How to Add a Green Screen and Change Video Background in iMovie

Once upon a time, you had to use a physical green screen to easily switch up the backgrounds of videos — but low and behold, we have an option that just made turning any video background into a green screen possible. Here’s how you can DIY your green screen and change a video background with iMovie.

DIY Green Screen 

So before you can start switching up your background in iMovie, you have got to get a green screen behind it. 

What once required a professional setup and studio is now possible in the comfort of your home. To DIY your green screen simply:

1. Film a video with a relatively plain background and/or one with a lot of contrast to the subject matter you’re filming.

2. Once you have your mp4 file, hop on over to Unscreen.

3. Drag and drop your video right here:

4. While your video is uploading, go ahead and select the tab ‘color’ -> ‘green screen’ — you will instantly see exactly what your video will look like with the green screen as a background.

5.Then go ahead and hit ‘Process with pro’ to download the full video with a green screen. 

6. To change the background with iMovie and get the best possible result, you will want to select the mp4 Output.
