Thanks to Vern on the heads up on this. It is a free kinematic analysis tool. This could be very useful. The only problem is, the way I understand, you would first need to build a calibration structure. And, that structure would need to be placed where you plan to do the filming. So, it would be best for those who have a dedicated area put aside for this purpose. What do you think of the idea of building a portable one that you could take apart and put back together? Would it be worth the effort? Otherwise, I wouldn't even have the room to store something like that. Oh, one annoying thing. You have to convert your video into .avi before you can download it. Weird but do-able.

Very interesting...finishing corrections on my PhD which part of it was using an active based marker system for motion capture. Give me a few days I'll let ya know. I imagine the boys over at Dartfish would not be too happy about this...
Had a look at it...Seems a little tedious putting in the coordinates and of course building the calibration contraption. I guess the question is what exactly is it going to provide that your 2 eyes do not? Yes, quantitative information may be helpful, however, your eyes will pick up a female with femoral and tibial displacement that may be detrimental to the knee as well as this system. Clinically I think there are simpler methods to observe motion. I know of another free software package called Kinovea.

Thanks for the input Brian- I will check out that website.
