Using the Speed Tool

The Speed tool provides a quick method for adjusting the speed of two adjacent clips in the Timeline by “rolling” their shared edit point. You can also adjust the speed of a single clip by dragging its In or Out point with the Speed tool.

Dragging an edit point with the Speed tool slows down one clip while speeding up the adjacent clip. No clips move in the Timeline as a result; only the edit point between the two clips moves. This is a two-sided edit, meaning that two clips’ edit points are affected simultaneously: the first clip’s Out point and the next clip’s In point are both adjusted. However, no other clips in the sequence are affected.

Note: When you adjust an edit point with the Speed tool, the overall duration of the sequence stays the same, but both clips change their speed and their duration. As with a roll edit, one clip gets longer and the other clip gets shorter to compensate.

To adjust the speed of two adjacent clips in the Timeline using the Speed tool
  1. Select the Speed tool in the Tool palette (or press SSS).

  2. Select an edit point between two clips.

    If linked selection is on, the edit points of linked items are also selected. For more information, see Controls That Affect Trim Edits.

  3. Drag the edit point left or right.

    As you drag, the clips display their adjusted speeds as a percentage of their default speeds.

    In the example above, the clip on the left is being adjusted to nearly twice its original speed while the clip on the right is being slowed to 82% of its original speed.

    Additionally, the Canvas shows a two-up display with the Out point of the outgoing clip on the left and the In point of the incoming clip on the right (see also About the Two-Up Display in the Canvas).

    Note: Optionally, you can hold down the Shift key as you drag. This will adjust the speed of the clip on the selected side of the edit point and perform a roll edit on the other clip. For more information about roll edits, see Performing Slip, Slide, Ripple, and Roll Edits.

The Speed tool adjusts both the video and any linked audio. However, variable speed settings (speed segments) applied to a video clip item are not applied to the audio items linked to it. Audio and video sync is lost when you apply a variable (segmented) speed change.

To adjust the speed of a single clip in the Timeline using the Speed tool
  1. Select the Speed tool in the Tool palette (or press SSS).

  2. Select either the In point or the Out point of the clip.

    If linked selection is on, the edit points of linked items are also selected. For more information, see Controls That Affect Trim Edits.

  3. Drag the edit point left or right.

    As you drag, the clip displays the adjusted speed as a percentage of its default (original) speed.
