Green Screen, also known as Chroma Key, is a basic but powerful technique used in video production and editing. It involves filming people or objects in front of a bright green background, which can then be replaced with any scene or setting during editing. This is the same technology used in weather forecasts where meteorologists appear to be standing in front of weather maps, or in movies where actors appear to be in fantastic locations. It's a fundamental skill in video editing that allows creators to add backgrounds, special effects, or virtual sets without needing to film in actual locations.
