I'm using After Effects CS6, and I'm deliberately trying to recreate the look of a cheap camcorder. I want that stereotypical red "REC" text and big red dot in a corner of the screen, and I want it to blink off and on. I want the "ons" and "offs" spaced one second apart, like so:
ON ==[one second]=> OFF ==[one second]=> ON ==[one second]=> OFF
And so forth. However, animating this by hand is a huge pain. How can I automate this animation? Would an expression work, or is there a way to tell After Effects to loop certain keyframes?
