[FFmpeg-user] Using FFMPEG to transcode Blu-ray compliant video

I know this is a relatively old post, but I have a cmd line that Encore CS6
accepts as compliant:

> ffmpeg -i "input.mov" -c:v libx264 -b:v 38M -maxrate 40M -bufsize 30M
> -pix_fmt yuv420p -preset veryslow -tune film -level 4.1 -x264opts
> keyint=30:bluray-compat=1:force-cfr=1:open-gop=1:slices=4:fake-interlaced=1:colorprim=bt709:transfer=bt709:colormatrix=bt709:sar=1/1
> -f H264 -r "$THIS_TIMEBASE" -y "VideoOut.264" -c:a ac3 -b:a "320k" -ar
> 48000 -y "AudioOut.ac3"

This assumes the input is 1920x1080 at 29.97fps. x264bluray.com has you
change the keyint option to match the rounded fps, so that's what I do as
well. Encore only seems to accept standard framesizes (1280x720, 1920x1080),
so make sure your input is one of those or scale to be one of those.
