    I’m experiencing something very odd. I’m using a number of ProRes 4444 files with alpha channels in a project, and for no clear reason I can determine I keep getting these single frame flashes of red ( a pure full frame of red). There are no such frames in the individual files when viewed in Quicktime. My gut feeling is that it has something to do with the alphas, switching between 8, 16 and 32 Bit can yeild differing results but nothing consistent.

    Has anyone had this problem before ? It’s driving me nuts and the deadline is approaching fast…

    Do a fast test- convert the footage to a lossless codec (sequence of files even) and see if you get the same issue.

    have the same problem here since i upgraed to 12.1.

    MAC PRO 2011 with 10.8.5 rendering MP all 12 cores (24 hyperthreaded), 64 GB RAM, 2GB to each core.

    the “red flash frames” appear in my renders when using prores 422HQ clips as footage items in my comps – but also when rendering without prores clips in comps when i apply lens blur as effect (???why???)

    in other situations, the flas frames do not seem to appear

    when i use png sequences as footage items, the problem seems NOT TO HAPPEN

    the “red flashframes” appear in random locations – even if i render the same clip 5 times, the red flash frames appear at different, completely random positions.

    it also happens after a fresh reboot and no other apps running.

    –> seems really random
    i suspect a specific 12.1 bug and hope for a soon update
    12.0 always worked like a charm – this bug appeared only since last week when i upgraded

    Having same issue out of nowhere too. I turned off multi-processing and it rendered clean in my few instances. Considerably slower, but clean.

    We’ve isolated this and have a fix under development. If all goes well, we’ll be able to release an update with a fix very soon.

    The After Effects CC (12.2) update fixes this problem.

    Let us know how it works for you after you’ve installed the update.

    It’s five months after update 12.2 “fixed” the red frame problem and I’m still having it. Did it go away for everyone else?

    There is a different problem with similar symptoms that has an extensive thread about it on the Adobe forums. The fix for it is in the update coming in June.
