Add video overlay effects in iMovie on iPhone

With iMovie, it is possible to include video clips and photographs in overlays displayed above the central clip on the timeline. Overlays can be organized similarly to any other video clip. There are four options for overlays:

  • CutawayAdds an image to its clip so that, when played back, the film “cuts away” from the central clip within the timeline and displays the cutaway video instead. The original audio clip is heard.
  • Image in PictureAdds the video so that the video appears on a smaller screen during playback and is superimposed on the primary clip on the timeline.
  • Split ScreenAdds to the video so that the clip appears alongside the central clip on the timeline during playback. By default, both pins will appear together, identical in size. However, you can change the direction of the clips so that one appears over the other.
  • Green/Blue ScreenAdds the clip so that during playback, the clip is shown with the blue or green screen sections of the pin taken out and the other parts of the clips are superimposed over the central clip on the timeline.

Utilize the controls for your viewer to alter how your cutaway, picture-in picture split-screen, blue-screen or green-screen videos appear when playing back.
