Animated grunge textures
on May 2, 2012 at 1:26:13 pm

Allo everybody. I'm working on abstractifying some video. In photoshop, I've done some cool things in the past where I've taken grunge textures (a quick google image search will let you know what I'm talking about) and applied them to other images using various blend modes to dirty up otherwise clean images.

Now I want to try that in After Effects, but I think a still grunge texture overlaid onto a video will look kind of boring. I want to have these textures animated, which I'm assuming means generating them myself from scratch.

So I was wondering of some nifty procedural ways to generate a grunge texture. What I've tried doing is taking animated fractal noise, colorized it with colorama, then adding grain, applying it to my image with hard light blend mode. The result is more murky than grungy. Anyone else have any ideas?
