Add video overlay effects in iMovie on iPhone
With iMovie, you can add video clips and photos as overlays, which appear on top of the main clip in the timeline. Overlays can be arranged in the same way as any other clip. There are four overlay options:
Cutaway: Adds the clip so that, during playback, the movie “cuts away” from the main clip in the timeline and shows the cutaway clip instead. The audio of the main clip is still heard.
Picture in Picture: Adds the clip so that, during playback, the clip appears in a smaller window, superimposed on the main clip in the timeline.
Split Screen: Adds the clip so that, during playback, the clip appears next to the main clip in the timeline. By default, the two clips appear side by side, equal in size, but you can swap the orientation of the clips so that one clip appears above the other.
Green/Blue Screen: Adds the clip so that, during playback, the clip appears with the green-screen or blue-screen parts of the clip removed, and the remaining parts of the clip are superimposed on the main clip in the timeline.
Use the viewer controls to adjust how your cutaway, picture-in-picture, split-screen, or green-screen or blue-screen clips appear during playback.
