Working in the A/B Editing workspace

When you are working in the A/B Editing workspace or the Timeline is in A/B Editing mode, the Timeline uses three separate Video 1 tracks: Video 1A, Transition, and Video 1B. With this layout. you can visually determine the position and duration of a transition between two overlapping clips. For information on A/B Editing mode, see Customizing track views.

To add a transition to the Video 1 track in the A/B Editing workspace:

1 Position one clip in the Video 1A track and another clip in the Video 1B track so that some (or all) of the two clips overlap. The amount of overlap determines the default size of the transition.

2 If the Transitions palette is not visible, choose Window > Show Transitions.

3 Select and drag a transition from the Transitions palette to the Transition track in the Timeline window, between the overlapping area of the two clips. The duration of the transition is automatically adjusted to the overlapping area.

4 To lengthen or shorten the transition, make sure that the pointer tool is selected and press Control (Windows) or Command (Mac OS) as you drag the left or right edge of the transition. To reposition the transition between the clips, drag the transition itself.

Note: Once a transition is added, moving an edge of the transition can cause an edge of the affected clips to move correspondingly, and vice versa. To move a clip or transition edge independently, hold down Control (Windows) or Command (Mac OS) as you drag the edge.

5 Adjust transition settings, as described in Changing transition settings.

6 To preview the transition, see Previewing transitions.
