12-bit (and 10-bit) RAW video development discussion

[dfort]

Could not reproduce on 700D either. Also noticed that the edmac module should be either updated or removed from the builds posted on the experiments downloads page.



@Dionisgr - Same suggestion, start with a fresh ML configuration. If the issue persists, clearing the Canon settings sometimes helps.

[Dionisgr]

This configuration worked with assemblies: magiclantern-Nightly.2017Mar30.650D104 and  magiclantern-Nightly.2018Jul03.650D104

[dfort]

The configuration changed because raw_twk isn't included in those builds.

Remove the ML/SETTINGS folder, enable modules one at a time and maybe we can figure out what is causing the problem.

Due to the official 7D mk I thread being locked...

I just want to thank @dfort SO MUCH for more updates and work done to the 7D.

I can't wait to download and install the new build for 10-12-14 bit raw recording.

Even with the build from March, this camera is holding up really really strong.

I'm a little bit lost If I want to use mlv lite with sound and compression should I use this one or crop rec from last year? Which one is less bug prone?

edit: ok I tested it and the answer seems to be the crop rec branch? I was just surprised to see that the last update is from last year and this one is more recent.

Unlocked--feel free to post on that topic.

The Digic 4 cameras (7D, 5D2, 50D, 500D, 550D, 60D, 600D, 1100D) are not supported in the crop_rec branches. The raw_video_10bit_12bit_LVState adds support for these older cameras. Note that 10/12bit works but not the lossless compression that is incorporated in the crop_rec_4k branches.

Hi!
First post here, been lurking a few months trying to learn everything I can about ML and I think it's time to show off some 10 bit footage!
A big shoutout to Dfort, thank you for everything you've put into these builds!

Video shot on Canon 7D
Lens was Helios 44-2 + ND
No Grade
Processing was as follows:
7D 10 bit > MLVAPP (LOG-C) > Prores 422 > Adobe Premiere (LOG-C to REC709) > 4k blow up > HEVC

@Spups

Nice!

I love it.
I was looking into that lens! How do you like it?
What build did you use and what RAW settings did you record with?

[Spups]

@domo94

Cheers!

The 44-2 is a very capable lens for video.
Having the stepless aperture ring is nice, and the focus ring is as smooth as butter.
IQ is very good, some of the sharpest old glass in it's price range.
Build quality is outstanding, no rattles or loose parts - you could practically use it as a hammer, lol.

Some things to note:
Stepless aperture is easy to nudge so be aware.
Focus ring has a long travel (270 degrees) so you get a work out pulling focus.
there is an unpainted ring inside the 44-2 that causes flaring wide open, stop down a step and it fixes it.

Overall a very fun lens, with a very fun price tag. I paid £30 for mine and the only time it leaves my 7D is when I need to get close and use my Sigma Superwide II 24mm
I shoot 10 bit @ 23.976p (low jello mode) on DForts may build.

I used 44-2 for a long time on 600d without a problem. Cheap, easy to repair/disassemble if you need.  Great ergonomics. On a full frame it looks differently – corners are never sharp (not good for stitching panoramas, for example), the whole image seems to be much more "artistic". But you need sufficient subject.

10 bit and what resolution? I need to know.
What about all the extra settings such as buffer speed method?
That video looked great!

Encounter any problems?!

Do you need any extra mounts or adapters for this lens to work on the 7d?
Does it work full frame?

[Spups]

@domo94

Resolution was the maximum for 16:9 capture: 1728x972. This can be increased to 1728 x 1152 if you shoot in 3:2 (max resolution the 7D can achieve without x3 crop AFAIK). I may well shoot in 3:2 for a future video, the cost being some black bars on the sides.
I don't touch any buffer settings as I've not encountered any problems with continous recording. I have however changed the liveview settings to use canons view (this stops magic lantern from putting the liveview to black and white when zooming in to confirm focus)

The 44-2 works perfectly on a full frame body, though don't expect razor sharp corners wide open (even my APS-C gets soft around the edge at F2) so you may find F5.6+ works better if global sharpness is a big concern.
you will need an M42 to canon EF adapter. these can be bought very inexpensively, mine was made by Neewer.

Just curious why you didn't MLVAPP (Rec.709) > Prores 422 instead?

Most people who export with a LOG profile from MLVApp like to grade in another program. LOG offers much more room than Rec.709, which mostly cuts shadows and highlights, when not correcting before the export in MLVApp.

Gotcha, thanks.

Hi everybody , I'm new here, I just installed ML on my 5DMK3 and I have issues when I'm shooting in 1920x818 at 25fps 10bits ratio 2.35.1
the image is perfect but I have no sound or just a few seconds... generally the sound is being recorded around 24 seconds after the beginning of the recording and stops few seconds later (but the video recording still runs...)
Does any of you have the same problem ?
Sorry for my bad English , I'm French...

Hello! I am using this branch for a quite while now on my 600D. Unfortunately it has the SD card speed bottleneck. I would like to record raw in a better resolution but only at 8 bits. This way an "almost" 720p resolution would be possible without the compression artifacts.(I know it can be pointless as h264 has the same color depth, but the artifacts and color banding can be minimized.) Would it be possible, to implement an 8 bit raw mode? Thank you!

Hello,

I use on my 7d with the magiclantern-raw_video_10bit_12bit_LVState.2019May15.7D203 (Dfort)
It works quite well even at high resolutions (10bit) but the big drawback is that the framing during recording (preview option) in ML Grayscale mode remains frozen.
In "Canon" mode the framing is smooth but much too zoomed in to be really usable.
Do you know of a version for the 7d that does not have this defect?
If so can you give me the link?

Thank you anticipating your answer.

I've tested this just now on my 7d, we share the same build and the problem persists on mine. I think it's due to this build but I'll take the working 10bit over dodgy 2k!
I reckon best way would be take a few test shots to get your reference before the take. or use greyscale for reference then back to canon for recording- Don't know about you but I only use 2k on static landscapes or cityscapes due to exaggerated CMOS slush lol, so it wouldn't slow the workflow much?
