birdie Artem S. Tashkinov Join Date: Dec 2006 Posts: 378	Lossless AV1 encoding SVT-AV1 doesn't support it. Rav1e neither. libaom-av1 in my own testing (yuv420p10le source, ffmpeg 6.1.1 params: -c:v libaom-av1 -crf 0 -aom-params lossless=1; libaom-3.8.2) produces lossless output only for I (key) frames. How did I verify? Code: ffmpeg -i input.mp4 -f framemd5 input.txt ffmpeg -i output.mp4 -f framemd5 output.txt Are there any free lossless AV1 encoders?
