...for RGB. RGB has resolution, framerate, prehaps even interlace and aspect ratio... But chroma subsampling? no. And this is where much of the complexity comes. If we were to combine them, we would be, essentially, doing it something like this: Value Meaning 0 RGB 1 YUV444 2 YUV422 3 YUV420 4 YUV411 ..... And then spend an additional field on bits/channel, whereas both chroma channels in YUV is are going to have the same size. Oh, please, let there not be an exception to this. Now, keep in mind, that calling two codecs different is a conceptual one. If th...
