I am having a serious issue with After Effects while working with YUV 10 Bit files. Specifically Prores 422.
The problem occurs not when the footage is brought into AE, but rather when it is exported after an effect has been applied. I am specifically trying to work with the Timewarp plugin. When the clip is brought in, and the effect is applied and then exported, it becomes quite obvious that the highlights in the clip have peaked, creating an clip with light gray, washed out highlights.
As a test I brought the footage into AE, applied no effect, and then exposed it. The highlights were fine. This problem is occurring from the Timewarp plugin.
What version of AE are you using?
AE CC 2015
Sorry, what exact version number? Is it 13.5.0.x or 13.7.2.x or something in between? Also, what OS?
