406 Part III Fine-Tuning Your Edit
Doing a Roll Edit to Change the Location of a Transition
If you move the pointer over the middle of a transition in the Transition Editor, it
changes to the Roll tool. You can then move the edit point along with the transition to
the left or to the right, as long as there is available overlap between the outgoing and
incoming clips.
To do a roll edit, changing the location of a transition:
1 Open the transition in the Transition Editor.
2 Place the pointer anywhere on the transition.
3 When the pointer changes to the Roll tool, drag the edit point and the transition to the
new location.
Using the Roll tool, drag the
edit point to a new position.
Check the two-up display in the
Canvas to help you determine
where to place the transition.
