Currently we can choose to encode prores 4444, however being able to output in prores 4444 XQ would be great.
(This is a future feature request- as I believe that even AVFoundation does not allow this yet)

Correct. We looked for a documented or undocumented way to encode ProRes 4444 XQ and didn’t find anything as of OS 10.11. Related forum posts: ProRes 4444 XQ in AVFoundation | Apple Developer Forums and Redirecting to Google Groups
I’m marking this “tabled” since it’s not currently possible. We can open it up if Apple does add support for creating ProRes 4444 XQ.
