Re: How to get the moving vector effect

This looks like simply adjusting or re-drawing parts of the illustration so you have two slightly different versions, and rapidly cycling between them. There is an expression/effect in AE that can be used for getting the same or similar effect, called the wiggler, but you would have to control what parts of the image it was applied to. Dunno, not yet an AE guy myself. I'm guessing you could do that with some kind of invisible (to camera) mask layer. The animation itself looks pretty primitive and could have been done with the puppeteering function in AE or stand-alone in a program like toonboom or swish, anything that lets you mark out bones and keyframe them to warp the image.

The last time I tried to get this kind of Doctor Katz Squiggle-Vision(tm) look, all I did was alter two drawings to be slightly different from each other, and set up the DVE to rapidly alternate them at a frame rate of around 8-20 per second. The blink rate is key to get the effect without making it too annoying, and it takes some cut-and-try to do. Frankly, though the documentary looks awesome, I would have liked it more if they'd used a third and maybe fourth frame to alternate between the two jiggling ones, because it started to annoy me a little with the repetitive nature of the effect. This kind of effect should be a spice, not the main course of the meal.

Google up some video of "stick figure theatre" from "Liquid television" for a contrasting application of the look.
