Magic Lantern enables 14-bit RAW CinemaDNG on 5D

Looks like Thomas Worth updated RAWMagic for those interested in this workflow but can't follow:

http://www.magiclantern.fm/forum/index.php?topic=6218.50

Changes:
+ You can now force a camera model to be written to the DNGs. The only options right now are 5D MkIII, 5D MkII and 50D.
+ Fixed a coding mistake that disabled the ability to delete selected items

+ FPS display is now correct
+ 5D Mark II footage now works
+ Vertical stripes should now be fixed in most cases (still under investigation)
+ Ability to cancel the conversion

Beyond the ML teams hack itself, what Thomas has done is just as important to working with MK3/2/HDslr raw workflow. What he has done and given you guys (FOR FREE) is huge huge huge. Later tonight I'm gonna try and contact him and see if I can donate some $'s for his efforts. Everybody should be thanking him for what he has given us. It makes working with ML RAW worth it. GREAT JOB THOMAS! I THANK YOU FOR YOUR WORK. Set up a donation box so I can reward you!
 
I concur with JCS and dusty on ACR debayering looking better than Resolve, I opened a shot of the talent from my narrative shoot in Resolve and it just didn't look quite right. The other problem with ACR aside from it being turtle is the exposure flicker issue. In my narrative scene with minimal camera movement I get exposure shifts if I touch any of the luma sliders, so I have to do all the luma corrections after debayering.

EDIT: just as I though, you can't really tell with the DVX uploads. I have to get out the door but I will update this later and even do more examples and upload the full rez to my dropbox so that you guys can see clearer. But with these uploads, take notice of the specular highlight on the chrome can holding the wooden kitchen tools. See that green fringe along the highlight of the R9 version where the ACR version is clean without the green fringe?

Yes you can tell....at least I can easily. The first thing I saw was the weaves on the basket...noisy and less detail on the R9 vs LM.
 
I like my raw raw, no artificial flavouring. ACR/AE is a *****, but so far it's the only way to preserve the integrity of the digital negative.

Thanks to @dustwaterwindfire, I got my BMC debayering tests processed with Resolve:

It's just as good as ACR, so, for projects without lots of VFX, my preferred workflow would be: shoot raw, use DANewman's utility to convert that directly into CineForm RAW http://www.magiclantern.fm/forum/index.php?topic=5479.50 (no need to convert to DNG first), edit using Premiere, export to Resolve, do color grading and rendering there.

Maybe there's something with the 5D DNGs, either which way I guess it doesn't matter.
 
Yeah maybe. There's plenty of ways to break the raw files in ACR/AE too, I think I've tried them all. :cheesy:
 
ACR shows better than R9 in Samuel's tests too. Look closely at the edges. Try sharpening in R9 to match ACR's default (25). It looks like ACR is sharpening during de-Bayering. Perhaps R10 will do better.
 
speaking of sharpen, in ACR/LR it's better to turn down the sharpen radius to minimun 0.5 (1.0 default), and "amount" between 25 and 75 gives more natural sharpness and less halo (the digital look)
 
Man, I step away for a day and it feels like an ocean has opened up.
Anyone tried Thomas Worth's program yet?

On another note, here's a silly question.
Finally received a Komputerbay 64Gb card to play catch up with you guys.
What are you doing to test the speed of your CF cards?
 
1. Worth's program works.
2. 2 Komputerbay 64GB cards and a 32GB work fine at 1920x1080. 128GB Komputerbay maxed at 1920x900. (my tests)
3. Speed testing: in camera shooting raw.
 
Any shorts or commercials or anything besides test videos that were shot with the RAW hack?

Is it usable for projects yet?
 
[not a scientific test, just some observations you can test yourself]

ACR + AE

Resolve 9
R9.jpg

Note the de-Bayer color edge errors in R9, not present in ACR+AE (or not as severe). Note the extra detail/resolution in the paperclip icons in ACR+AE. ACR+AE image is also cleaner due to noise reduction (NR). I'd prefer to use Resolve vs. ACR+AE (2x faster on my hardware), however not at this quality loss.

de-Bayering is a hard problem. Adobe is using a better algorithm, likely on the CPU. Resolve is probably using a GPU-based algorithm (much faster).
For other developers/image processing folks who are curious:

Not going to even look at the USPTO to see all the patents...

Quick question, if I want to update my camera to the latest hack do I need to re install magic lantern from scratch or just replace the raw video module? Thanks!

Yes, but how do you get the actual write speed of the card (MB/s)?
Need to see where my card tops out at actually, not theoretically.
What kind of material do I need to test/shoot (something highly detailed, running water or the opposite for instance?) and what app is the write speed best read in?

I formatted my card in the camera, saved the files created by the camera in a folder on my desktop named "Magic Lantern". I then put the Autoexec, ML and ****.fir in the folder too. I format my CF card with exfat and then place all of the files on to the newly exfat formatted card... when I change the firmware, like I did today.. I updated both the ML and .fir ... the camera recognised it immediately...

Loved your CCCP piece by the way, some beautiful shots... great work!!

You can use a program called h2testw (google for free download) to find the read and write speeds of your cards...

The information is also provided by the magic lantern software as you scroll through the various resolutions. The higher the res, the faster the cards you'll need!! :)

Depends on lenses. With my vintage glass the default has been just about perfect, very film like with no edge yuckyness.
