I can't find any docs on how to do VBR with ffmpeg.

Does this look right?

ffmpeg -pass 1 -i SOURCE.MPG -vcodec mpeg4 -b 152 -acodec aac -ab 64 output.mp4

ffmpeg -pass 2 -y -i SOURCE.MPG -vcodec mpeg4 -b 152 -acodec aac -ab 64 output.mp4

Should I use -sameq? How to use?
Should I set a max/min bitrate?

Thank you.

:thanks:
