> Editing Your Project on the Timeline
> The timeline (Figure 25) is a temporal representation of your project. The timeline displays all of the clips in your project and represents the start and end time for each of the clips. You can use the timeline to arrange clips in the order you want them played. You can also layer them, and crop them. You can also use the timeline to add actions (such as fade) to your clips.
> Figure 25. The Timeline Displays Media Clips
> The timeline is divided vertically into tracks to allow you to arrange clips that overlap at certain points on the timeline.
