Source Start Frame Offset: Offsets the start frame chosen in the Source Start Frame
parameter over the pattern. At their origin, the elements play the animation from the
frame specified in the Source Start Frame parameter. Each step away from the origin
advances the start frame by the offset amount. This parameter only appears if Random
Start Frame is turned off.
Hold Frames: Sets the number of times each frame of the source movie is repeated
during playback. The larger the Hold Frames value, the slower your playback.
Hold Frames Randomness: Varies the number of frames to “hold.”
Animating Replicator Parameters
Most of the replicator and replicator cell parameters can be animated with keyframing
or using Parameter behaviors. If you animate the replicator’s shape-specific parameters
such as Radius, Twists, and Offset (of a Spiral replicator), the pattern on which the
elements are built is animated, not the elements themselves. To animate the elements
of the pattern, you keyframe the parameters in the Cell Controls group (or the
Replicator Cell tab).
Keyframing the replicator parameters (or using Parameter behaviors) animates all
elements in the replicator symmetrically. To animate the individual elements in
sequence over time—without having to create keyframes—use the Sequence Behavior,
described in “
Using the Sequence Replicator Behavior
” on page 821. To animate the
replicator using Basic Motion or Simulation behaviors, see “
Important:
If you apply a Simulation behavior, or a Throw or Spin behavior to a
replicator with animated parameters, some of the keyframed parameters are ignored.
For more information on using behaviors with the replicator, see “
Rectangle replicator shape with Origin set to
Top and Source Frame Offset set to 0
When Source Frame Offset is set to 120, the
effect of the offset occurs from the origin of the
cells.
