Working with Video in Soundtrack Pro
Dragging a Clip Around the Multitrack Timeline
When you drag an existing clip around in the Timeline, the Multipoint Video HUD
displays the video frame at the start of the clip on the left, the video frame at the end
of the clip on the right, and the video frame at the current pointer position in the
middle. In the case of dragging multiple clips, the first frame of video would be from
the leading edge of the earliest clip in time and the last frame of video would be for
the trailing edge of the last clip in time.
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 do the following:
1
Click on the gun shot sound effect at the point where the large transient can be seen in
the waveform.
2
Drag the clip in the Timeline. Press V while dragging the clip.
3
Drag the clip 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.
