I filmed this pupil of mine, Vassilis Y., with a Kinect and with a regular camera. The Kinect was connected to a PC running Brekel Kinect v0.48. Then imported the BVH file into Blender where a specially prepared Biped armature was waiting (with an armature to match the Brekel import - same bones, same names). Then, in the action editor, I attached the animation action to the Biped armature. Then in Blender I used the video sequence editor to combine the Blender scene with the imported straight video (using an Alpha Over strip). Thanks, Vassilis.
