The TIB AV-Portal
"The TIB AV-Portal is a web-based platform for quality-tested scientific videos from the realms of technology/engineering, architecture, chemistry, information technology, mathematics and physics. Amongst other things, the videos portray computer visualisations, learning material, simulations, experiments, interviews, and recordings of lectures and conferences. A key feature of the portal is the use of different automated video analyses. The added value: these video analyses enable pinpoint searches within the video content."
