I'm trying to figure out what the best way is to make that all too popular effect of an animated stroke / trail (you see it a lot on Nickolodean & Comedy Channel etc...) however with a lot of texture. Essentially, animated graffiti strokes. I see how to do something like this with Trapcode 3d in After Effects, but it's too smooth and clean. I'm also looking for a flatter stroke so I can simulate that animated black marker effect. A similar effect is also seen in the new ipod nano ad, but i'm looking more for a flat marker texture effect. Suggestions?
Dunno that particular stuff you mentioned, but a few examples I know here in Germany make good use of Maya's Paint FX or Cinema 4D's Sketch & Toon module. If you were to do it in AE, get Trapcode's Particular. By using a set of rugged custom particles you could still create some graffiti-like textured strokes. You can also use displacement and the Roughen Edges effect to get a variation on Stroke effects.
