Converting live video to animated?

You mean like a "smart button."

Combinations of filters such as find edges and posterize produce some decent effects.

But I do it After Effects.

You might also want to look at Studio Artist.

unfortunately, Adobe stopped making an OS 9 application called Streamline. We did a video for Polaris a few years ago using this program. We took the live action video and ran each frame through Adobe Streamline (it traces photos and makes them into vector art that you can choose number of colors and how much detail). While tedious, it came out fantastic and was NOT expensive. I haven't messed with it yet, but apparently they've tried to incorporate that ability into the current version of Adobe Illustrator.

This software claims to do just what you're asking. Post back if you end up using it.

There is a Filter that is kind of what you're asking in Motion.
It's under the Glow category. It's called Gloom.
