So you know that shot in movies where it's supposed to be a POV of a person waking up, and you see the "eyelids" open and close as like black half-circles on the top and bottom of the screen. Yeah I need a tutorial or something for that for After Effects (If you can't find it for After Effects specifically, any other will do and I'll improvise). I've tried searching for it but I just don't know what to call it. KTHX.
