FFmpeg doing Xvid 2-pass ignores bitrate.
x264 works good as expected, but Xvid only works well for 1-pass.
With Xvid 1-pass the file size changes with the bitrate.
But with Xvid 2-pass, constant file size no matter what the bitrate.
The only file size change comes from varying the audio bitrate.
Xvid 2-pass at 800kbs or 3000kbs, the file size is just under 3GB.
I`d really like to fix this as 2-passes really improves the movie quality.
