To delete time when there is no audio or MIDI data in the area you want to delete
(or if there is data, but you like to drag and drop):
1. Set the Snap to Grid value to the unit of time you want to delete. For example,
if you want to delete whole measures, set the Snap to Grid value to a whole
measure.
2. In the Track view, select the clips you want to move.
3. Drag one of the selected clips to its proper destination—the Drag and Drop
Options dialog box appears.
4. Choose options and click OK.
All the selected clips move by the amount that you dragged the mouse.
Stretching and Shrinking Events
The Process-Length and Process-Fit to Time commands can be used to stretch
or shrink a portion of a project. Process-Length lets you stretch or shrink the
selection by a fixed percentage and makes the adjustment by altering the
individual events. A value of 200 percent, for example, stretches the selection to
twice its original length, while a value of 50 percent shrinks the selection to half
its original length.
Process-Fit to Time stretches or shrinks the selection so that it ends at a specific
time, expressed in either measure:beat:tick (MBT) or
hours:minutes:seconds:frames (SMPTE) format. This command gives you a choice
of modifying the events or modifying the underlying tempo. This is useful when
you want a portion of a project to have an exact length. The start time of the
selection does not change, but the end time is altered as necessary to fit the
required time interval.
Both of these commands offer the option to stretch audio clips along with the MIDI
information. Sometimes you don’t want to adjust the speed of your audio.
Here are some examples:
• If your project contains background music and a voice-over, you might want to
change the tempo of the background music without altering the voice-over
• If you’re trying to modify the speed of some MIDI tracks to match a sampled
drum groove, you want to leave the audio unchanged
• If your audio consists solely of sound effects, you most likely do not want to
adjust them
Audio can be stretched or condensed up to a factor of 4 (e.g., it can be shrunk to as
little as 25 percent of its original length, or expanded to as much as 400 percent of
its original length).
