Trimming Behaviors
When you apply a behavior to an object, the duration of the behavior in the Timeline
defaults to the duration of the object to which it’s applied.
The default duration of a
behavior matches the
duration of the object to
which it is applied.
A behavior can be modified to limit the duration of its effect. For example, if you apply
the Spin behavior to a replicator layer, by default that replicator spins around for its entire
duration. If you trim the Out point of the Spin behavior, the spinning stops at the new
position of the Out point.
A tooltip indicates the
new position of the Out
point.
To change the duration of a behavior in the Timeline
1 Move the pointer to the In or Out point of any behavior in the Timeline.
2 When the pointer changes to the trim pointer, do one of the following:
• Drag the In point to delay the beginning of the behavior’s effect.
• Drag the Out point to end the behavior’s effect prior to the end of the object.
Note: When you drag the In or Out point of a behavior, a tooltip appears and displays
the new location and duration of the In or Out point.
