The Ping Pong behavior “ping-pongs” playback of a segment of the clip within the duration of the behavior. The ping-pong effect’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 Duration is set to 30, the first 30 frames of the clip play forward, then play in reverse, then forward, and so on until the end of the behavior. At the end of the behavior, normal playback resumes.
Adjust this behavior using the control in the Behaviors Inspector:
Duration: A slider that sets the duration of the ping-pong frames. The default value is 30 frames.
