If it helps here are 10 and 12 bit ProRes Test Patterns and ramps generated in DaVinci Resolve if it helps somehow to see difference: https://www.dropbox.com/sh/bak63hnr7mnpgbj/AAAf-rMK0LvHYTAFjPuQaaxFa?dl=0 Apply min/max input in Levels and easy see the difference in 10 vs 12 bit gradient like this: https://forum.doom9.org/showthread.php?t=181848 -- Ticket URL: <https://trac.ffmpeg.org/ticket/8054#comment:2> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
