I finally found time to do a quick test at work today. My old duo-core laptop is able to capture from the Kinect just fine if I use an external the mini-RAID I built a few years ago for editing HD footage. The RAID is an eSATA device containing two 7200 rpm laptop drives. The interface is a eSATA ExpressCard. Nothing fancy but if anybody wants to know where to get the parts just let me know. That said, in my opinion, it's better to got with a modern SSD. These days an SSD will probably be cheaper now than building a RAID and you'll get better performance too.

When I got home I tried to track the data. Calibration was fully automatic and as far as I knew, it looked good, though maybe not as 'deep' as in the wiki images. I positioned, reshaped, posed the actor, clicked Refit Pose, and the rig appeared to fit in the capture data well. But when I clicked track forward, it tracked for about 3 frames and then the actor got blown away. Yikes! I guess Studio didn't like my acting very much. :)

I suspect my small office space was less than ideal. I was shooting into a corner and the walls were close to my hands. Also, there were shiny black computer cases on the floor which I think confused the depth sensor.

I'll try another test later this evening. I suspect I'll have better luck with a test captured in my living room, where there is a little more space and fewer 'obstacles'.

More later.

I just noticed that I had shot two tests in my office. I loaded the second footage and it seems to be tracking much better. I think the problem with the first footage is the feet were too close to the bottom edge of the video.

Most of it actually tracked surprisingly well. There was one error when one arm became occluded by the other but it may be possible to correct this. I'll try correcting the error after dinner.

Anyway, for having spent so little time with the Kinect beta, this test already looks promising.
