[MPlayer-users] mencoder 2-pass

[Matthias Wieser]

Hi,

what's the preferred method for 2-pass encoding into mpeg4?

Documentation only says:
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

Some people recommend to use constant quantisizer for the first pass, some 
recommend to use the same variable bitrate as in pass two.

What should produce better quality nowadays?

regards,
 Matthias
