You can easily reproduce the color space conversion problem by taking any rgb24 png image sequence, and then encode it with mencoder. Compare the resulting image with the original and you'll see colors change far more than they should. It is very apparent if you use a video source with large flat color areas, or just a matte color. (I can provide samples if anyone wants them)
That's probably a good idea.
I converted the same rgb24 pngs to yuy2 and back again to a bitmap using premiere to use as a reference - perceptually the colors were the same.
Although, I know relatively little about color space conversion, could the matrices discussed on this avisynth page have something to do with the color shifting?
I don't know (in case you were hoping for an answer from me). -Corey
