Another way i’ve found to be effective (although not in Avid or Boris) is to export an image sequence of what you want to “cartoon” and then use Photoshop to alter the image to what you want. Then batch process the entire image sequence.
I believe there is an exact tutorial somewhere (maybe even here at the Cow) that explains the process. I find Photoshop will give you a ton of options for configuring what you want it to look like.
