[MEncoder-users] two pass encoding with pullup

[Winterbird]

I feel I have to go back to the reason I posted this, because I didn't
really get a clear answer. Is there anything in my options that could
make mencoder fail to put the bits in the right place (causing ugly
moving objects)? Or is it a bug? Or could it be that pullup drops
different frames every pass and that way can't follow the log from the
first pass?

Encoding in three passes makes the encode only slightly better, I havn't
tried more passes, and since encoding with all options activated goes
very slow (0-1 fps) I probably wont have time to in quite some time.

sorry to bother you again...
