If and when my gamma or saturation shifts I do a compensation pass on the front end. I need all the color gamut I can possibly get with ABSOLUTELY no artifacts. We encode for Blu-ray, any artifacting will make itself known on a 60' screen after we compress the HD down to 18Mbs. If there is even so much as a hint of color banding or posterization I will amplify it by a factor of two or more depending on the motion and colors used in the shot. I do not believe Animation is a truly and completely lossless codec. The Animation codec absolutely is a truly and completely lossless codec when set to Best temporal and spatial quality. If you find that not to be the case, it's a bug. You can do a simple test by compressing some footage with it, opening up the compressed footage and placing it over the original footage and setting the blend mode to Difference. If there are any pixels which are not 0, then it's not lossless. (And if that's the case and you're sure you've set it to Best quality, then it's a bug.) FYI: unless you have cartoons and text animation... (flat graphics), normally codecization of file lossless formats like PNG produce much smaller file size _______________________________________________ Do not post admin requests to the list.
