chroma-key
Background substitution technique
Chroma-key is a visual effects technique that replaces a specific color in video footage with another image or background.
The subject is filmed against a uniform colored screen—typically bright green or blue—which is then made transparent in post-production: The weather forecaster stands in front of a chroma-key screen showing the radar map.
Also called green screen or blue screen.
