Remove Green Screen:
- In the viewer, tap "Auto" to automatically remove the green or blue from the clip.

Preview and Export: Preview your video, and when you are happy with the result, tap "Done" and then the "Share" icon to save or share your edited video.
In Summary:
Editing green screen videos on your iPhone is a straightforward process using the iMovie app. By adding the background first, then layering the green screen footage and applying the green/blue screen effect, you can easily create professional-looking videos directly on your mobile device.
