Web-based video editing system for sharing clips collected from multi-users

Movies edited by amateurs are likely to be a sequence of monotonous scenes, where people record video from a single direction, and use video from a single camcorder when editing video. We developed VideoBlocks, a Web-based video editing system. In our system, video clips are collected from multi-users´ camcorders via the Internet and shared among the users. The system allows users to easily use other users´ video clips, each of which is spontaneously videotaped using different digital video camcorders. VideoBlocks provides the capability to extract the date and time information of the video-recording from the digital video cameras, and automatically synchronize them. Through evaluations of the system, we determined the effectiveness of the system.
