If you are referring to making your video look like the current commercial vogue of a quasi cartoon look, I know of 2 options. I believe Spot has a tutorial about using Vegas filters to accomplish this on the Sundance site, and New Blue FX has plugins for Vegas and other NLEs to do this.
New Blue FX gave us a free plug in, about 2 or 3 months ago. You'd have to do a search to see if the link is still available.
It works real easy, although slower to render.
If you're planning on making it look like a charles schwabb add, good luck. that requires some serious amounts of work. last I know they actually do that frame by frame after an application converts it for them, and they go through and make sure that things come out smoothly by hand adjusting each individual frame.
you can try with the NBFX one, but it's not going to do it, and to accomplish the look your going to be going for you'll need to slightly blur things a bit too, and the FX will just keep piling on.
However, you can get something close to it, using either NBFX's one or edge detective from VASST.
