Editing Video Transitions

You can make dramatic changes to a video transition even after you have added it to your sequence. You can adjust its duration and placement and customize its appearance. Opening your transition in the Transition Editor will give you maximum access to the transition's settings, but you can perform many adjustments directly in the Timeline.

Figure 13.20 shows an overview of the Transition Editor interface.

Using the Transition Editor

The Transition Editor (sometimes called the Transition Viewer) is a special version of the Viewer window that you use to make detailed adjustments to transition settings. Use the Transition Editor to do the following:

• Adjust the duration of the transition.

• Reverse the direction of the transition.

• Trim the edit point underlying the transition.

• Adjust the placement of the transition relative to the edit point. You can set a transition to end on the cut, center on the cut, begin on the cut, or occur anywhere in between.

• Adjust the starting and ending effect percentages. The default settings of a simple cross-dissolve would range from 0 to 100 percent. However, in a transition effect that incorporates a motion path, effect percentages specify the portion of the full path that will be included in the transition.

The Timeline's Thumbnail Display option controls the way clips appear in the Transition Editor (Figure 13.21 ). You can adjust the thumbnail display on the Timeline Options tab of the Sequence Settings window.

The change in duration applies equally to both sides of the transition.

Tip

FCE transitions apply equally to both sides of an edit point, so if you need an asymmetrical effectwhere the transition effect is not applied to an equal number of frames on either side of the edit pointyou must build it yourself. Here's how to build an asymmetrical dissolve. Place the incoming and outgoing clips on separate Timeline tracks and allow the areas you want to include in the dissolve to overlap. Then ramp the opacity levels to cross-dissolve from one clip to the other.

• To change the direction of the effect, click the Reverse button.

• To have the transition center on, start on, or end on the edit, click the corresponding placement button at the top center of the Transition Editor. Once you've changed the center point of a transition, these controls won't remember the original edit point.

• Make other settings as desired for the transition. For more information on modifying effects settings, see Chapter 14, "Compositing and Effects Overview."

To preview a transition in the Canvas:

Tip

Hold down the Option key as you scrub the Canvas's Scrubber bar to preview your transition. You can also step through a transition one frame at a time by pressing the Right Arrow key to advance the transition by single frames. Press the Left Arrow key to step backward. A slow-motion view of the transition appears in the Canvas.
