Why am I such a sceptic when it comes to Microsoft? What I mean is - as fantastic as this prototype is - I get the distinct impression that the on-screen results we see here are better than the dolly-shot's wobble-and-jerk. Sorry, I just find myself suspecting Microsoft has got involved in the video quality control.

One thing we can all start doing straight away is at least mount a second GH2 and lens on our rig.

Brilliant. I want one!

Years ago they had robotic cameras at the BBC news studio. They had huge barcodes around the floor so the cameras would know where they were, apart from once when one camera "thought" it was in the wrong studio and made a dash for the wall. But aside from that glitch, they worked really well. And of course Sony had those robotic video conferencing cameras which could follow people around the room.

Using a Kinect to do this is very clever idea. It's really interesting to see the work that's gone into the software (1st video).
