FFmpeg best settings to encode Blu-Ray

[MvL]

Hi,

I'll use these settings with FFmpeg to encode a Blu-Ray to smaller format.

ffmpeg -y -i input.mkv -c:v libx264 -preset slow -tune film -profile:v high -level 4.1 -crf 19 -c:a copy -c:s copy output.mkv

Are this acceptable settings? Or are there better settings to get better results? Thank you!

That should be fine for playing in a media player. If you want it to be Blu-Ray compatible you might want to try something like this:

ffmpeg -i input.mkv -c:v libx264 -level 41 -pix_fmt yuv420p -preset medium -crf 19 -g 24 -vf setsar=sar=1/1 -threads 8 -x264opts bluray-compat=1:vbv-bufsize=15000:vbv-maxrate=30000 -c:a ac3 -strict experimental -ar 48000 -ab 256k -y output.mkv
pause

Thank you for answering! I do some testing.

What of preset, tune and CRF setting do you guys mostly use?

It depends on the source and it's a matter of tastes. I usually use preset: medium or slow, tune: film, CRF: 19.
