Play a clip backward, then forward

  1. In the Timeline panel, click on the Clip Effect menu and choose Time Remapping > Speed. (The Clip Effect menu appears next to the filename of every clip in a video track. You might have to zoom in to make enough room in the clip to display it.)

    A horizontal rubberband that controls the speed of the clip appears across the center of the clip. The clip is shaded in contrasting colors above and below the 100% speed demarcation. A white speed control track appears in the upper portion of the clip, just below the clip title bar.

  2. Ctrl-click (Windows) or Command-click (Mac OS) on the rubberband to create a speed keyframe .
  3. Ctrl-drag (Windows) or Command-drag (Mac OS) a speed keyframe (both halves) to the place where you want the backward motion to end. A tool tip shows the speed as a negative percentage of the original speed. The Program monitor displays two panes: the static frame where you initiated the drag, and a dynamically updating frame that reverse playback will return to before switching to forward speed. When you release the mouse button to end the drag, an additional segment of the same duration as the segment you just created is added for the forward playback portion, and an additional speed keyframe is placed at this second segment’s end. Left-pointing angle brackets  appear in the speed-control track, indicating the section of the clip playing in reverse.
    The segment plays backward at full speed from the first keyframe to the second, then forward at full speed from the second to the third keyframe, returning to the frame at which the backward motion began. This is called a palindrome reverse.
    To create a segment that plays in reverse and doesn't return to forward playback, use the Razor tool to remove the segment of the clip with the forward playback section, or remove it with the Trim tool.

  4. (Optional) To create a speed transition for any part of the change in direction, drag the right half of a speed keyframe to the right, or the left half to the left.

    A gray area appears between the halves of the speed keyframe, indicating the length of the speed transition. The rubberband forms a ramp between the two halves, indicating a gradual change in speed occurring between them. A blue curve control appears in the gray area.

  5. (Optional) To change the acceleration or deceleration of any part of the directional change, drag either of the handles on the curve control.

    The change of speed eases in or eases out according to the curvature of the speed ramp.
