1. Open the clipping APP, click the+sign in the middle, and start to create

2. Then click the black field in the material library to find the third transparent background to add

3. Then find the background in the menu bar below, find the canvas color, and choose the color as green (as long as it is easy to dig)

4. Then put yourself.

5. Then add a combination animation to the characters, such as 3D crystal, so that a simple green screen material is ready, and you can directly add material color clipping to the video next time after exporting it for standby.
