Effects and transitions

Last updated 11/6/2011

3 In the Effect Controls time ruler, position the pointer over the transition, placing it on the thin vertical line that

marks the cut. The pointer changes from the Slide Transition icon

to the Ripple Edit icon .

4 Drag the cut as desired. (You can’t move the cut beyond either end of the clip.)

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” on page 320.)

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.

Reposition the center of a transition

Some transitions, such as Iris Round, are positioned around a center. When a transition has a center that can be

repositioned, you can drag a small circle in the A preview area in the Effects Control panel.

1 Click the transition in a Timeline panel to open the Effect Controls panel.

2 In the A preview area in the Effect Controls panel, drag the small circle to reposition the transition center. (Not all

transitions have an adjustable center point.)
