Chroma Key Compositing

Chroma Key Compositing: Technique of combining and replacing multiple layers of video. Commonly referred to as “green screening,” capturing a video with a green screen background enables an editor or producer to “replace” the background with an image and leave the foreground intact. This allows a video production to customize the backgrounds. This is very difficult to do for oral history as it requires a great deal of computing power and oral history interviews in their raw form are long, large digital video files. This is usually associated with production phases of disseminating video. [Video Glossary]
