Magenta Color Shift when exporting ProRes4444 with AE2020 on Windows
In AE2020 Exporting a clip as ProRes4444 Millions of Colors on Windows results in an Output with a color shift towards Magenta. This can only be resolved by changing the codec to Trillions of colors.
Also when Using ProRes 4444 XQ with the same color settings the color shift gets an additions Gamma shift problem.
On AE 2019 this issue was not there. Also on Mac this issue can not be seen.
We tested it on multiple Windows machines and on all of them the problem appears with AE 2020 v.17.1.4
Please fix this problem

Hi, any updates on this? I'm having trouble sending anything to color grade as they see the difference from original and need to do additional adjustments. If I need to fix anything in already graded material, it is even a bigger no no as this messes up color grade that has already been done. Here is a frame of a gradient with an original quality and then one rendered with ProRes 4444 five times over.
Edit: AE Version: Windows 18.2.1.

One thing I've noticed is that if the color check is being done in After Effects, e.g. re-importing the export and checking the color with the info panel, the color will appear to have shifted because AE is color managing the footage. If you select Interpret Footage>Color Mgmt and select preserve RGB, that will give you a much better result. Caveat, I'm not sure how others on here are checking color fidelity, but that answered mine (and our producers) questions quickly.

Today 22 March 2021 - We came across the same problem after rendering ProRes HQ using AE. It is shocking to see this problem is not solved yet!

Do people still have this problem? Because i do... it still had a color shift, specially in red, i tried almost every export avalaible. If i open exactly the same project on mac without modifications it exports fine...

The least thing I want to be doing is checking color integrity after rendering. Like, this is a thing that the app is meant to do nothing less than flawlessly.

This is terrible. It is still there. I thought we left color shifts behind in 2010 or so... 😠

I haven't recognized this ProRes bug yet but ProRes 4444 has many more bugs and it's totally broken in AE 17.1.4:
- After Effects interprets all ProRes 4444 files as "Millions of Colors" (8bit) although they are "Trillions of colors" (16bit)
- Rendering ProRes 4444 with RGB+Alpha with "Alpha Premultiplied" results in wrong Alpha Channel! "Alpha Straight" is OK and works.
- Rendering with "Millions of Colors (8bit)" Data Rate and file size is higher then with "Trillions of Colors (16bit)"! Should be the opposite!!! Whats wrong here?
Adobe please fix this **** I need to work!
Thank you for reporting these issues. We have reproduced the magenta shift it in-house and will work on a fix. I am not seeing the game shift with XQ however. Could you please give me some more info about your steps to reproduce the incorrect output and what apps/settings you're using to validate the output.
