356 Chapter 4 Using the Timeline
You can use this same technique to trim an object without automatically changing the
duration of masks, filters, or other applied effects.
To trim an object without changing applied effects:
m Press Command while you drag the edge of the object.
Slipping Objects in the Group Track
In addition to moving and trimming, you can slip certain objects directly in the group
bar. Any portion of the group that contains only one object can be slipped. Areas
where more than one object overlap cannot be slipped without expanding the group
and directly manipulating the individual objects.
To slip an object in the group track:
1 Option-click an area of the group where the object is located.
2 Drag to the right or left to use an earlier or later portion of the media without moving
the position or duration of the object.
You can only slip an object if there are unused frames in the source media associated
with that clip. For more information on slipping, see “
Slipping Clips ” on page 345.
Working in the Ruler
You can perform several types of functions using the ruler area of the Timeline. You can
move the playhead to a specific frame to view the project at a specific time. You can
also set In and Out points so that playback occurs only within the specified frames. In
addition, you can select a range of frames, so that you can delete, cut, or paste into the
selected frames.
