What is iMovie Green Screen or Chroma Key effect? If you shoot a video with a single colored background (often green or blue), iMovie allows you to make that color transparent. You can replace the background with any other video clip, graphic or still image as you like. That is the green screen effect in iMovie. What is Keying? Keying is the process of isolating a single color or brightness value in an electronic image and using software to make that value transparent, allowing another image to show through the affected areas. So why is that odd and ugly shade of green the hue of choice for television and video? The biggest factor is contrast. In order to isolate one area from the rest, the background color must be distinctly different. Bright green beats blue partially because it is not a color commonly worn by talent. Any clothing that matches the background too closely will also key out, punching a hole in your subject’s body, or making him invisible altogether.
