I have updated the version of ffmpeg that I have from 2023-11-15-git-78f55457c9-full_build-www.gyan.dev to ffmpeg version N-120957-g66e40840d1-20250903 and now the same files encoded with the same parameters are larger. The conversion speed of my test file has increased significantly, dropping from 7:38 minutes to 1:20 in the latest version for the same parameters, but the final file size has increased. I have tried with several files and the same thing happens in all of them.
This is the line I use for the conversion, the parameters are set for a minimum VMAF of 96. ffmpeg.exe -i "origen.mp4" -c:a copy -c:v libsvtav1 -crf 32 -preset 6 -svtav1-params tune=1:fast-decode=1 -pix_fmt yuv420p10le -g 240 "destino.mp4" I have a small test file encoded with H.264, 35.7 MB in size. When re-encoded with the old version, it's 25.2 MB, and with the new version, it's 28.9 MB. It may not seem like much, but with larger files, the difference is noticeable. What could be happening? Have the parameters changed? _______________________________________________ ffmpeg-user mailing list -- [email protected] To unsubscribe send an email to [email protected]
