FCPX to Adobe After Effects roundtrip with Apple ProRes 4444XQ - Gamma is off

Update 12-16-14 from Adobe:

Media Encoder CC (2014.1) Bug Fixes

• Fixed: ProRes XQ sources decode with incorrect gamma setting

So I need to test again to see if this problem has been fixed with AE as well.

---------

A file (bars) is exported from FCPX, imported into AE, a Composition is rendered, the rendered file is imported into FCPX. We're using the same codec for FCPX Project settings, Export settings, Render settings.

It seems to be a Gamma issue. The highlights (100 IRE) are fine, the blacks (0 IRE) are fine, but everything in between is compressed = darker.

And it is visible as soon as the file is imported into AE, so it looks like AE misinterprets the ProRes4444XQ codec on import.

DaVinci Lite 11 on the other hand has a perfect roundtrip with no shift.

Hopefully we will get an update from Adobe that fixes this problem. From my tests, every other flavor of ProRes imports /roundtrips fine with AE CC, with no shift.

Note that only ProRes4444 and ProRes4444XQ have no Embedded Color Profiles in AE. All the other flavors of ProRes (422LT, 422, 422HQ) are in Rec709. But ProRes4444XQ is the only one that exhibits a shift

Below are the same before/after with ProRes4444, with no shift.

Are you experimenting the same shift / darker result on your system?
