Change transition duration



You can edit a transition’s duration in either a Timeline panel or the Effect Controls panel. The default duration for transitions is initially set to 1 second.

Lengthening a transition’s duration requires that one or both clips have enough trimmed frames to accommodate a longer transition. (See Clip handles and transitions.)

Change transition duration in a Timeline panel

 In a Timeline panel, position the pointer over the end of the transition until the Trim‑In icon  or the Trim‑Out icon  appears; then drag.

Change transition duration in the Effect Controls panel

  1. Double‑click the transition in a Timeline panel to open the Effect Controls panel.
  2. Do one of the following:

    • In the Effect Controls time ruler, position the pointer over the transition until the Trim‑In icon  or the Trim‑Out icon  appears; then drag. (If the Effect Controls time ruler is not visible, click the Show/Hide Timeline View button  in the Effect Controls panel. If necessary, widen the panel to make this button visible and active.)

    • Drag the Duration value, or select it and type a new value. How the transition changes length depends on the alignment option currently selected:

    Center At Cut or Custom Start
    The transition’s start and end points move equally in opposite directions.

    Start At Cut
    Only the end of the transition moves.

    End At Cut
    Only the beginning of the transition moves.

Set the default duration for transitions

If you change the default, the new setting has no affect on transitions already placed.

  1. Choose Edit > Preferences > General.
  2. Change the value for the Video Transition Default Duration or Audio Transition Default Duration; then click OK.
