I created this video with Enodorphin, dynamic Motion Synthesis software. It uses a combination of captured motion, animation and physics based simulation which you can seamlessly join together and tweak. It's used a lot for game sequences but its also being used in tv and cinema to simulate stunt scenes etc. That Advert where the guy falls down the skyscaper with suckers attached to him was done in Endorphin. It's a bit tricky to get used to at first but good fun. Obviously I haven't done a background or skinned any of the characters though.
