Trim an object and snap its In or Out point to neighboring objects
• In Motion, press and hold the Shift key as you drag the edge of a bar in the track area.
Vertical lines appear in the track, corresponding to the In and Out points of other bars.
The active bar snaps to these lines as you drag.
Trim one or more objects via the Mark menu
1. In Motion, select one or more objects to trim.
2. Place the playhead at the frame where you want the new In or Out point.
3. Choose Mark > Mark In (or press I) or Mark > Mark Out (or press O) to set a new In point
or Out point.
All selected objects are trimmed to the new point.
Trim an image or video layer without trimming its applied effects objects
You can trim a layer without affecting the duration of its applied effects objects (masks,
filters, and so on).
• In Motion, press and hold the Command key while you drag the edge of the image or
video clip.
The object is trimmed independently of its applied effects objects.
Slip video layers in the Timeline in Motion
Slip a video layer when you want to use a different section of your source clip without
changing the layer’s duration or where it appears in the Timeline.
Important: Slipping is only possible after you’ve trimmed a video layer’s timebar.
For example, if you have a shot of a door opening that is three seconds long and you want
to trim it by one second, you can use the Slip function to select which one-second section
to use: the first second as the door leaves the jamb, the next second where the door
swings open, or the last second where it bangs against the wall.
As with trimming, when you slip a video layer in the track area, Motion provides a visual
representation of how much additional footage is available in the object’s source clip: A
dimmed extension on either end of the bar indicates that unused frames exist in the source
video clip. You can only slip a bar as far as the existing unused frames in the source media.
