I see. That kind of "lossless". Huffyuv also says "For RGB input you also have the option of converting to YUY2...This is not lossless, but often it doesn't matter because the same conversion is done anyway when you compress to MPEG..." and I can see the point, more or less. I typically do Src->(some filtering)->Huffyuv RGB->(retouching (involves a lot of copy-and-pasting to/from Clipboard bitmap that is RGB)/more filtering)->Another Huffyuv RGB->Compress, so I personally need RGB to RGB lossless.

Anyway, my random thought was, that snow+RGB was not surprising _because_ snow can be lossless, and I guess this "because" was inappropriate, tho the conclusion itself seems to be right... It's not like I wanted to compress something with snow using RGB. It was just a random thought.
