I don't know if it is better but, for me, if it works as expected, it will be the answer.
RAW files are huge to keep, sloooow to proceed and I never really liked movie files in image separated manner.
The new codec is far better than the "standard" 4444 ProRes with bigger files so more quality and latitude to grade.
And it will surely react a lot better in all Adobe products like After Effects than DNG ones.

What you expect? Wedding images? trees? What do you expect? Flawles work?
You need to use facts, and sources, for explain it, no lot of adjetives.
14 bits it's not 16 or 12. Where is all that information? Why do you need and alpha channel?
Are you sure Adobe manage the same bits of Apple Pro Res as Final Cut X or DaVinci Resolve?
I mean, sometimes the size of a file it's not the quality. A Pro Res created by a Tiiff 20 bits it's very different from jpg.
I'm not the person with the numbers. The idea is not work with Uncompresses files. That's it's quality.
So, the question is: it's useful work with Apple Pro Ress 4444xQ? Or it's no necessary for our resolution?
