Of course - thanks for looking into it.

5D3.113 build of commit 1ed47316133855e7f459c98ec52f4e79e4f27952

Modules enabled:
- bench
- crop_rec
- mlv_lite
- mlv_play
- mlv_sound

Sound enabled in the Audio menu

Canon settings:
1080/24P All-I

ML Movie settings:
FPS override off or exact 23.976 (doesn't seem to matter which)
Image Fine Tuning -> Shutter +0.84ms (1/48)
Crop mode either 3k or UHD 1:1
Resolution 3072 in 2.39 crop
SRM memory enabled (disabling it shortens record time for me)
14bit lossless

Edit: Global Draw in auto mode

Happy to try anything to help - just let me know! Does this work for you? What are you using to convert the MLV files?

Thanks

John

Compiling the latest state of the "crop_rec_4k_mlv_snd" branch gives me this error on all takes using the 3k 1:1 mode.

This is with a Lexar 1066 card, and it seems to run fine for about 8-10 seconds and then bug out with that error dumped to the card. This is mlv_sound module enabled and the module turned on in the audio menu. On the normal crop_rec branch the 3k is continuous without any issues.

I'm still a little stuck on this - Footage and mlv_dump seem pretty convinced there is sound in there for higher resolutions looking at the metadata, but when exported it's just an empty WAV file. I'm still trying to work out if this an in-camera thing or mlv_dump that isn't doing the right thing.

I have to say though, on the 5d3, the FF 1080p 14bit is stunning quality if you de-bayer it onto a 4k timeline in Resolve, rather than upscaling the video at the end of mastering it. Obviously 4k is way slower to work with, so I tend to edit in on a DCI2k 2.39 timeline, and then just flick the timeline resolution up to the 4k option before delivery. Not saying that higher resolutions aren't necessary, but the most exciting thing for me is 14 bit compressed RAW with audio - a ~45% space saving makes a huge difference on bigger projects!

Yes, please.

So compiling the PR for audio (with the 11 commits to crop_rec_4k since it was opened), gives me the following on 5D3.113:

- Modules enable fine and I can enable mlv_sound in the sound menu
- Sound records in MLV videos in full-sensor mode
- Sometimes when hitting stop, there is an error message on screen stating that "sound did not stop: state 5", however I can't reliably recreate it.
- There seems to be significantly more write speed required than "advertised" when sound is on - my slower Sandisk Extreme 120 card can't keep up for more than 400 frames with sound, when it can go continuous compressed raw without. Lexar Pro 1066x card is fine at 3k 2.39 though.

I'm a bit unsure of what the outcome should be when recording sound in the new crop_rec mode. There is a WAV output at the end of the run with mlv_dump, but it is only 44 bytes on crop_rec videos. Still new around here - is mlv_dump another compilation target within the magic lantern repo? I'll get googling.

Will report back as I come across more.

Hi folks - recent convert from GH4 and love it. I noticed your comment below @g3gg0

having patches on my disk.
wont take too long.

I assume that maps to this PR: https://bitbucket.org/hudson/magic-lantern/pull-requests/837/mlv_snd-and-dual_iso-support-for-mlv_lite ? If so, would have some testing done help at all? Happy compiling and checking it out on the 5d3 if that's of use.
