AE Beta on M1 misreads ProRes 444 colors and renders as black and white

[DouglasRC]

Ran into a bug where a ProRes 444 file's single color comes out as black and white. Specifically, an orange color comes out to black and white while grey text in the video remains grey. Some glitchy artifacting also appears when viewing at a lower preview resolution that isn't seen when I view the same file within AE on my intel iMac.

I'll also add the same file, when transcoded to a ProRes 422 file, the color remains intact and behaves as normal so this seems to be an issue around this version of AE reading a 444 file.

Hi @DouglasRC,

Thanks very much for reporting this issue. I think this might be one of the previously known issues listed on the After Beta M1 announcement. There has since been a fix made for the issue. Would you mind giving this a try in the latest 22.1.1.40 build of After Effects (Beta)?

Thanks very much for any further info,

Hi John,

I just gave this a try and it worked! Updated to the latest AE Beta and the correct orange color is appearing on the ProRes 444 file now, both in the preview and in the final exported version via Media Encoder.
