In this Photoshop tutorial, Richard Harrington shows how to take a video clip and turn it into a clean still or clean plate for use as a background plate when working on chroma key projects. The technique to make this all work is called averaging video frames and is available through Photoshop CS3 Extended. By using import video to layers in Photoshop, converting the layers to a smart object, then changing the stack mode to mean or median, you get a nice clean plate for your background.
