I am reading here on the forum that viddll supports prores4444, but for some reason I can not use it with jit.record - it does not appear on the list of options?

prores4444-and-jit-record-on-windows

it's not one of the officially supported codecs due to its inefficient encoder, but you can make it work if you're doing non-realtime recording.

in the options dictionary (see helpfile), send "set profile 4444"

you can also adjust the "bits_per_mb" value in the dict. the default is 8192

if you're on a Mac, best to use the avf engine for prores4444 encoding.

set codec to "prores_ks"

Recently I moved to Windows and essentially I would like to achieve the same result with jit.record on Windows as I did in the past on Mac (using avf and prores4444). Do you maybe know if on Mac/avf the default "bits_per_mb" value is the same (8192)?

Also do you know if huffyuv is in the same "league" as prores4444?

PS: Is "inefficient encoder" linked to viddll/windows or also avf/mac? For me, using prores444 with avf/mac was always working perfect

no idea about the bits on avf encoder. there is no option to change that with avf.

huffyuv is a lossless codec, and gives excellent performance and results, so i guess yes. it unfortunately requires avi container format. one thing you could do is record in realtime with huffyuv, and then rexport that recorded file in non-realtime using a jit.movie framedump (or ffmpeg from the command line).

the inefficiency of prores is only when using the viddll-ffmpeg encoder.
