It lists all source clips in the project. The Source view shows the original video clip and the Program view displays the current state of your edited program. The Timeline window provides a time-based, schematic view of your program, including all video, audio, and superimposed video tracks. It graphically shows the placement of each clip in time, its duration, and its relationship to the other clips in the program. Changes that you make in this window appear in the Program view.
Premiere provides other specialized windows for creating titles, mixing audio, and storyboarding.
Most windows and palettes include specialized menus, and all windows have context menus that adapt their content to the current task. Timeline markers can include a comment, a Web link, or a chapter link. For example, when you embed a link to a URL in your movie, and launch that movie from a Web page, the embedded URL jumps to the specified location. Chapter links, like the chapters of a book, divide a QuickTime or DVD movie into addressable segments. Grab your first clip, and drag it into the Timeline.
