I will. But my objective and the reason I do that is to do as much as possible in float space. And my questions in the user mailing lists are also to see what FFMPEG's discreet YUV to RGB48 conversion looks like (if it looks pristine to me, I will leave the YUV to RGB conversion to FFMPEG and concentrate on the rest).
