Looking for a full-res DNG captured from 6D, with any recent build where this feature works. Subject doesn't matter much, just looking for something decent enough to include in the QEMU test suite.

The full-res DNGs I already have from 6D (including the ones from VRAM dumps) have incorrect size. They are 5568x3708, but emulation expects 5568x3723. Older builds used to have this incorrect size hardcoded.

Here's a full-res silent DNG...not sure if it has the correct size, but it's made with a recent build.

Almost there; one line of pixels missing, since the full image size is an odd number and ML rounds it to an even number. No big deal, I can fill it with something.

Hello everyone, I’m about to buy a 6D and I would like to know what is the res at 24 fps and 30 fps, I can get without the camera stop record after few sec. Thanks guy

Yes, you can do it with reduced resolution. I think 16xx will let you shot continuous in 10 bit.

Since the introduction of lossless raw recording things got better.

Canon 6D highest resolution for 16:9 aspect ratio is 1824 x 1026.

24 fps in 1824 x 1026 resolution:
In 14 bit lossless raw gives about 30 seconds recording time till buffer is full.
In 12 bit lossless raw gives about 100 seconds recording time till buffer is full.

30 fps in 1824 x 1026 resolution:
In 14 bit lossless raw gives about 10 seconds recording time till buffer is full.
In 12 bit lossless raw gives about 20 seconds recording time till buffer is full.

If you really want continuous recording times, you could lower resolution a little.
For 24 fps, 1728 x 972 resolution in 12 bit lossless should give about unlimited recording time (till battery is empty or card is full  :P )
For unlimited recording time in 30 fps you need to lower resolution to 1600 x 900 and record in 12 bit lossless.

Another option instead is go wider then 16:9 aspect ratio.
For example 1:2.39 (which is very common aspect ratio for movies)
1824 x 764 x 24 fps x 14 bit lossless raw recording gives continuous recording time.
1824 x 764 x 30 fps x 12 bit lossless raw recording gives continuous recording time.

That said, if you really like to live on the edge, go buy a Sandisk extreme pro card and make use of the very experimental SD-UHS hack module, which makes it possible to get higher writing speeds, instead of about 40MB/s you can get 60+MB/s writing speed out of your Canon.
This makes it possible to get continuous recording in 1824 x 1026 x 14 bit lossless x 30 fps.

Hello, im new with using raw. i got a Sandisk extreme pro 95mb and got around 7 sec in 24 fps 1824 x 1026 resolution 14 bit. which is pretty standard i guess with 40/41 mb.
Could you expand on how to get 30 sec?
also could you explain how to get in 12 or 10 bit mode?

PD: today i've updated magic lantern on my 6d (Nightly build july 3) and added a sd uhs module for the 6d but it give me a error
Thanks!

I see you're using the nightly build. Not sure if the nightly build has lossless raw and 12 bit option etc.

For the ultimate magic lantern :D experience, I suggest you try the 'crop_rec_4K' build for the 6d on the experiments page.
Go to the Magic lantern main page and under 'Downloads' you will see a submenu, choose 'experiments'.
https://builds.magiclantern.fm/experiments.html

Scroll down to the '4K raw video recording; lossless compression' builds.
The name for the build is a little misleading, since a true 4K option, with at least 24fps, only exist on the 5dIII
Direct link to the 6d build:
https://builds.magiclantern.fm/jenkins/job/crop_rec_4k/80/artifact/platform/6D.116/magiclantern-crop_rec_4k.2018Jul22.6D116.zip
This build has lossless raw options and lower bit depth options.
You can choose raw format within the raw video menu, using the 'q' button on your camera to acces the submenu.

The SD_UHS module doesn't work with all builds of Magic Lantern, but it should work with the crop_rec_4K build from the experiments page.
But I suggest you first try out stuff without the SD_UHS module, get a little feeling with raw video and raw lossless video.
After that you can still see if you really need it. Not sure if you already read the whole SD_UHS thread:
https://www.magiclantern.fm/forum/index.php?topic=12862.0
But it appears there is some little risk in corrupting your SD card, if not correctly used.
I've never encountered any problems with the SD_UHS module, but it is good to know there is some risk involved.

EDIT:
Be sure you enable and use the MLV_Lite module for raw recording, MLV_Rec module has no use in this build and is best not to be enabled.
The MLV_Lite module has the lossless and lower bit depth options for raw video.
