However, in the case of 12-bit Prores you will have your input reduced
to 10 bit but that is a limitation of ffmpeg's Prores implementation
(decoder(s) and encoder(s)) rather than yadif. With 12bit prores being
rather rare in the wild and the difference being rather hard to detect
(probably just when doing heavy grading), it seems this hasn't
bothered many people so far.
