'''Keying''' is the process of taking a certain aspect of a video and "keying it out" (removing) it from the footage. Usually this is done to create transparent segments of the video of which other layers can be placed underneath. | |||
The most common usage of this is the "green screen", where the color green (or blue) will be made transparent. This is commonly done in movies by having a green room the actors will work in; then the background is edited in. Just like in movies, this idea is applied to [[Tennis]] to either remove aspects of a video, or (when working with editors that cannot support alpha channels) key out backgrounds for [[puzzle pieces]] to be used properly. | |||
