Describe about Transition Effects and Layouts.

- The transition effects may be applied to any visual clip irrespective of the layout.

- The area that is covered during a clip’s play is treated as its background.

- The background can be a region color or clip in another region or a clip in the current region.

- The transition effect introduces the clip over, or removes the clip from its background.

- Hence, all the clips may not be the same size.
