You can scrub audio using either the Scrub tool or the playhead. For information about
scrubbing, see
Scrubbing Audio Files .
Scrubbing Video
In projects containing a video file, the video scrubs in the Video tab in sync with the audio
as you scrub in the Timeline or the File Editor tab.
As you drag audio clips, markers, envelope points, or other items in the Timeline or the
File Editor tab, the video scrubs at the start point of the item being dragged. Dragging
multiple items scrubs the video at the start point of the item under the pointer.
You can use the Multipoint Video HUD as a visual tool for precisely positioning sound
effects and other audio clips in a video program. For more information, see
Scrubbing
and Spotting with the Multipoint Video HUD .
Controlling Playback with the Transport Controls
You use the transport controls to control playback of your project. The transport controls
let you set the playhead to various points in time, start and stop playback, activate the
cycle region, and start a recording session to record your own audio.
