    I am keying out someone in front of a green screen. Looks great except randomly throughout the video there are these darkened, slightly glitchy frames. (see attached pic)

    The strange thing is that if I change almost any parameter in Keylight (screen gain, screen matte replace method), the glitch will be corrected for that frame, but then it will just do it on another frame later.

    Not sure, but this may have started when I upgraded to Windows 10.

    Any ideas?

    Using After Effects CC2018. Windows 10. Quad Core with 32GB RAM

    Is the footage using an H.264 codec? If so, try transcoding it to ProRes first and then key the new ProRes file.

    It’s MPEG-4 Quicktime .mov footage

    Converted footage to ProRes and still happens.

    I am also very often getting the “Keylight out of memory”. Related?

    Probably related, yes. What are your memory preference settings?
