i disagree. i think its like a camera at the top spinning around and taking the shots, theyd be a little more seamless that way. like if the vid is 10 fps (it might be my computer but it does seem alittle slow), the camera is spinning 15 reps per second, and taking maybe like 6 photos per rep in different directions. so it takes like 60 photos per second? idk
and as for that cage thing you see around the filmer (move the view to look at his shadow) its prob for stability, like a glide cam type setup thingy.
but if anyone ACTUALLY know how this was done please let me know
