The cue information that the user joins or the scene message left by the film (such as a snapshot of a digital camera). In addition, the scene message may be a beat tracking rhythm or a tempo accompanying changes in image content or scene, and individual tempos or beats may be treated as a separate scene message. The point in time when these scene information is added can be used as a special effect reservation point. In addition, the content in a video clip may contain many different scenes, most of which are images that are consecutively similar to the background or foreground. In the scene transition, the adjacent scenes often have a large difference from the previous one or several frames or the background or foreground between one or several subsequent frames. Therefore, some of these are in each view. The time point of the clip in the clip where the % scene transition is located can be found by the scene scan method and used as a special effect reservation point.
