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

” on page 283.

Flash Frame

This behavior randomly inserts a user-defined range of frames (adjacent to the current
frame) into the playback of a clip.

HUD Control
The HUD contains the Random Frames, Frame Range, Duration, and Random Seed
parameters.

Parameters in the Inspector

Random Frames: A slider that sets the probability that a frame within the duration of
the behavior is replaced with a random frame. When this value is set to 0, no random
frames are inserted. When set to 100, every frame is random. The default value is 10%.

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 slow or speed, loop, or reverse a clip; however, they 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 “
