In this paper, we discuss methods to extract rhythmic information from movie components and to synchronize these components based on that information. Generally speeking, there are two kinds of rhythm:fixed rhythm and freerhythm. In addition, another type of rhythm that has a certain fluctuation in its frequency can also be introduced in-between. We developed two kinds of synchronization method corresponding to these rhythm types. One is frequency synchronization and the other is counterpoint synchronization. The frequency synchronization is developed for fixed and fluctuation rhythm. It fits the frequencies and the phases of components using the least square method. The counterpoint synchronization is developed for free rhythm. It fits temporal key points of the components as much as possible. We conducted a synchronization recognition assessment test to evaluate these synchronization methods. The result shows that the difference between these method suits the difference of the rhythmic features.
