Chapter 35 Adding Transitions 519
VII
Changing the Alignment of a Transition in the Timeline
Transitions can either start on, center on, or end on an edit point. This alignment can
be changed at any time. Changing the alignment of a transition allows you to precisely
control which frames are fully visible when a transition begins or ends.
To change the alignment of a transition in a sequence, do one of the following:
m In the Timeline, select the transition, choose Sequence > Transition Alignment, then
choose another alignment from the submenu.
m Control-click a transition, then choose another alignment from the shortcut menu.
m Select a transition, then do one of the following:
 To start the transition at the edit point: Press Option-1.
 To center the transition on the edit point: Press Option-2.
 To end the transition at the edit point: Press Option-3.
The transition moves to the new alignment position.
Changing an Edit Point After Adding a Transition
Even with transitions applied, you can still trim one or both sides of the edit point (for
example, using the Ripple, Roll, Slip, or Slide tool). Both the alignment and duration of
the transition remain the same. For more information on these types of edits, see
Chapter 32, “Performing Slip, Slide, Ripple, and Roll Edits,” on page 453.
Note: The transition itself limits how far you can trim clips on either side of the edit
point, because the transition requires a certain amount of media on one or both sides
of the edit point.
