Using the Tween Media Handler

You can use the tween media handler to send tween values from a tween track to a receiving track, such as a video track or a sound track. To send tween values, you must create a tween track. The Movie Toolbox routes the data from the tween track to the receiving track based upon the receiving track's input map, as shown in Figure 1 .
