For Seniors: Edit Movies with iPhone 4S iMovie App
A version of the iMovie app is available for the iPhone 4S. After you capture a video, you can use iMovie to edit it. If you want to edit video you've already captured, start by purchasing iMovie from the App Store (it costs $4.99).
Tap the iMovie app icon on the Home screen to open it.
On the screen that appears, tap the New Project button to begin a new movie project.
Tap the Insert button.
Any videos you’ve taken are listed at the top of the screen.
Double-tap a video to open it.
To scroll through your video, flick your finger on the storyboard. Wherever the red line sits is where your next action, such as playing the video or adding a transition, begins.
To add one video to the end of another, double-tap another clip in the list of media.
The clip appears to the right of the first one in the storyboard.
If you want to add music to your videos, tap the Settings button and tap to turn Theme Music on.
If you wish the music to repeat, tap Loop Background music (a quick and easy way to add a musical track to your video).
To record an audio narration, scroll to the point in the movie where you want it to be heard and tap the Microphone button.
Tap the Record button, tap Record, wait for the countdown to finish, and then record. When you’re done recording, tap Stop.
In the options shown, tap Review to hear your recording.
Accept to save the recording, or Discard or Retake if you’re not completely happy with it. If you accept the recording, it appears below the storyboard at the point in the movie where it will play back.
To quickly return from iMovie to your camera, perhaps to capture more footage, tap the Video Camera button.
You can tap the Settings button to open a menu that lets you make settings for special effects that allow you to fade your movie in or out at the beginning and end.
