Re: Animated grunge textures

you can do a lot with fractal noise, just keep playing with the settings...

basic dirt-on-film look can be achieved with by increasing the contrast and brightness to get the amount of dirt wanted, then adjusting scale of the noise. if you animate the evolutions rapidly, you can get a different dirt pattern on every frame.

you can get scratchy textures by drastically changing the noise scale... width: 10, height: 10000 will start to create a vertical streak look. adjusting the brightness and contrast will make them more like scratches. animating the offset value can make it more like scratches on film, animating the evolutions can get you cool results too.

if you want curved scratches, adding turbulent displace can help with that. with a few layers and offsetting the turbulent displace evolutions you can get good organic scratches.

cool light-leak effects can be created with fractal noise with the complexity set really low and the scale set fairly high, then animate the offset and/or evolutions. then add colorama set to the fire output preset (or similar).

also, for any keyed element, you can use roughen edges to grunge up, and of course it can be animated.

the old cc film burn can add dark smudgy spots, adding it to a white solid can allow you to key the film burn effect (just add invert, then unmult, and then invert again) and then you can add roughen edges to create some cool splotches.
