294 Chapter 4 Using the Timeline
Moving Objects to the Playhead
You can move an object to a new location in the Timeline by using the Move Selected
In (or Out) Point. This command automatically shifts the position of the selected object
to the current playhead position. This command can be used to move and align
multiple objects in one operation.
To move an object to the playhead:
1 Select the object you want to move.
2 Place the playhead where you want the object moved to.
3 Choose Mark > Move Selected In Point (or press {) to align the object’s beginning to
the playhead or choose Mark > Move Selected Out Point (or press }) to align the end of
the object to the playhead position.
Trimming Objects
Trim an object when you want to shorten or lengthen it. You can shorten or lengthen
either the beginning or end of the object by dragging from the left or right edge of the
object bar in the Timeline (the In and Out points).
You can also trim a clip by using the menu items and corresponding keyboard
shortcuts to change an object’s In and Out point. This allows you to trim multiple
objects simultaneously as well as make trimming changes on-the-fly while your project
is playing back.
You can only lengthen an object if there are existing unused frames in the source
media. When you click a clip, unused frames temporarily appear beyond the
boundaries of the object in a lighter color. If there is no room outside of the currently
used portion of the clip, no unused frames appear and you cannot lengthen the object.
