This paper discusses a class of multimedia displays that we call popout videos. A pop-out video is a composition of multiple elementary displays. Some of these base elements are video streams, and some are three-dimensional graphic displays. The elementary displays of a pop-out video may be related in two ways. They may be contiguous portions of a single virtual world, forming what we call an integrated video space. Alternatively, they may be parts of distinct spaces, forming what we call a complementary video space. In both cases, the elementary displays are related to each other by coordinated event handling. In our on-going research, we are using pop-out videos to create multimedia virtual worlds and to orchestrate the presentation of data in multiple media. After a survey of related work, the paper outlines our initial implementations of pop-out videos and presents future plans.
