Hello chilledinsanity,
It really depends on a lot of factors, the way the Kinect camera is positioned, the cloths you are wearing, the floor type.
When positioning the camera make sure it is somewhat level with your chest and that the floor can be seen clearly in green. Spread your feet apart a bit and make sure you are wearing some kind of socks. Also be aware of the specified position to stand away from the camera which can be found at the wiki, I found that floorboards are really bad when it comes to capturing with the Kinect.


Lastly adjusting your dummy actor to the video make sure you positioned it accurately
Hope this helped,
