Harry Potter's cousin G.Potter has started to go to practica! Some times it goes well and he with partner are disappearing to the other worlds. När difficulties accumulates the whole world is shaking!
But notice! they both have their broom ready for fast escape!
The most interesting thing with this kind of video effect is the fact that the camera holder will be part of the video. Here the lady got upset before you can hear G. Potter start to explain, her camera hand is shaking and the whole room shakes. In ordinary film you don't see it.
(He explained nicely but was frustrated!)
