Despite the multiplicity of data types and rich linking and nesting available in general multimedia systems, most digital video systems have represented video only as linear sequences of frames and shots. We extend previous work that proposed representing digital video as hierarchically structured documents composed of modular building blocks including outlines, scripts, audio sequences, still images, titles, and motion sequences. We review how such a representation can aid video authoring. We then show how such structure can aid video editing, localizing, browsing, updating, publishing, navigating, and searching. Applications are illustrated with examples from real projects.
