Retiming Behaviors
Retiming behaviors are applied to image sequences, QuickTime movies, and clone layers
in order to change their timing. Retiming effects include creating hold frames, changing
playback rate, reversing a clip, creating stutter or strobe effects, and so on.
Important: Retiming behaviors can only be applied to QuickTime movies, image
sequences, or clone layers. In other words, a Retiming behavior cannot be applied to a
particle emitter, but it can be applied to an instance of the particle emitter. For more
information on cloning layers, see Making Clone Layers.
Retiming Behaviors Versus Timing Controls in the Inspector
When a clip is selected, a group of Timing parameters appears in the Properties tab of
the Inspector. These controls allow you to do 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 beauty of the Retiming behaviors is that
you can define which portion of the clip is affected by the behavior. 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.
The following sections cover the Retiming behaviors:
• Flash Frame
• Hold Frame
• Loop
• Ping Pong
• Replay
• Reverse
• Reverse Loop
• Scrub
• Set Speed
• Strobe
• Stutter
Flash Frame
This behavior randomly inserts a user-defined range of random frames (adjacent to the
current frame) into the playback of a clip.
