Green screen may be a new word for beginners for video editing, but it is widely used in movies and videos for filmmakers. Do you know what is green screen and how to use green screen? Since iMovie allows users to apply green screen effect to their videos, we will show you how to use green screen on iMovie step by step. Actually, green screen is not exclusive to professional editors. Everyone can use it to make their video creative.

What is Green Screen or Chroma Key

In movies and on television, actors sometimes fly through elaborate and fantastic landscapes that simply don't exist in the real world. This high-tech fakery happens with the help of a process called "chroma key," also referred to as "green screen" due to the backdrops' color, which is typically a vivid green.

Technically known as chroma-keying, green screening is the process of masking a video using color– removing specific parts so you can overlay one video on top of another. An obvious example is the weather, where a presenter will stand in front of what appears to be a giant map - in fact, they're standing in front of a green screen and the weather map is being added later.
