorded with the May 16 build. I'll try this different footer and see if that makes a difference.

Thanks again for the help!

A.D. Appreciate the footer for my corrupted files, however, it seems to convert to 30fps @ 1880x720, and my footage is 25fps 1880x540, causing the frames to 'roll'. Is there anything I can change to convert to 25fps? Also, I'm unsure of where exactly in the code the footer should start, since the code seems to shift around a bit (I'm a noob).

a.d., Thank you for the help ... It definitely solves the RAW2DNG acceptance issue! Like the other users, though, I'm finding that the resulting DNG files consist of nothing but corrupted images. Also, the source file was recorded at 23.976 fps, but this footer makes a 29.97 fps file. We're so close ... Any more advice?

Many thanks again!

Thanks a.d. for this info! It sounds awesome ... But I tried it, and it doesn't seem to help.

BTW, I did press the stop button on all the files I'm trying to fix, so there is some code very similar to this footer already. Here's what I have:

When I replace the last four lines with the code you provided, the file still gets the LV_REC error in RAW2DNG. Anything else we can try??

[Still Frame Duration: 1 Frame]

Great tip about Compressor, budafilms!

For those who don't have Compressor, here's an alternate method:

- Use Adobe Camera Raw (within Photoshop) to open DNG and save as TIF sequence
- Within FCP or Premiere: Settings -> General -> Still Frame Duration: 1 Frame
- Drag and drop TIF sequence folders onto sequence
- Export as preferred flavor of ProRes, then re-import

I used last night's build, and then spent the whole morning carefully shooting lovely RAW vs. H264 comparison footage. I also got the pink screen during magnification, but it wasn't a big deal.

What WAS a big deal was once I got the footage home, and raw2dng gave me the "ain't lv_rec" error on all the files recorded at 1888x720 (I had one file at 1280x720 which did work).

If all that's missing from the files is a snippet of code, is there a way to manually append it? Or, better yet, some kind of patch that can be run? I was quite pleased with the footage, and if there's a way to use it, I'd greatly appreciate hearing about it.

A previous comment mentioned that the  "lv_rec" error results from a missing file footer ... Is that correct? More to the point, is there anyway to fix this manually? I spent the whole morning carefully shooting lovely RAW vs. H264 comparison footage, and when raw2dng rejected the files, it was rather disappointing.

I understand all the usual caveats about Magic Lantern and testing before shooting, but if there were a way to manually fix these files, I would greatly appreciate hearing about it!
