Spatio-Temporal Video Warping

Check out the videos on this academic page (link in title).
These investigators are inventing new tools for navigating the 3 dimensional data cube of a video stream, and rearranging it spatio-temporally. You will see a demonstration of several time-warping effects. In one, a panoramic video is created out of a pan of a waterfall. In the panorama, the water falls at the same time, even though the imagery was taken at different times! In another demo, the demolition of a coliseum is shown, and in different versions of the demolition, different parts of the structure give way in different sequences. In yet another, the investigators can choose who wins in a swim meet. Check it out!
