This seems to remove metadata ./ffmpeg -f lavfi -i color=black -pix_fmt yuv422p10le -bitexact -vframes 1 -f framecrc - Stream #0:0: Video: rawvideo (Y3[10][10] / 0xA0A3359), yuv422p10le(tv, progressive), 320x240 [SAR 1:1 DAR 4:3], q=2-31, 38400 kb/s, 25 fps, 25 tbn vs Stream #0:0: Video: rawvideo (Y3[10][10] / 0xA0A3359), yuv422p10le(progressive), 320x240 [SAR 1:1 DAR 4:3], q=2-31, 38400 kb/s, 25 fps, 25 tbn when its stored in a file, it results in a different output, example: ./ffmpeg -f lavfi -i color=black -pix_fmt yuv422p10le -bitexact -vframes 1 -c:v ffv1 -level 3 -y ffv1-lavf-black-4636-new.mkv I have not investigated what is correct, but i would think "no range information" would seem worse than whatever the correct is thx [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Elect your leaders based on what they did after the last election, not based on what they say before an election.
