Hi, just wondering if anyone here has tried using Kinect for motion capture. I was thinking of using it for film or game animations, but I've heard mixed opinions about it. Does anybody know if it's worth it or how difficult it is to clean up the raw data?

Cleaning up mo cap is a full time job. I haven't tried with kinnect, but I imagine that if you recorded with it, it would basically draw every frame as a key frame, giving you a massive animation file.

Let me know if it works out for you though!

Thanks for the reply. I recently purchased a Kinect for half the retail price. So far, I've only tried using it with Miku Miku Dance. I intend to try it with Brekel's Kinect motion capture for MotionBuilder later. Just trying to decide what to make.

The motions you can record are somewhat limited, but I think the results are still useful. It does record every frame as a keyframe, but there are tools for filtering the motion data. Cleaning the keyframes up in MMD doesn't seem to take too much time, either. I think I'm able to get pretty decent results fairly quickly.

Update: The capture software makes a huge difference. I haven't tried MotionBuilder yet, but I'm currently using MikuMikuCapture and it has many great features to optimise the capturing. The initial results are vastly superior to when I tried using MMD with both OpenNi and Microsoft's SDK with motion filtering tools.

Ipisoft's motion capture software added dual Kinect support not too long ago. Looks pretty decent. I recall reading somewhere (probably brekel.com) that Ipisoft doesn't use the Kinect SDK skeleton, but instead uses a shape-fitting algorithm.

The developer of MikuMikuCapture is currently looking into exporting motion data to BVH format, so that's something to look forward to.

On a related note (but old news), Maya 2012 has some great tools for retargeting animations.

Edit: Update on the PC version of Kinect. Figures it'll be $100 more expensive. http://www.neogaf.com/forum/showthread.php?t=458370
