Add clips to your trailer

To open a trailer, double-click it in Projects view.
In the Storyboard pane, click the placeholder well you want to fill.
The item’s placeholder image and label (for example, a person’s name) suggest the type of clip you should add, and the time stamp on the left side of each well indicates the length of video needed.
Do one of the following:
In the browser, click the clip you want to add to the placeholder well.
The clip is added to the trailer, starting from the point where you clicked.
Drag a clip from the browser to a placeholder well.
In the browser, select a range.
The clip is added, starting from the first frame of the selected range.

Fine-tune a trailer clip
You can fine-tune a clip you’ve added to your trailer using a set of controls that appear when you move the pointer over the clip.
In the iMovie app
on your Mac, open a trailer and move the pointer over a clip in any of the trailer panes to make the clip controls appear.

Do any of the following:
Turn the clip’s audio on and off: Click the speaker icon in the upper left.
Delete the clip from the well: Click the curved arrow icon in the upper right.

A turtle or rabbit icon appears only if the clip has been slowed down or sped up. For more information, see Change clip speed in iMovie on Mac.

Add, swap, and delete clips using the trailer’s shot list
