Hi Timothy,
The best codec for XPression would be the XPression codec, though using Apple Prores 4444 also works very well.
By the way: I think you have mistakenly placed this post in the "Video Servers & Replay Systems" community instead of in the "Graphics" community where usually all the XPression related messages are posted.
