Thanks, Booli! Sorry about the ex-girlfriend thing
To get the visual effect, I use the "enhancement" feature of YouTube. When you post a video, click on the enhancements button (it looks like a magic wand). After that, look for "filters" and click on that. Then look for the one that says "cartoon." After that, you may have to experiment with the "quick fixes" such as contrast and "fill light" to get the desired effect.
