	The more I think about it the more I think that what I'm looking for is a way 
to specify an average per-frame quantizer. What I'm thinking of is something 
along the lines of: the encoder uses vqmin, vqmax, and vqave (or something 
like that) to select the best quantizer per frame. The encoder would be 
limited not by bitrate but by maintaining an average quantizer. Any chance 
that this ability is anywhere on the horizon for the lavc mpeg4 codec? 
	The best example I have of a blocky solid color encoding is the beginning of 
American Pie 2 in Jim's bedroom. All the walls in his apartment are solid 
green and look very blocky when encoded. I will upload an encoded version as 
soon as I get a chance.
