Engadget website has just published a round up story on using Kinect devices to create motion capture content.
What they think of iPi Motion Capture:
Another mocap dev that exploits the Kinect 2 is Ipi Soft, which supports multiple sensors. The app, plus a Kinect 2, will never beat a full-blown studio, of course. But if you stay within its limitations and keep square to the depth sensor, you can capture full body performances for games or animated shows. After a bit of cleanup, the results were very usable.
