Aligning a Transition in the Timeline
You can place a transition so that it starts on, centers on, or ends on the edit point
between two clips in the Timeline. You should choose a transition alignment based on
the editorial effect you want to achieve:
Â Starting on the cut: Choose this alignment if you want the last frame of the outgoing
clip to be fully visible before the transition begins.
Handle of incoming clip

Â Centered on the cut: Choose this alignment if you want the cut point between the
two clips to be the midpoint in the transition.
Â Ending on the cut: Use this alignment if you want the first frame of the incoming clip
to be fully visible.
