a blue (or green) background in front of which moving subjects are filmed and which allows a separately filmed background to be added to the final image.

How does it work
Through the magic of video effects and technology, you can superimpose your subjects onto virtual backgrounds, place them over animated digital backdrops or transport them to a desert oasis. You can shrink down a full-grown man so he can stand on a tabletop, use visual effects to make him fly through the sky like a superhero or simply simulate your own TV weather report. But to do it right, you’re going to need a lot of green. No, we’re not talking about money. The green we mean comes in the form of a green screen. The secret to pulling your subject out of the real world and placing him or her into a digital domain is chromakey, and that means going green. In this article we’ll cover all the essentials you need to know to pull off keen, clean keys and composite digital backdrops and virtual backgrounds into your edits.

my idea of what i wanna do?
Be invisible As seen in Harry Potter, pupils can make their body invisible by wrapping up in a green screen in front of a green backdrop, before importing in MoviePlus to overlay on another scene using ChromaKey.
Clone For clever scenes where pupils have a twin, capture two videos against a green screen into MoviePlus. Add a 2nd video track to layer them, removing the backgrounds. Try using Transform to flip one clip for a ‘mirrored’ video.
Freeze! Often used in battle scenes, pupils can create slow-mo effects in impossible sets. Record action shots with a green screen, import into MoviePlus to swap backdrops, split clips, slow playback speed or add static frames.
whats good about these is i don't need any props
except if i use the clone i could bring a change of clothes.
