How to Use Green Screen in iMovie

What’s more fun than the endless possibilities of green screen video? Luckily, iMovie has the full capability to use green and blue backgrounds to transform footage, replicating your wildest movie dreams. Yes, at Storyblocks we love all these features that iMovie can offer.

Since iMovie is green and blue screen compatible, you have the ability to record over a green or a blue background, then “cut out” that background to reveal other footage you’ve taken or sourced from our library. For example, you could place a weather map over a broadcast. Or, you could put a dating app on a phone screen.

In this tutorial, we’ve unleashed asteroids onto a moving ship—and we’ll show you exactly how we created this cinematic space adventure.

Step 1. Import Media

First things first, you’re going to want to import any footage or audio you’ll be using for your project. Just go to File > Import Media or hit Command/Ctrl + I on your keyboard. For our space voyage, we used this green screen asteroid clip over this space shuttle footage.

Step 2. Drag Non-Green Screen Footage onto Track

After you import all of your footage into iMovie, you’ll want to drag the footage that was not recorded over a green screen onto the video track. This will be your bottom track.
