I'm wanting to create an effect similar to the text effect in the opening credits of "Scott Pilgrim" (see 1:34 for the best example). Instead of text, though, I want to use it to "stroke" a person. I have an idea of how I could apply it to an entire scene - using a few saturated & transparent duplicates and using a quick wiggle on each. I really want to apply it to just the person in the scene though. I think I could still use this process and adding some masking. Unfortunately, masking is where I am weakest when it comes to AE.
Does anyone have a more elegant or simple idea?
Is there a plugin that might be able to pull this off more easily?
Sadly, the footage cannot be redone so a chroma mask isn't going to be possible.
How about using Rotobrush?
Short and sweet. Thank you sir!
That's just a graphic overlaid on the image probably with the blend mode set to add, a little blur, some roughen edges and maybe a little distortion. The trick here is layers. From your description you want to outline a person then apply some kind of ratty edge effect with a white stroke. You'll need a layer for the person, some kind of roto or greenscreen work to generate an alpha channel, then some kid of edge effect. Auto-trace would give you an animated path from an alpha channel. Rotobrush would give you the alpha channel. Get the alpha channel and experiment.
