ABSTRACT
We describe an interface prototype, the Hierarchical Video Magnifier, which allows users to work with a video source at fine-levels of detail while maintaining an awareness of temporal context. The technique allows the user to recursively magnify the temporal resolution of a video source while preserving the levels of magnification in a spatial hierarchy. We discuss how the ability to inspect and manipulate hierarchical views of temporal magnification affords a powerful tool for navigating, analyzing and editing video streams.
