Green screen, also known as chroma key, is a technique used in video production to replace the background of a video with a different image or video. This technique is widely used in the film industry and can now be easily done with the help of video editing software like Filmora.
Filmora is a popular video editing software that is easy to use and has a range of features that can help you create professional-looking videos. I have been using this editing software for the last few years, and I can show you how to use the green screen in Filmora, even if you are a beginner.
I’m going to be using Filmora 12, but older version users should not feel left out as the software’s interface is more or less the same in the past few releases. With that said, let’s get started!

How to use the green screen effect in Filmora
1. Launch Filmora on your computer and then import at least two files: one green screen video and one background video. In this example, I have the Just Do It and American Flag videos.

2. Drag the background video to the timeline.

3. Then, drag the green screen video to the timeline on top of the background video.

4. Now, double-click on the green screen video.

5. Navigate to Video, then AI Tools, and then enable Chroma Key.

6. Normally, Filmora will detect a shade of green in the video and key that out automatically. But if it doesn’t, you can always manually select the color.

7. In some cases, you might want to play around with the Offset, Tolerance, Edge Thickness, and Edge Feather to make sure the effect looks clean and less noticeable. I can’t provide you with precise settings as every video is different. This is the area that you have to test yourself.

8. Once you are done, click OK.

9. There you have it! You just used a green screen in Filmora.

To make both videos blend nicely, not only do you have to clean the edges, but you also need to tinker with color grading. I have made a simple tutorial about color grading in Filmora here.
