If you have some advanced effects, say with a mask overlaid onto one portion of a scene to have a graphic or replacement video show there, and you want to apply an advanced effect you can bundle all of the different elements into a compound clip to then work with. Each scene can be its own compound clip so if you do need to cut or edit particular scenes you can head directly there and see a much more easy to maneuver timeline of just the elements of that particular scene. If you have a graphic and make it a compound clip you can apply all your regular effects, such as speed ramping, to the graphic and get exactly what you need out of it.
