The Loop behavior loops a segment of the clip within the duration of the behavior. The loop’s starting frame is derived from the start frame of the behavior. For example, if the behavior is applied at the start of a clip, and Loop Duration is set to 30, the first 30 frames of the clip loop repeatedly until the end of the behavior. At the end of the behavior, normal playback resumes from the frame at the end of the loop duration.
Adjust this behavior using the control in the Behaviors Inspector:
Loop Duration: A slider that sets the duration of the looped frames. The default value is 30 frames.
