The film or movie is the most popular and common video resource. In this paper we use the film video as an example, aims to implement real-time retrieve of explosion and shot scenes, has carried on the following research mainly: first, we proposed a method of real-time recognition of explosions based on dominate-color and audio information and improved the accuracy the retrieve;second, we proposed a method of real-time retrieve of shots scenes based on audio information and differences between frames when the shot occurs;third,a whole video abstraction system is proposed, it can cut off the clips which have been retrieved and merge them into a independent video abstraction in the same time edit the information of the it ;forth, it offers two-level retrieval structure of"key frame-highlights"and can play segmentation result and the whole video just like a video player.
