With the Normal tool selected, drag either end of an event.

The event edge will snap to grid lines or markers if Enable Snapping is selected or will snap to frame boundaries if Quantize to Frames is selected; you can hold the Shift key while dragging to temporarily override the current snapping setting.

If you drag the end of the event past the end of the media file, the event will repeat if the Loop event switch is turned on; if the switch is turned off, silence is drawn.

With this method, you can quickly jump through your project and adjust cuts until they’re perfectly synchronized. If you have an external multimedia controller, it’s even easier.

1. If you want downstream events to ripple as you trim, click the Auto Ripple button to turn on Auto Ripple mode.

2. Select the event you want to trim.

3. Press [ or ] (or 7 or 9 on the numeric keypad) to move the cursor to the event edge you want to trim. [ or 7 selects the beginning of an event or moves to the previous event edge. ] or 9 selects the end of the event or moves to the next event edge. A red bracket is displayed to indicate which event edge will be trimmed.

   

4. Use the 1, 3 and 4, 6 keys on the numeric keypad to trim the current event edge:

5. Press 1 to trim one video frame left, or press 3 to trim one video frame right (or hold Ctrl+Shift+Alt while rolling the mouse wheel).

6. Press 4 to trim one screen pixel left, or press 6 to trim one pixel right (or hold Ctrl+Shift while rolling the mouse wheel). Depending on the current zoom level, the trim duration will vary.

7. Hold Ctrl while pressing 1 to time compress one frame left, or press 3 to time stretch one frame right.

8. Hold Ctrl while pressing 4 to time compress one pixel left, or press 6 to time stretch one pixel right.

9. Hold Alt while pressing 1 to slip trim (the media moves with the event edge) one frame left, or press 3 to slip trim one frame right.

10. Hold Alt while pressing 4 to slip trim one pixel left, or press 6 to slip trim one pixel right.

11. Hold Ctrl+Alt while pressing 1 to slide a crossfade or transition one frame left, or press 3 to slide one frame right.

12. Hold Ctrl+Alt while pressing 4 to slide a crossfade or transition one pixel left, or press 6 to slide one pixel right.

Pressing 5 on the numeric keypad exits edge-trimming mode. If you are not in edge-trimming mode, 1, 3, 4, and 6 on the numeric keypad to nudge events on the timeline by frame (1 and 3) or by pixel (4 and 6).

5. Repeat steps 3 and 4 as necessary.

Hold Ctrl+Alt while dragging the event edge between two events. The mouse pointer is displayed as a an . The edges of the selected event and the adjacent event are trimmed simultaneously in the direction you drag.

1. Drag to make a timeline selection (or hold down the Shift key and use the arrow keys to make the selection).

2. From the Edit menu, choose Trim. All data outside of the selection is deleted.

The Resample and stretch quality setting on the Audio tab of the Project Properties dialog determines the quality of processing when time-stretching audio events.

To change the duration of an event without changing its contents, hold Ctrl while dragging the right or left edge of an event. The mouse pointer is displayed as a . You can use the Time stretch/pitch shift controls in the Event Properties dialog to specify whether the pitch of an audio event will be preserved while stretching.

As you drag the edge of a video event, a zigzag line is displayed between video frames to show you that the event has been stretched:

If Active Take Information is selected from the View menu, audio events will display a percentage in the lower-right corner of the event to indicate the playback rate after stretching. If the media has a known tempo, the effective playback tempo (after stretching) is listed in parentheses after the stretch amount.

Hold Alt while dragging the right or left edge of an event. The cursor is displayed as a .

As you drag the event edge, the opposite edge of the event will remain fixed, trimming the media from the edge you drag.

Tips:

• Hold Alt+Shift while dragging any portion of an event to slip-trim the right edge. The left edge of the event will remain fixed on the timeline, and the media is slipped past the left edge of the event.
  This slip mode is useful when you want to slip an event without changing its last frame.

• Hold Hold Ctrl+Alt+Shift and drag an event to split it at the point you click and trim the event in the direction you drag (eraser mode).

  Holding the Shift key temporarily overrides snapping if it is enabled. Release the Shift key while dragging to snap the event to available snap points.
   

• If you want to slip all of an event’s takes when slipping media, choose Slip All Takes from the Options menu.
