 You do not need 2/n-pass encoding to get a good quality/bitrate.

 Depending on the video you encode, n-pass encoding might not help much
 to reduce the bitrate. Filtering (or something described in the mjpeg
 howto section: Optimizing the stream) might help as much. 

But you need it in order to hit a target bitrate easily. IMHO that's
what (variable bitrate) n-pass encoding is mainly about.
It's not really trivial to find the setting needed for mpeg2enc to
produce a file that fits nicely on a CD/DVD. So it would be a big
step forward to have 2-pass encoding IMHO.

[Mjpeg-users] 2-pass mpeg2

2003-08-14 Thread Greg Trounson
Greetings,
Does anyone here know when mpeg2enc will support 2-pass mpeg2 encoding? 
   MPlayer does 2-pass DivX quite well, but doesn't do mpeg2, so can't 
be used for SVCD creation.

The absence of this capability under Linux seems to be one thing keeping 
a lot of video enthusiasts away.

Greg
