You can arrange selected clips in the Source Area.

To arrange clips in the Source Area:

1. Select some or all clips in the Source Area.
2. In the Source Area menu, select an option from the Clip Arrangement box.

   
   

   Select:	To:
   Stack	Stack the clips one on top of the other. The clips are stacked under the focus clip. There is no indication of how many clips are in the stack.
   Tile	Arrange the clips in a linear tiling pattern with the first clip selected appearing on the bottom left. If space runs out in the Source Area, the tiles overlap.
   Cascade	Arrange the clips in a cascading pattern, which is similar to a stack except that there is a significant offset, so you can see the underlying clips. The focus clip appears at the top of the cascade. If one or all clips are selected, the origin of the cascade is the lower-left corner. Otherwise, the origin of the cascade is the focus clip position.
