While I am certainly no expert for avisynth, I don't think this 
makes any sense, using uspp on the original source and a 
(lossless if you want, but I would recommend low constant quantizer) 
yuv420p codec with ffmpeg should save a lot of disk space.

There is no lossy conversion if you do
yv12 -> uspp -> yv12 encoder
(except for the filter itself)

huffyuv in FFmpeg does support RGB, please don't forget that MEncoder 
is not an actively maintained application (FFmpeg is).
