A very popular effect explained here by Wes James. Take a video, freeze the action and then highlight a section in Final Cut Pro after cutting the guy out in Photoshop.

I've had to do this quite a few times for clients. The hardest part is the cutting out in Photoshop. This tutorial should prove popular to highlight anything from products for corporate videos to skateboarders! Thanks again Wes, a pretty cool tutorial and finished result. Also slightly ironic after my speedramping rant below :)
