In addition to the comments provided by Giacomo, you should also do 2 pass
encoding or you're probably not going to be happy with the results.

This is a common one I use. You may want to adjust the bitrate or other
options:

mencoder infile.mpg -o /dev/null -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=1100:mbd=2:vpass=1:vqmin=2:vqmax=31 -oac copy
mencoder infile.mpg -o outfile.avi -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=1100:mbd=2:vpass=2:vqmin=2:vqmax=31 -oac copy
