Doing an RGB encoded intermediate file i dont see any noticeable colorshift. But that normally means uncompressed, and very large files, for FFmpeg to be able to read it. Interesting. One issue I would anticipate is that H.264 is typically 4:2:0, so if you save in another YUV format, FFmpeg would have to convert it, possibly by converting back to RGB. I would hope there was some 4:2:0 YUV format that wouldn't involve those issues, but I don't know. Brendan |
