english: So let me show you the scene, and then I basically used the trick that was identified by Sergei Eisenstein, which is, if you have a camera that's moving with a moving object, what is not moving appears to be moving, and what is moving appears to be stopped, so what you're actually seeing now is the train is not moving at all, and what is actually moving is the floor.
non_english: Pokazaću vam scenu, tu sam u osnovi koristio trik koji je otkrio Sergej Ajzenštajn, a to je kad imate kameru koja se pomera sa objektom koji se pomera, ono što se ne pomera,  deluje kao da se pomera, a ono što se pomera deluje da je zaustavljeno, tako da ono što u stvari vidite je voz koji se uopšte ne pomera, u stvari pod se pomera.
