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.
我播给你们看 我就用了Sergei Eisenstein的一招 就是如果你的摄影机也跟着移动物体而移动 那么没移动的物体看起来就像在移动了 而本来就在移动的看起来却像是静止了 所以你们现在所看到的，其实火车是压根儿就没动的 而真正在移动的，则是地板
