High score (promotion question) Why does the camera drive the film to rotate faster and produce slow motion?

Because the speed of shooting is directly proportional to the speed of playback, and after speeding up the number of freeze frames, the length of the film will change for the same action, and the number of freeze frames on the film will increase. When playing at normal speed during playback, you will feel that the action has become slower.

For example, if the normal speed is set at 24 frames per second, if the shooting is upgraded to 36 frames per second, it means that every frame is 36 frames per second. There are 36 frames of images in a second-second film, but when playing this one-second image, it is still played at 24 frames per second. The same one-second motion is half as slow. That is, the playback time is 1.5 seconds/
