The browsing mechanism offers a simple but powerful interface for browsing videos at different levels of granularity. All interactions can be carried out with no modal changes at all. The interface is easy to understand and efficient to use. A first evaluation proves the suitability of the presented design for casual users as well as for creative professionals such as video editors.
