You can access available transitions in the Transitions panel (click Transitions on the Action bar).
Quick view: All the available transitions appear as thumbnails in the Transitions panel. The Quick view contains a subset of the transitions available in the Expert view.
Expert view: The transitions are organized into categories. You can narrow a search for transitions by choosing a transition type, such as Dissolve, from the Category menu. You can also search for a transition by typing its name in the search box. The Expert view has more transitions compared to the Quick view.
Video transitions have animated thumbnail previews that show how they affect clips. Select a transition to set its thumbnail in motion. You can preview an animated thumbnail transition in the Transition panel without having to apply it to a clip.
Adobe Premiere Elements includes two audio transitions in the Crossfade category: Constant Power and Constant Gain. Though both provide fades, they differ slightly. Constant Power creates a smoother-sounding fade, while Constant Gain, though mathematically linear, often sounds abrupt.
The default transition is used in slide shows you create and files you import from Adobe® Photoshop® Elements. It is also used in motion backgrounds you create for DVD menus. The default transitions are Cross Dissolve for video or still images and Constant Power for audio. However, you can change these defaults.
In the Quick view timeline, drop zones (indicated by vertical green lines) appear the moment you drag a transition. The drop zones let you easily apply transitions between clips.
If any one side of the clip has nothing adjacent to it, drag the transition to the transition rectangle on that side of the clip.
If the clip is adjacent to another clip, drag the transition to the desired edge of the clip. In the Transitions contextual control set Alignment as Left Clip, Between Clips, or Right Clip.
When applying transitions to the Expert view timeline, you can choose from alignment options, Left Clip, Between Clips, or Right Clip.
To apply a transition between two clips in the Expert view timeline the clips must be on the same track, with no space between them.
If a double‑sided transition must use repeated frames (rather than trimmed frames), the transition icon contains additional diagonal lines. The lines span the area where it has used the repeated frames.
Drag the transition from the Transitions panel to the cut between two clips in the Expert view timeline, and release the mouse button when one of the following alignment icons appears:
Start At Cut transitionStart At Cut
Aligns the beginning of the transition to the beginning of the second clip.
Pressing Ctrl while dragging a transition lets you select Start At Cut, Center At Cut, or End At Cut by slowly dragging the transition left and right over the cut.
When you create a single‑sided transition, whatever is below the transition in the Expert view timeline appears in the transparent portion of the transition. For example, If you want the clip to transition to black, it must be on Track 1 or have no clips beneath it. If the clip is on a track above another clip, the clip on the lower track appears in the transition, so the transition will appear to be double‑sided.
Do one of the following:
To select non-consecutive clips, Shift-click each clip.
To select consecutive clips, click in the Project Assets panel, and drag a marquee around the selected clips.
To select all the clips, press Ctrl-A.
Right-click/ctrl-click the selected clips, and select Apply Default Transition Along CTI.
Select one of the following options:
To apply default transitions between multiple contiguous clips on the same track:
Ctrl-click the clips to which you want to add the default transition.
Right-click/ctrl-click one of the selected clips.
Select Apply Default Transition.
The transition is applied at the cut between each of the contiguous clips.
You can replace a transition by simply dropping a new transition onto the old one in the Quick view or the Expert view timeline. When you replace a transition, Premiere Elements maintains the alignment and duration of the original transition; however, it discards the settings of the original transition and instead uses the default settings of the new transition.
You can preview transitions you’ve applied from either the Transitions contextual control or the Monitor panel. The Transitions contextual control provides a preview area where you can display thumbnails of the actual clips or the default thumbnails (the letters A and B). Adjust your transitions in the Transitions contextual control and preview the transitions as you make adjustments.
If you have a digital camcorder, you probably can connect it to both your computer and TV to see real‑time previews on the TV monitor. This gives you a better sense of how the transition will look in the finished movie.
In the Quick view timeline or the Expert view timeline, move the current-time indicator to the left of the transition, and then click the Play button in the Monitor panel.
To preview a particular frame of the transition in the Monitor panel, drag the current‑time indicator to the desired frame.
