Make finishing touches to a trailer in iMovie on iPhone

With your trailer project open, you can play the trailer at any time to watch it from the beginning or to check your work in progress.

1. In the iMovie app on your iPhone, open a trailer storyboard project.

2. Do any of the following:

   • Play the trailer in the viewer: Tap the Play button below the viewer. In the Outline tab, the trailer plays from the beginning; in the Storyboard tab, the trailer plays from the playhead (the red vertical line). Tap the Pause button to stop playback.

   • Play the trailer from the beginning in full-screen view: Tap the Play Full Screen button . If the playback controls aren’t showing, tap the screen. Tap Done to stop playback.

   • Play only the selected portion of the video: Tap the Play button at the bottom of the screen. Tap the button again to stop playback.

You can adjust which portion of your video clip appears in a placeholder if the video clip lasts longer than the designated time for that item. You can also turn on audio for the clip (it’s off by default).

   The entire video clip containing the selected portion of video appears, with the selected portion outlined in yellow.

4. Do any of the following:

   • Select a new portion of the video: Drag the clip left or right to make a new selection.

     The viewer shows the first frame of the selection as you move the clip, so you can see precisely where the selection begins.

     Note: If you recorded into a photo placeholder, you can’t turn on audio.
