If you the video looks likely to be already clear to many how it's done: First of 3D tracking, keying and then then added a 3-D space, which took over the camera of tracking data. The cool thing about this clip is that everything completely in the new Blender (ie current Tomato-Branch) has been created, so compositing, keying, and 3D tracking. Without additional software. And who does not want to believe it, the place here equal nor the making of as a time-lapse. We can already expect now wait to see the functions shown in the next official release.
