How to Use Green Screen Effect in iMovie on Mac

First off, let’s understand how the green screen effect works!

What is Green Screen Effect in iMovie and How Does It Works? 

To be more precise, the green screen or the blue screen effect allows you to superimpose your video on any background to create an eye-grabbing composite image. Didn’t get it? Well, let me explain it in layman’s terms! For instance, you can shoot someone walking in front of a green backdrop, and then cut out the subject and place it over a clip howing a river. This effect will make that person appear to be walking on water. This is just the tip of the iceberg as you can use it to create a variety of out-of-the-box scenes.  Do note that if the subject is green, always record the video in front of a blue background. Similarly, if the subject of your clip sports a blue color, make sure to shoot against the green background. 

 Create Green Screen Effect in iMovie on Mac

  1. To get going, open iMovie on your Mac.
  2. Then, drag the video that you shot against a green or blue backdrop and place it above a clip in your project. 
  3. Now, click on the Video Overlay Settings icon. 
  4. After that, hit the pop-up menu on the menu and select Green/Blue Screen.  Voila! iMovie app will instantly erase the background of the clip shot against the blue or green background and allow the video below to show through areas that were green/blue. As stated above, it will create a nice-looking composite image. 
  5. Finally, hit the tiny tick or apply button located at the top-right corner of the screen to finish. 

Customize the Green/Blue Screen Effect in iMovie on Mac

  1. Assuming you have already placed the video shot against the green/blue background above a clip in your project. 
  2. Then, click on the Video Overlay Settings icon to reveal multiple options. Besides, make sure that the Green/Blue Screen is selected in the menu. 
  3. Next, you have three options: 

Adjust the softness of the edges: Just drag the Softness slider to fine-tune the softness of the edges of the superimposed video.  Isolate the areas of the green/blue screen clip: Click the Crop icon and then drag the corners of the frame.  Clean up the areas of the green/blue screen effect: Hit the Clean-up button and then precisely drag across stray parts.

  1. Once you have perfectly adjusted the effect, click on the Apply button (the tick mark) to finish.
