Interactive Video Object Manipulation on Vimeo

This demo illustrates our research to bring interactivity to video editing: Our system analyzes videos using computer vision techniques, enabling interactive annotation, browsing, and even drag-and-drop composition of new still images using video footage.

I honestly can't say what that I am buying this whole convergence of video and stills... Perhaps I am getting old, but a still image has a different thought process then a video. Maybe you will see wholly commercial applications, like bundling still and videos for weddings. But I see both mediums suffering for the other if you straight up combine them into one shoot. I dunno.... I spend a lot of time thinking about this right now.
