I'm new to RAW video, footage on my Canon 6D looks blocky/compressed

[LICK_THE_BUTTER]

I don't know how this is happening. I am running the latest build and have tried re-installations. Attached is an image of one of the converted MLV files to DNG that I saved out as a JPEG. I am looking mainly at the lines of the metal fence and the grass blades, they look jagged. Lens is a bit soft (Helios 44-2)







For the MLV to DNG conversion i am using the MLV Converter that got popular on here in conjunction with IrfanView. I cannot find the i_view.exe location for some reason, it is invisible to the conversion app. Seems to work without it (i just cancel out of the prompt), it's only for viewing them right?



Anyways on another note, i tried downloading an older version of ML that allows shooting for 10 and 12 bit meaning i can shoot at a higher resolution with 16:9. On my 6D the video playback looks normal, but after using the converter the very top of each DNG picture is ok but the rest below is an absolute noisy mess. You can't distinguish anything, just a bunch of colored noise. It never did this to me with the latest ML build I was running. I'd ideally like to run this build since it gives me the 10 and 12 bit options (cannot understand why this was never kept), below is a link to where i learned about it.

My shooting is for video tutorials at 16:9 in the highest quality obtainable and cinematics in 2.35:1 at the highest quality obtainable (all at 24fps). I have fast cards, no worries there. Just need to find the right build and conversion workflow. I keep on running into road bumps with RAW, and again I'm new to this so feel free to explain like I'm 5.

UPDATE: Tried it again in same location (with latest ML build), am noticing that for one, the video is a little stuttery which might be framerate related. I've tried tuning it as close as i can to 24fps. And two, the holes in the fence have some weird dark pixel artifacting to them, it is very strange and hard to describe. I've noticed this a couple of times before. One of the tutorials ive used for settings up RAW video in ML is this one:

I think the fence doesn't look that bad, they are actually straight lines, so a little jagged lines is expected here.
But the grass does look weird indeed, I don't know what your exact workflow with MLV converter and irfan view is, but looking at the grass it looks to me that there is used a line noise filter or something went wrong with sharpening ?
I can have a look at it if you have a DNG file of your fence example and upload it ?

But overall I'm quite amazed that your picture doesn't have weird colored speckle artifacts, but that's probably due the soft lens, Helios.
The 6d records video with line skipping, reads a sensor line, skips two lines and reads one line again, etc, etc.
This results in jagged lines in subjects with really straight lines, like fences, buildings etc. (and with sharp lenses, also can result in colored artefacts, which can be removed most of the times with software)
If you don't want this, you can record video in 5x zoom mode, press the magnifying button until you are in 5x zoom mode, this way you are recording without line skipping(but you are also using a smaller part of the sensor, not the whole.)

I'm not sure which latest build you are using, but would advise to use the Crop_rec_4K build on the experiments page.
https://builds.magiclantern.fm/experiments.html
Direct link to 6d build:
https://builds.magiclantern.fm/jenkins/job/crop_rec_4k/72/artifact/platform/6D.116/magiclantern-crop_rec_4k.2018Mar10.6D116.zip
The name says 4k, but it doesn't record in 4K, that's for now only the 5d3.

But this build does have lossless recording options.
With this build you must use MLV_Lite and not MLV_rec module.

I would enable the following modules with this build:
MLV_Lite (For recording raw video)
MLV_Play (For playback record mlv files
MLV_snd (For sound recording)
File_man (for browsing MLV files and view them on your camera)

With this build you should be able to record continuous in:
1792 x 1008 (16:9) resolution, 24 FPS in combination with 14 bit lossless option, this should take about 35 Mb/s write speed.
1824 x 776 (2.35:1) resolution, 24FPS in combination with 14 bit lossless option, this should take about 28 Mb/s write speed.

Not sure how long the tutorials are, you want to record, but the 1792 x 1008 with 35Mb/s writing speed is a little at the edge, you have to try for yourself if it also works for long times like 10 or 20 minutes). If not, just lower the resolution a little like for example to 1728 x 972.

Thank you so much for the reply! I have tried the ML build you have shared and I am getting noisy images again. Below is a download to the MLV i did a quick recording of.

http://www.mediafire.com/file/cv9a0y4qcq2zdt6/M26-0904.MLV

I have tried a DNG conversion in ML Raw Viewer but it crashes trying to open it (it's never done that to me before). MLV Converter renders out noisy images with the bottom half black, Photoshop can't even open them. I am also including a screenshot of the converted DNG files. My 6D firmware is 1.1.6 which i downgraded to because it was needed for the latest 6D ML build i started with https://builds.magiclantern.fm/6D-116.html
Could my firmware be the issue? Some builds won't say what firmware update you need to install ML builds which is a little annoying.

Is it still a big price difference between 6D and 5D3? 6D is a great still camera but in video especially with ML the 5D3 quality is much better in terms of sharpness moire, and that you get 1920x1080.

@LICK_THE_BUTTER
Downloaded your MLV and there is nothing wrong with it.
I can see the Rice Krispies
It's the lossless compression, be sure you have the newest converter software, so it can handle the lossless recorded MLV files.

I'm using MLV_dump, which is used in terminal/console, you can download the newest versions also on the experiment page, right above the crop_rec_4K_builds of the cameras.
But there are lots of converters out there which support lossless, maybe check this topic:

Hooooly shit. I love you and this app I just stumbled upon: https://www.magiclantern.fm/forum/index.php?topic=20025.0

I downloaded the latest version and it is exactly what I'm looking for! Super easy and convenient to use! Any reason to hate it? Is it too good to be true? I've only done a simple test and not multiple, but so far so good!

Ok that's extreme. In one way I'am quite surprised of its value. Bought my 5D3 second hand from a landscape photographer for 1700euro here in Sweden, but that's 4 years ago yes a bit lucky but it was so much focus on Nikon and that photographer went to a 1DX, but yes very lucky. Shure it had hit 60000 in shutter count but I've had zero problems with it.

Sorry off topic...

Yes if the price wasn't that huge the solution could be that. I had the 5D2 when ML RAW was new, but didn't like the quality of the image, and save 75mb/s on a memory card when you are not happy with the image didn't feel to good.

@LICK_THE_BUTTER
Good to hear you found out a workflow for the lossless MLV's
