You can use the Effect Controls panel to change settings for a transition you placed in a sequence. Settings vary from transition to transition. In the Effect Controls panel, the adjoining clips and transition are displayed in A-roll/B-roll format.
A. Play The Transition button B. Transition preview C. Edge selector D. Clip previews E. Start and End sliders F. Clip A (first clip) G. Transition H. Clip B (second clip) I. Current‑time indicator
- To open the transition in the Effects control panel, click the transition in a Timeline panel.
- To show or hide the time ruler in the Effect Controls panel, click the Show/Hide Timeline View button . If necessary, widen the panel to make this button visible and active.
- To play back the transition in the Effect Controls panel, click the Play The Transition button. This doesn’t affect the Program Monitor.
- To view frames from the actual clip or clips in the Effect Controls panel, select Show Actual Sources.
- To see a specific frame of the transition in the small preview, click the Play The Transition button. Then drag the current-time indicator in the Effect Controls panel’s time ruler to the desired frame.
Keyframes cannot be used with transitions. For transitions, the Timeline View in the Effect Controls panel is used for adjusting transition alignment and duration.
Kevin Monahan shows how to create new transitions based on effects in an article on the Adobe website: using effects as transitions in Adobe Premiere Pro in this blog post.
You can change the alignment of a transition placed between two clips in either a Timeline panel or the Effect Controls panel. A transition need not be centered or strictly aligned to the cut. You can drag the transition to reposition it over the cut as desired.
You can’t change a double-sided transition into a single-sided transition. If you realign a double-sided transition to the start or end of a clip, it will use handles from the adjacent clip.
In the Effect Controls time ruler, position the pointer over the center of the transition until the Slide Transition icon appears; then drag the transition as desired. For finer control, magnify the time ruler.
To center the transition on the cut line, in the Effect Controls panel, double-click the transition, and select Center At Cut.
To place all of the transition in the clip preceding the edit point, drag the transition to the left to align its end to the edit point. Alternatively, in the Effect Controls panel, double-click the transition, and select End At Cut.
To place all of the transition in the clip following the edit point, drag the transition to the right to align its beginning to the edit point. Alternatively, in the Effect Controls panel, double-click the transition, and select Start At Cut.
To place unequal portions of the transition in each clip, drag the transition slightly left or right. For finer control, zoom in on the time ruler.
You can also choose an option from the Alignment menu in the Effect Controls panel. Custom Start appears as an option in the Alignment field only when you drag the transition to a custom location over the cut.
You can adjust the location of the cut in the Effect Controls panel. Moving the cut line changes the In and Out points of the clips, but does not affect the length of the movie. As you move the cut, the transition moves with it.
You can’t move the cut beyond the end of a clip. If both clips do not have trimmed frames extending beyond the cut, you cannot reposition the cut.
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.)
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.
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.
Change the orientation or direction of the transition. Click an Edge selector arrow on the transition’s thumbnail. For example, the Barn Doors transition can be oriented vertically or horizontally. A transition doesn’t have Edge selectors if it has one orientation or if orientation isn’t applicable.
Start and End sliders
Set the percentage of the transition that is complete at the start and end of the transition. Hold down the Shift key to move the start and end sliders together.
Adjusts the width of the optional border on the transition. The default Border is None. Some transitions do not have borders.
Specifies the color of the transition’s border. Double-click the color swatch or use the eyedropper to choose the color.
Plays the transition backward. For example, the Clock Wipe transition plays counterclockwise.
