well, so do i... it just that i frequently use mencoder to reduce the size
of my video collection, so i try to learn option to maximize quality.

it maybe because the video is too sort, so the encoder cannot decide the
bitrate properly. altough you're setting bitrate, actually the bitrate
still vary. if you are really forcing a constant bitrate, at the expense of
quality, add vbv_maxrate

-x264encopts bitrate=8000,vbv_maxrate=8000
