Which Effect??

[Snafu]

What is the effect used in After Effects that is used to make a "paint drip"? on text and other video/where can you get it?

[Alan Mills]

Can't answer your question but a decent enough starting point for After Effects would be to stop by at http://www.creativecow.net/articles/aftereffects.html

There's loads of tutorials and they just might have what you're after.
