For effectively browsing and navigation, the semantic annotation is essential for the visual content of movies. It is very important to show the particular object that the movie producer wants to highlight in educational videos or commercials. We propose an interactive and structure-based video annotation system, in which we can describe the video object and make multistory movies. The system provides a manual object-based interface for film producers to select the meaningful object and annotate it. We also provide a video story constructing function to interact with the audience.
