近年,デジタルビデオカメラは小型化・軽量化しており,運動会や結婚式の撮影,旅行先での撮影など,きわめて幅広い分野で用いられている.しかしながら,いざ一般の人がビデオ編集をしてみてもなかなか満足できるような映像にならず,単調な映像の連続に感じられることが多い.一般撮影者の作成する映像は,単一角度から撮影した映像がほとんどであり,また,ビデオ編集に使う映像素材も自分自身が撮影した映像のみを用いていることが主たる原因の1 つである.本論文では,同じイベントに参加した複数撮影者の映像をサーバに集めて共有し,インターネット経由で映像編集できるようにするWeb システム「MediaBlocks」を提案する.MediaBlocks を利用すれば,同じイベントを撮影した人たちが映像素材を交換しあうことが容易にできるようになるため,たとえば,自分が撮影できなかったシーンを取り込むことや,プロフェッショナルの映像技法にそった多彩なビデオ編集が可能となる.MediaBlocks は,複数の撮影者が撮影した映像をサーバに集め,自動時間同期処理を施して整理し,Web ブラウザを利用してインターネット経由で映像編集できるようになっている.本論文では,システムの設計,実装,評価,改良について述べる.Recently, the spread of portable digital video cameras enabled us to easily record various family events. Although videotaping and video editing have got quite popular recently, the quality of the produced video has not been improved much. For instance, movies edited by nonprofessionals are likely to be a sequence of monotonous scenes. When editing home movies, users usually use video sources from their own single camcorder. This is one of the significant reasons why nonprofessionals can not create high-quality home movies. We developed MediaBlocks,a web-based video editing system for sharing personal video clips. In the system,video sources are collected from multi-users' camcorders via the Internet, shared among the users, and edited through each user's web browser. The system allows users to use other users' video clips, each of which is spontaneously videotaped by different digital video camcorder, and also enables them to create home movies according to the professionals' important editing rules. The system can extract the date and time information of video-recording from the digital video clips, and synchronize them automatically. Through evaluations of the system, we verified the effectiveness of our system.
