Not sure what happened between builds, can't use ProRes 444

I updated the beta just now and when I reopened my previous project all the ProRes 444 footage in the project was now causing AE to freak out, tearing and artifacting on the screen. Completely unusable.


System info
    Application: After Effects (Beta) v23.0.0.11
    OS: macOS v12.5.0, RAM: 64.00 GB GB, CPUs (logical): 10

Hi @jackthegiantkiller,

 

I'm sorry you're encountering these tough issues. Thank you for taking the time to write them up. The color shifting on M1 Macs maybe a bug we are working on fixing. You can try try turning OFF Hardware Decode. Preferences > Import > UNCHECK Enable hardware accelerated decoding (requires restart). After restart also clear the disk cache in case After Effects has miscolored frames in the cache. Edit > Purge > All Memory & Disk Cache... . Please let us know if this resolves the issue.

 

Thanks,

Jason

So there appears to a huge bug when using the Lumetri Color plugin on 444 ProRes footage in stable version. I get random flickering where the overall cast of the image goes from cool to warm and back. The flicker pattern can change between renders. I don't get the same results rendering out of Premiere using the same settings, I also didn't get the bug when rendering from the previous Beta. In the current stable version I get the flicker when trying to render 444 footage that has Lumetri, but no flicker when the footage is 422. In the current beta I can't even view the video, its completely garbled.

Today's beta build made no difference, ProRes 444 footage is still coming in scrambled on my M1 Macbook Pro 16 fully maxed out. I finally had to take all my footage, transcode to 422 in Media Encoder and then I could color correct with Lumetri and not have the intermittent flicker in the "stable" version of AE. I also could get stable color correction out of Premiere, but not After Effects. I've included 3 stills (cropped as the project is confidential) that show the color flux that occurs when using Lumetri on 444 ProRes in After Effects 22.5. Sometimes it's an intermittent hue shift, other times it flickers like a strobe. Either way I really hope you guys can get this bug squashed, as I lost almost an entire day trying to get what should have been a simple one-shot render out of AE into a daylong nightmare of moving projects around and trying different combinations of codecs.

    I can't tell you how much time I have wasted today trying to get these projects back and forth between beta, standard and Premiere just to get this rendering consistently. I have never seen so many bugs in a color correction filter than I do with the Lumetri plugins, constant flickering and flashing depending on the direction of the breeze. I am absolutely so frustrated right now I want to throw this laptop across the room.
