colour / chroma keying
Chroma key is a special effect achieved by the use of green or blue screen, chroma key green or blue paint. The feature enables users to remove a specific colour from an image or video, allowing the removed portion of the clip to be replaced with a different visual.
Any colour can be removed with your software but typically filmmakers use colours less frequently found in clothing and wardrobes, i.e. bright green.
Adobe Premiere Pro has a feature called "Ultra Key" - this is a smart tool that does a better job at removing your selected area as opposed to just relying on the colour alone. The Ultra Key effect can be used to set any colour in an image to become transparent and offers additional controls to refine the result.
