Here's a sample command. I want to be sure you understand that "-vf
framestep=2,filmdint=fast=0,softskip,harddup" did work better than my
decimate. Anyway, I'm trying to drop any frame that is even remotely similar
to its neighbor with these decimate parameters, and I still don't seem to be
getting that result. Picture quality is excellent, though.

mencoder -oac copy -ovc lavc -lavcopts
