Cant cut 10bit 4:2:2 about mpv-cut HOT 6 OPEN

mkv is just a different container, the cut will still be lossless. So it sounds like you should just add the code I sent you to your config.

You're welcome! Have a nice day :)

Can you send a tiny sample video

Thanks for your fast answer, Here is a small video in the same codec. Greets

So this is an issue with ffmpeg, I don't know why it fails to copy the stream to the mov container, but mkv works. So if you don't mind outputting mkv, then it'll work file. You'd just add this to your config.lua file:

ACTIONS.COPY = function(d)
	local args = {
		"ffmpeg",
		"-nostdin", "-y",
		"-loglevel", "error",
		"-ss", d.start_time,
		"-t", d.duration,
		"-i", d.inpath,
		"-c", "copy",
		"-map", "0",
		"-dn",
		"-avoid_negative_ts", "make_zero",
		utils.join_path(d.indir, "COPY_" .. d.channel .. "_" .. d.infile_noext .. "_FROM_" .. d.start_time_hms .. "_TO_" .. d.end_time_hms .. '.mkv')
	}
	mp.command_native_async({
		name = "subprocess",
		args = args,
		playback_only = false,
	}, function() print("Done") end)
end

If you don't want mkv output, you'll have to research why ffmpeg is failing with your footage. You could research some combination of ffmpeg blank output copy stream g5 10 bit hdr 4:2:2 and try to find an ffmpeg command that will work. Then if you do find a solution, you'd modify this copy action with the revised command.

For example if you do ffmpeg -i video.MOV -c copy out.MOV, the result is still black.

It could also be something like our ffmpeg version. But I'll let you test all that :P

Thank you very much for your help ! I don't know the mkv but if it doesnt change the quality of the video it could be great ! :D I'm gonna check as well if i can solve this thru ffmpeg. I will post here if i find something. Have a great day !
