Is there a list of the (mathematically) lossless QT codecs that ship with the pro apps (FCP, Motion, QuickTime Pro, etc) ? I'm not sure if there's a list.

There's also "None" and a quite a few with "Uncompressed" in their name as well (if you regard 4:2:2 as not lossy). Gets complicated by your initial colourspace: Animation and None are 8-bit RGB, so any other kind of image in will still experience some loss. I think "Component Video" is uncompressed 4:2:2 YUV, if it's still around. Some of the old QuickTime "Ice floe" newsletters would cover the older codecs in some detail ... There may be others. Most people use Animation for an actual lossless codec. I'm not sure what you're specifically testing, but I've found that lossy codecs today are much less lossy than they used to be. It may or may not make a difference for you. Some testing still requires actual lossless encoding. This email sent to piers@u-h-p.com This email sent to site_archiver@lists.apple.com
