Special Effects From Hollywood
Typical special effects include motion blur during wild car races or out-of-focus backgrounds when the camera is fixed on a person in the foreground. Many of these attempt to trick the eye, which has trouble keeping up with the quick movements. The effects are not necessarily realistic, though—even driving at 150 mph on the highway, cars don’t just zoom past looking like a blur of light.
The digital preparation means that you see fewer and fewer differences between PC games and movies, because Hollywood deliberately uses blurring or post-processes fast movements with distortion. As many effects like monsters, crashes or explosions are made as computer animations anyway, the threshold for optical preparation is getting smaller and smaller.
