When you drag a source
            clip to the timeline, the clip is placed on the track directly beneath
            the cursor. If you drag a clip below the last track on the timeline,
            a new track is created. 
         
         You
            can edit entire clips to the timeline as well as specific frames
            of a clip by setting in and out points on the source clip.
