How does it work?
In and of itself, a green screen doesn’t actually do very much. They are typically large cloth backdrops or walls that have been painted green, like the green screen wall in our studio. They don’t have any special functionality that makes the effect work.
The “green screen” effect relies on a technique called Chroma Keying. This can be used with any colour, which is why blue screens were used in the past, but luminous green is not a colour that’s typically found in clothing or people’s skin.
When applied, the Chroma Key will remove any green within the video, allowing our editors to place another image or video of your choice in the background.
