Do one of the following:
m To move an object forward a specific number of frames, select the object, type a plus sign (+)
followed by the number of the frames you want to move, then press Return.
m To move an object backward a specific number of frames, select the object, type a minus sign (–)

Trim objects
Trim an object when you want to shorten or lengthen its duration in the Timeline. You can
shorten or lengthen the beginning or end of the object by dragging from the left or right edge
of the object bar (the In and Out points). You can also trim an object (change its In and Out
points) by using menu commands and corresponding keyboard shortcuts. You can trim multiple
objects simultaneously, and you can trim on the fly while your project is playing back.
Note: Video and audio objects cannot be trimmed to be longer than the duration of their
source media. To extend a video or audio object beyond the duration of its source media, you
must change the object’s End Condition to Loop, Ping Pong, or Hold in the object’s Properties
Inspector. This limitation does not apply to other objects, such as still images, cameras, text,
and shapes, all of which you can extend without restriction. You can also change the effective
duration of a clip without adding or removing frames by changing the clip’s playback speed. For
more information on the Timing controls, see
Retiming overview on page 246.
