Motion smoothing is the process of inflating a film’s framerate by artificially adding frames. Most movies are filmed at a rate of 24 frames per second (fps), while HD TVs often have a refresh rate of around 60 fps. Yet when your TV tries to compensate, it can make the movie look a little too smooth. It can also mean you can see small “artifacts” or visible defects, in the frames. In other words, a setting designed to make your display look better can actually make it look less cinematic.
