Scrub

Like the Scrub filter, the Scrub behavior moves a virtual playhead around a clip, allowing you to change the timing of the clip without moving it in the Timeline. Additionally, the Scrub behavior lets you animate the offset parameter using keyframes or Parameter behaviors, often with interesting results. Try applying the Oscillate behavior to the Frame offset, with the Offset From parameter set to Current Frame. Scrub does not affect clip audio.

Note: You can also apply Parameter behaviors to the Retime Value parameter in the Timing controls for the clip object. The Timing controls are located in the Properties Inspector. Time Remap must be set to Variable Speed to access the Retime Value parameter.

Adjust this behavior using the controls in the Behaviors Inspector:

Frame Offset: A slider that sets the offset of the virtual playhead.
Offset From: A pop-up menu that sets the position where the virtual playhead is offset. There are two menu items: First Frame or Current Frame.
