Time to start cutting! In iMovie, you’ll see that the program is made up of three main windows: the project library, the viewer and the timeline. The project library is where you will keep your videos while you edit, the viewer is where you will view these videos as you edit and the timeline is where you will make edits to the videos.
Whenever you click on a clip in your project library, iMovie selects and highlights a four second portion of that video. To lengthen or shorten the selected portion, drag on the yellow tabs on either end of the highlighted section. To bring the clip into your timeline, click the highlighted portion of the clip and drag it into the timeline. Since we’re making a 5x5, each of the five clips we use should be five seconds long. Once all of your clips are in the timeline you can re-arrange them by dragging them around. It’s that simple! And be creative! Don’t worry about making any irreversible mistakes while you edit, though. The videos you edit in iMovie are only copies of your original videos. Pretty nifty, huh?
