How to Use Green Screen in iMovie

In this article, I explain how you can use the green screen effect in iMovie. More specifically, I will explain how you can remove a green (or blue) screen background from your videos and then how you can replace the green background with any background of your choice in iMovie on your iPhone, iPad, iPod touch, or Mac.

The green screen effect (also called chroma key) is when you remove the real background of a video and replace it with a digital background. This is a technique used in a lot of blockbusters movies, television shows. They were filmed in front of a green or blue screen. In fact, everyone from Hollywood producers to YouTubers utilizes the power of a green screen. You can easily replicate this technique.

The process is really simple:

  • Record your video in front of a green or blue screen. You can use your iPhone, iPad, or iPod touch to record your movie. You can also use iMovie to record.
  • Then the background is removed and replaced with whatever background image or video you want digitally in post-production editing, using video editing software such as iMovie.

For example, you can record yourself in front of a green screen, and then you can replace the background with an exotic destination.

Now you are done. You can save your new video.


1. You can make the background longer or shorter so that it matches your green screen video. Simply, drag the end of the clip to make the background longer. In fact, you may want to do this, because now two videos are connected. Thus, the length of your background video clip should match the length of your green-screen clip.

3. Click the green screen video, and then click the Video Overlay Settings icon. This will reveal additional settings:
