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. The Competence Centre for Non-Textual Materials at the German National Library of Science and Technology (TIB) started developing the portal in cooperation with the Hasso Plattner Institute for Software Systems Engineering, in July 2011. The TIB AV-Portal went online in spring 2014.
