Hi guys, I have been working with a video over a number of months and everything was perfect until yesterday. The videos I am using now suddenly flicker black for no apparent reason - the background is transparent and was working fine until now. I am exporting as WebM so cannot upload the video here. I am using MacOS Monterey and currently AE 22.0.1 (I have been trying different versions as well as the latest and still have the issue). Does anyone have any idea how to resolve this? If I can provide any more info please let me know.
Your screenshot tells us nothing at all about your workflow or what might be causing the problem. WEBM is not a standard production format for RGBA video, and it is a real resource hog for the CPU to decode it. You might want to try another codec.
