Chapter 4 Using the Timeline 305
Disconnecting the Layer Track From its Contents
You can modify the layer bar to be longer or shorter than the contents of the layer. For
example, you might shorten a layer track to hide a section of the objects within it.
Objects that extend beyond the boundaries of the layer bar (the thin blue bar at the
top of the layer track) are not displayed in the Canvas.
To change the length of the layer independently from the objects within it:
m Press Command, then drag the edge of the layer track.
Only the thin blue layer bar is trimmed.
Note: Once you manually change the length of the layer bar, it is no longer
automatically updated as you add or modify the objects within it. To restore automatic
updating, realign the layer bar with the right edge of the last clip in the layer.
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 Layer Track
In addition to moving and trimming, you can slip certain objects directly in the layer
bar. Any portion of the layer that only contains one object can be slipped. Areas where
more than one object overlap cannot be slipped without expanding the layer and
directly manipulating the individual objects.
