Chapter 9 Behaviors 351
Parameters in the Inspector
•
Duration: A slider that sets the duration of the ping-pong frames. The default value is
30 frames.
Replay
The Replay behavior resets the playhead at the beginning of the behavior to a specific frame,
then plays the clip normally from that frame. The clip plays back normally after the end of the
behavior. Use this behavior to trigger playback of the clip at different times, without making
multiple copies of the movie object.
Parameters in the Inspector
•
Start From: A pop-up menu that determines whether the replay starts from an absolute frame
number or an offset from the frame at the start of the behavior. There are two menu items:
•
Absolute Frame: Sets the replay to start at the frame specified in the Start Time parameter.
For example, if the behavior starts at frame 60 of the clip and Start Frame is set to 30, when
playback reaches frame 60, the clip starts playback over from frame 30.
•
Offset Frame: Offset the start frame of the replay. For example, if the behavior starts at frame
60 of the clip, and Start Frame is set to 30, when playback reaches frame 60, the clip starts
playback at frame 90. If Start Frame is set to –30, the clip starts playback over from frame 30.
•
Start Time: A slider that sets the start frame where the replay begins. The default is frame 1.
Reverse
The Reverse behavior plays the clip or image sequence backwards.
There are no parameters for this behavior.
Reverse Loop
The Reverse Loop 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.
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
lets you 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. Scrub does not affect clip audio.
Note: You can also apply Parameter behaviors to the Retime Value parameter in the Timing
controls for the clip object. The Timing controls are located in the Properties Inspector. Time
Remap must be set to Variable Speed to access the Retime Value parameter.
Parameters in the Inspector
•
Frame Offset: A slider that sets the offset of the virtual playhead.
•
Offset From: A pop-up menu that sets the position where the virtual playhead is offset. There
are two menu items: First Frame or Current Frame.
