•
Wriggle Offset: A slider that offsets the sequence of random values when you want to apply
the same Wriggle behavior to multiple objects. By offsetting each object’s version of the
Wriggle behavior, you can prevent objects from moving in sync.
•
Noisiness: A slider that adds an additional overlay of random variance to the Frequency you’ve
set. Higher Noisiness values result in more erratic variations in the affected parameter.
•
Link: A checkbox, available when you apply the Wriggle behavior to a two-dimensional
parameter (such as Scale) or three-dimensional parameter (such as Position) that consists
of X, Y, and/or Z values. Turn this checkbox on to keep the behavior’s effect on each
value proportional.
•
Affect Subobjects: A checkbox, available when the Wriggle behavior is applied to a parameter
of the Sequence Replicator behavior. When Affect Subobjects is selected, each object has a
different wriggle behavior. When Affect Subobjects is deselected, each object undergoes the
same animation.
•
Random Seed: A button that picks a new random seed number. This number is used to
generate new sequences of values, based on the other parameters of this behavior.
•
Start Offset: A slider that delays the beginning of the behavior’s effect relative to the first frame
of its position in the Timeline. Adjust this parameter to make the behavior start later. This
parameter is measured in frames.
•
End Offset: A slider that offsets the end of the behavior’s effect relative to the last frame of its
position in the Timeline, in frames. Adjust this parameter to make the behavior stop before
the actual end of the behavior in the Timeline. Using this slider to stop the effect, instead of
trimming the end of the behavior in the Timeline, freezes the last random value generated
by this behavior for the remaining duration of the object. Trimming the end of the behavior
resets the parameter to its original value.
•
Apply To: A pop-up menu that shows the parameter affected and can be used to reassign the
behavior to another parameter.
Retiming behaviors
Retiming behaviors overview
When a clip is selected, a group of Timing parameters appears in the Properties Inspector. These
controls adjust some of the same effects as the Retiming behaviors, such as slowing down or
speeding up, looping, or reversing a clip. However, the Timing controls affect the entire clip. The
Retiming behaviors, on the other hand, let you define which portion of the clip is modified by
a timing change. Any timing changes made to a clip using the Inspector’s Timing controls are
respected by the Retiming behaviors. For example, if you changed the speed of the clip to 50%
in the Timing parameters, a Retiming behavior uses that half-speed clip as its source. For more
information on Timing controls in the Inspector, see
Retiming overview on page 246.
For a description of each Retiming behavior, see the behavior list in the Help table of contents
(the sidebar to the left of this window).
Flash Frame
The Flash Frame behavior inserts a user-defined range of random frames (adjacent to the current
frame) into the playback of a clip.
