A long time ago I came across a website that asked me to submit my name into a form before viewing the video. After submitting my name the video simply played. But the coolest thing was that the video had my name in it all over the place. There was a clip with a bus and my name was on the side, etc. What is that technique called in AE and where can I find tutorials on how to accomplish it?
That's not an aftereffects trick, it's a Java HTML5 or flash trick. It may be possible to write a script that would automate some of that process. It is not built in to After Effects.
