What is Chroma Keying?


Chroma keying is a visual-effects technique where the background of a scene is removed from the subject of a video. This allows for more freedom in the location you are filming or broadcast from. Part of the foreground footage is made transparent. This allows you to add stills or separately filmed footage to the background of the video or broadcast.


This visual-effects technique is widely used in video production but is also common in the gaming industry and during live television newscasts.
