The catch obviously... If you watch it carefully you would notice that he doesn't actually turn his wrist around.. after throwing the apple on the ground, therefore the next catch is actually going back to the beginning of the loop.
It's not really editing still Kitoushi. This is simply a loop. The beginning is catching the apply and then dropping it. Once it is dropped the video ends and enters the endless loop. It's not impressive at all. If you liked it that's okay.
