Real-time Visualisation and Browsing of a Distributed Video Database

摘要

We present the initial results of a system designed to visualise and browse a distributed database of high definition video. Multiple video clips are taken from the database and streamed as textures within a 3D environment. The rotation, movement, and zoom that this allows enables the clips to be organised, previewed, and selected for further editing. The power of the system lies in the ability to stream multiple clips in real time (including multiple versions of the same clip) and organize the clips according to simple metadata. This latter ability allows a typical user, such as a production director or editor, to rapidly discover relevant or related clips and preview the application of several different post-production filters in real-time, increasing the usability and speed of a typical production workflow.
