Synchronization Method for Improving Temporal Harmony of Music and Video Clips

This paper focuses on temporal harmony of music and video clips. The method for producing a synchronized audiovisual material is proposed. Change points of the direction of the moving object are decided as synchronization points of video clips. The moving area of an object is extracted in order to detect the change points. Only the motion vectors in the area are used. The start point that an object begins to move is considered. Beats are used as synchronization points of a music clip. Playback speed of a video clip is changed to meet synchronization points of music and video clips. The proposed method is experimentally evaluated. Evaluation results show that the proposed method is effective in improving of harmony in specific media data. It is also shown that the start point synchronization influences temporal harmony and general harmony.
