Present movie production handles all contents as digital files and demands the collaboration of remote locations. This process requires contents transfer among locations and collaboration tools. For more creative collaboration, automatic content analysis that supports editing is very effective. We propose an online collaborative platform based on retrieval technologies for movie production. Our system bases automatic content analysis on retrieval techniques for both video and audio clips. A GUI-based interface connects this function to the online collaborative system, and the total system enables efficient and secure collaboration among remote locations. In particular, our search function yields more precise detection through accurate timing, system scalability, and memory savings.
