Just using a few minutes of video to study vibrations they are then able to manipulate items in the video.

they say “This technique lets us capture the physical behavior of objects, which gives us a way to play with them in virtual space,” says CSAIL PhD student Abe Davis, who will be publishing the work this month for his final dissertation. “By making videos interactive, we can predict how objects will respond to unknown forces and explore new ways to engage with videos.”
This will be highly useful for 3d artists who are not PROFESSIONAL compositors.
