The quickest solution I have used and would recommend is to download a demo of Poser, pretty much all the versions have it.
There is a feature within the program where you can create sketch animation from the figures you create. However, you can also import quicktime movies to use in the background and it also sketches them too! It’s fast and you have a lot of control over the look of it. Once you export that out of Poser as an image sequence or Quicktime file you can further stylize it in AE to your liking.
I’ve not seen any plug in in AE or Photoshop that comes close to the result.
