Why is the speed of 24 frames per second sufficient for a movie to achieve a smooth visual effect, but it seems bumpy for computer games? The reason is very simple. when the camera is working, it does not take a frame at rest. Each frame it takes already contains all the visual information within 1/24 seconds, including the object displacement. If you press the seek key when watching the video, what we get is not a clear static image, but a blurred image, because of this. The computer cannot do this. Every frame in the game is a static picture. If you capture an image while moving, you will surely get a clear static picture. The purpose of motion blur technology is to enhance the realism of Fast Mobile scenarios. This technology does not insert more displacement information between two frames, this is an effect of mixing the current frame with the previous frame.
