Untested, and just to give an idea of how it can be done: mencoder -oac copy -ovc lavc -lavcopts vcodec=mpeg1video:vbitrate=5000 -vf eq2=eq2=1:1:0:0.8 -o output.mpg input.avi All of the same can be done through transcode but the command line will be a bit more complicated. I would use mencoder for this partitcular task... basically using it as ffmpeg plus the eq2 filter. There are of course many more options possible to improve the quality, but that's the basics. It's the eq2 filter from mplayer that does the important magic.
