Apple Soundtrack Pro 3 - Manual (Page 364)

For example, if you wanted to synchronize a gunshot sound with the frame in the video
when the flash from the gun is visible, you would first click the gunshot sound effect at
the point where the large transient can be seen in the waveform. Next, you would drag
the clip in the Timeline, pressing V while dragging, until you see the flash in the center
frame.
Resizing a Clip in the Multitrack Timeline
When you resize a clip in the Timeline, the Multipoint Video HUD displays the video frame
at the start of the clip and the video frame at the end of the clip. As you resize one edge
of the clip, that frame updates.
Nudging a Clip in the Multitrack Timeline
When you use the nudge keys to nudge a clip, the Multipoint Video HUD displays the
video frame at the start of the clip and the video frame at the end of the clip.
Horizontally Moving an Envelope Point in the Timeline and File Editor Project View
When you move an envelope point horizontally, the Multipoint Video HUD displays the
video frame at the current envelope point position. If you select multiple envelope points,
two or three frames are shown: one for the first envelope point, one for the last envelope
point, and one for the envelope point you are dragging, if it is not the first or last point.
Time Stretching in the File Editor
When you use the Time Audio Stretching tool, the Multipoint Video HUD displays a single
frame of video that follows the pointer location.
Dragging the Cycle Region
When you modify either end of the Cycle Region, the Multipoint Video HUD displays the
video frame at the start of the Cycle Region and the video frame at the end of the cycle
region. You can quickly remove the Cycle Region at any time by pressing Option-X.
Dragging Markers
When you drag a single marker, the Multipoint Video HUD displays the video frame at
the marker position. When you drag two markers, the Multipoint Video HUD displays the
video frames at both marker positions. When you drag three or more markers, the
Multipoint Video HUD displays three video frames: the first marker, the marker being
dragged, and the last marker.
