Why the speed of the wheel after the speed looks like a backward turn?
Not very understand, but it involves the camera frame number, initiate it. For example, the side of the tire has a large white LOGO, the camera frame number 30 frames, equivalent to 30 photos per second, and when the tire speed caused by the 30 photos of each tire that white LOGO are in the The same position, it looks like the tires are not turning the same.
