[BUG] ProRes DNxHR RGB 444 12 bit Export fail
- Export ProRes DNxHR RGB 444 12 bit with no Alpha, but "premuliplied" setting
- Import the Rendering back into AE.
- Playback reports error. Video is black.
Workaround: Set the output alpha to "straight" even though there is no alpha channel.
Jon Terada commented
I still get a black screen in AE and the ability to interpret footage [alpha channel straight] is greyed out in After Effects 17.7.0
This is fixed in the After Effects 17.5.1 release. We apologize for the inconvenience.
