 Fast-forward (greater than 100% speed): Fast-forward speed can be seen as a steeper line,
in which several frames of a video clip play in the space of one frame of the Timeline.
 Freeze frame (0% speed): So far, all these graphs have illustrated forward-playing clips,
represented by a line that slopes upward. A freeze frame, represented by a flat line,
may also be created with the time graph.
 Reverse speed (less than 0% speed, or negative speed): When a clip plays in reverse,
previous frames of the video clip are mapped to successive frames of the Timeline.
Reverse speed is represented by a line that slopes downward.
