Retiming behaviors modify timing and playback—slowing down, speeding up, looping, and reversing clips, among other effects. Although you can also control basic clip timing in the Properties Inspector, the Retiming behaviors are more flexible, letting you define which portion of the clip is modified by a timing change. Further, any timing changes made to a clip using the Inspector’s Timing controls are respected by the Retiming behaviors. For example, if you change the speed of a clip to 50% in the Properties Inspector and then apply a Retiming behavior, the Retiming behavior uses that half-speed clip as its source. (For more information about Timing controls in the Properties Inspector, see Retime media overview.)
There are 11 Retiming behaviors:
Flash Frame inserts a range of random frames into the playback of a clip.
Hold Frame freezes the frame at the behavior’s In point.
Loop replays a segment of a clip.
Ping Pong replays a segment of a clip backward and then forward.
Replay triggers playback of a clip segment that begins at a different frame in your project.
Reverse plays a clip or image sequence backwards.
Reverse Loop replays a segment of a clip in reverse.
Scrub moves a virtual playhead around a clip.
Set Speed changes the playback rate of a clip.
Strobe simulates the look of a strobe light or lower-frame-rate video.
Stutter randomly inserts hold frames, of random durations, into the playback of a clip.
