4-5 Timeline The timeline provides you with a graphic representation of exactly where each media clip appears in the media stream. Thumbnails corresponding to sound media can be dragged to the timeline and then moved to play automatically at specified points in the linear sequence of streaming media. Decrease Increment button Expands the scale of the timeline (decreases the number of measured increments on the clip ruler), thereby facilitating detailed editing of the media stream. Increment display Indicates the length of time that elapses between each line on the clip ruler. Increase Increment button Shrinks the scale of the timeline (increases the number of measured increments on the clip ruler), thereby facilitating rough editing of the media stream. Clip ruler Indicates the exact starting and stopping points of visual media clips arranged on the Storyboard. Soundtrack Dragging & dropping sound file thumbnails from the thumbnail list window adds them to the movie soundtrack. Once added, sound clips can be dragged to the desired position within the media stream. Placing your mouse pointer at either end of a sound clip makes it possible to trim the play duration of the sound and double-clicking the sound clip opens the sound editor, whereby you can also Trim the sound and control other aspects related to this particular sound.
