Here’s a video I produced for OnlineVideo.net on using Premiere Pro’s Ultra Key and Garbage Matte. It’s an intro- to mid-level video that applies the effect on three videos of varying complexity. The good news? One video is of a (fully clothed) lovely dancing lady. The bad news? The lady’s face is not showing (those pesky permission issues) and the other videos are of me.
All joking aside, if you’ve never used Premiere Pro’s Ultra key and you plan to do so in the near term, the tutorial is worth a look.
