You say "RGB to Y'CbCr" routine, and then converted > YUV video. If you take YUV as input, you need a "Y'CbCr to RGB" routine. I have both ways conversions: Y'CbCr <-> RGB, and both according to the newer colorspace FAQ coefficients/terminology are really Y'PbPr. I havn't tested the RGB -> Y'CbCr direction, but the Y'CbCr -> RGB converts bttv YUV data and the colors look normal. Ben
