MAD (Movie Authoring and Design) is a novel design
and authoring system that facilitates the process of
creating dynamic visual presentations such as motion
pictures and lecture-demonstrations.MAD supports
the process by enhancing the author's ability to
structure and modify a presentation and to visualize the
ultimate result.It does this by allowing both top-down
design and bottom-up creation with a hierarchical
multimedia document representation; by supporting the
flexible inclusion and combination of words,images,
sounds,and video sequences; and by providing realtime
playback of the best approximation to the ultimate
presentation that can be produced at any stage of the
design process
