Setting up 2 pass encoding in mencoder

[Wyattthedog]

Can someone point me in the right direction.

I am trying to find out how to change the command line in mencoder to enable 2 pass encoding. Hope this is the forum to place this if not just let me know

I believe you have to use 2 commands, ex:
mencoder -dvd 2 -ovc lavc -lavcopts vcodec=mpeg4:vpass=1 -oac copy -o movie.avi
mencoder -dvd 2 -ovc lavc -lavcopts vcodec=mpeg4:vpass=2 -oac copy -o movie.avi

First creates a logfile, second reads it.
