A talk through two projects that BBC R&D is involved in that use cloud computing for processing media. The first is a case study showing how we used cloud computing to efficiently process a very large archive of media and generate metadata, and the second part is about how this led to us to think about abstracting a service out of it, leading to a general purpose cloud service for analysing media.
