I've used mencoder many times, but there is something going on that I
just don't understand.
For maybe 80% of the video, everything is fine. Yet every once in a
while, with no pattern that I can discern, everything gets pixelated
as if the bit-rate changed to 700bps. After anywhere from one second
to 3 minutes, the image quality will snap back to beautiful and stay
that way until the next pixelated section.
Oh, and 2-pass is consistently worse image quality than single pass
for me too.
Very strange. This is the command line, if anyone wants to comment.
