456 Chapter 5 Using Behaviors
Reverse
This behavior plays the clip or image sequence in reverse.
HUD Control
There are no parameters for this behavior.
Parameters in the Inspector
There are no parameters for this behavior.
Reverse Loop
This behavior loops a segment of the clip in reverse within the duration of the
behavior. If Loop Duration is set to 30 and the behavior begins at frame 1, frames 1-30
are played in reverse, then frames 31-60 are played in reverse, frames 61-90 are played
in reverse, and so on.
∏
Tip: To achieve a nice stutter effect, set Loop Duration to 2.
HUD Control
The HUD contains the Loop Duration parameter.
Parameters in the Inspector
Loop Duration: A slider that sets the duration of the looped frames to be played in
reverse. The default value is 30 frames.
Scrub
Like the Scrub filter, the Scrub behavior moves a virtual playhead around a clip,
allowing you to change the timing of the clip without moving it in the Timeline.
Additionally, the Scrub behavior allows you to animate the offset parameter using
keyframes or parameter behaviors, often with interesting results. Try applying the
Oscillate behavior to the Frame offset, with the Offset From parameter set to Current
Frame.
Note: You can also apply parameter behaviors to the Retime Value parameter in the
Timing controls for the image itself. The Timing controls are located in the Properties
tab. Time Remap must be set to Variable Speed in order to access the Retime Value
parameter.
HUD Control
The HUD contains the Frame Offset and Offset From parameters.
Parameters in the Inspector
Frame Offset: Sets the offset of the virtual playhead.
Offset From: Sets the position from which the virtual playhead is offset. Values can be
selected from First Frame or Current Frame.
