PhotoJPEG is good and fast in FCP, and has good size compression, but I can see artifacts
Jpeg2k has good size compression, no noticeable artifacts, but is SLOW in FCP
Uncompressed is damn huge, obviously no lossyness, and is also slow, possibly due to it's general freaky hugeness
Animation - Used only when I need to bring over alpha
Any other options? Is there a codec out there I can buy that beats these? Somebody from Apple want to please please pretty please release a ProRes encoder for Windows?
