After you click Create Trailer, iMovie takes you to a screen with two tabs, labeled Outline and Storyboard. Tap the Outline tab.

iMovie lists the info it wants using dummy text: Name, Cast, Studio, and so on. To change the placeholder text, tap it. iMovie brings up the keyboard so you can type in your own info. Tap Done when you finish.

Some questions, like the gender of your actors, require you to choose from a drop-down menu. Tap the item to call up the menu.

Other questions, like how many actors appear in your movie, need a number for an answer. Tap the + and – buttons to add or subtract items to and from the list (see Figure 23-2).

Once you fill in the outline, tap the Storyboard tab to go to the trailer’s timeline, where you’ll add video clips, photos, and titles to your preview-in-progress.

To add video or photos to a trailer, tap any empty frame to launch the Media screen. To see a particular type of media, tap Video or Photos in the toolbar. You can use the media selection tools described on Find Audio and Photos for video (so you can sort your footage) and The Photo Library for photos (to get access to all your device’s photo folders).

Choosing the right video clip is a little tricky, because you want to display just the right moment in the few seconds the trailer gives you. First, select a clip. That calls up the yellow highlight box with the edit handles, but this time the handles are immobile—you can’t drag them to change the clip’s length—remember, trailers use clips of fixed duration. But you can drag the entire yellow box, and that’s the trick to getting the shot you want: Drag the box until the right section of the clip sits within it (Figure 23-4).

As you drag the border around, iMovie previews the clip in the viewer. Tap to play the selection as it will appear in your trailer. When you’re satisfied, tap to add your selection to the storyboard.

For photos, the selection process is simple: Find the photo you want, and then tap it to add it to the storyboard.

Perhaps the coolest thing about making trailers on your iPad, iPhone, or iPod Touch is not having to capture a frame of movie footage before you build your trailer. You can start a new trailer project and film the shots as you go.

When you tap a frame to add a shot, choose Camera instead of Video or Photos. iMovie displays a special camera screen above your storyboard (see Figure 23-5). Use this camera to film a shot, and iMovie saves it straight to the trailer. Talk about on-the-fly editing! iMovie at its best, really.

Figure 23-4. When you select a clip for your trailer, iMovie limits how long it plays. Drag the yellow selection border to choose the right moment.

Figure 23-5. Use this special camera screen to shoot footage or photos and save them straight to your trailer. (The top image shows the iPhone version, and the bottom image is from an iPad.)

The video version of the camera has a few unique features. It displays the destination frame for your footage right below the camera, and it lists the clip’s duration in the frame, so you can better plan your shot.

When you hit the Record button, the camera counts you in and displays an elongated destination frame (Figure 23-6). That frame has the trailer shot at its core, and room on either side that serves two purposes: It lets you prepare to shoot—as the red “playhead” moves across the frame, you can see where your trailer shot goes “live.” And second, it gives you some extra footage in case you need to fine-tune the shot later (read on).

Figure 23-6. When you record video, iMovie counts you in and displays an elongated destination frame. As you can see from the frame, iMovie films extra footage on either side of the core trailer shot so you can fine-tune the clip later.

The photo version of the trailers camera is really simple. Just point and shoot. The photo you take fills the trailer frame.

The video clips and photos you put in a trailer frame will sometimes be off a little. Video clips might be off because of timing, with the wrong moment displayed in the frame. Photos might be off because the Ken Burns effect iMovie automatically applies doesn’t look quite right. You can fix both issues easily.

If, after you shoot a clip, your timing is a little off, you don’t have to retake the shot. Tap the frame that has the errant footage. iMovie opens the Edit Shot window. It displays the clip as a filmstrip, with the trailer shot highlighted in yellow. To adjust the shot, drag the filmstrip until the section you want sits within the yellow box (Figure 23-7).

You can also unmute a clip here, and delete it if you want to start over.

The Edit Shot screen for trailer photos is different (Figure 23-8). iMovie applies the Ken Burns effect to photos, so the edit screen lets you set the start and end points for the zoom and pan.

iMovie displays the image in a yellow highlight box. Just under that, tap Start and then use the preview screen above to position (by dragging) and zoom in on (by pinching) the photo. When you finish, tap End and do the same thing. iMovie uses the difference between the two positions to determine how to apply the Ken Burns effect. (For a description of the process, see Duration.) Press to preview the shot. Tap Done when you finish, or the trash can to delete the photo and start over.

Figure 23-7. To edit a trailer clip, drag the filmstrip around to position it at just the right moment. You can also mute or unmute the clip using the speaker button. (iMovie mutes trailer clips by default.) Tap to preview the shot before you tap Done. Tap the trash can if you want to delete the footage and start over with a different shot.

Figure 23-8. Editing a trailer photo is a matter of dragging and pinching it to set its start and end points for the Ken Burns effect. Press to preview your work, or the trash can to delete the photo and start over.

Part of what makes trailers so great are the impressive titles Apple designed for them. They make your movie look like you spent a lot of money on animators and designers. The fact that you can type in whatever you want and have it look so good is amazing.

To change the text of a title, tap it in the storyboard (be sure to tap the title itself, not the frame under it). iMovie launches the keyboard (Figure 23-9). Type in the new text and see what it looks like in the preview window. Tap Done to save your changes.

Figure 23-9. To change a trailer title, tap it in the storyboard. Use the keyboard to type in new text, and the preview window shows what it will look like. Tap Done to save your changes.

Be sure to take the time to update all the text in the trailer. Although iMovie provides placeholder copy, odds are you can come up with something better that will make the trailer your own.
