Green Screen (Chroma Key)

You can use the Green Screen (Chroma Key) tool to make a color range in a video clip or image in a higher track on your timeline transparent, so the video clip or image underneath it can be seen in place of that color range. You can use this feature to change the background of a clip and make it look like you're a superhero flying through the sky or an explorer on top of a mountain.

Green Screen works best if you have a solid-colored background to make it transparent, preferably a color that the subjects in the video are not also wearing. The most popular choice is bright green. Here's how to use the Chroma Key/Green Screen tool in Filmora for Mac.
