The formation and significance of slow motion and fast motion in movies.

A: Fast action means shooting all kinds of activities at a speed below 24 frames per second. The target usually moves at normal speed. When the captured shot is displayed at a rate of 24 frames per second, it will lead to faster action. This technique is sometimes used to improve the natural speed of the scene. Early silent comedies were shot before cameras and projectors were standardized to 24 frames per second, so these films were shown at the speed of today's projectors, and the speed became faster. However, even in the case of 16 or 20 frames per second, some early directors used fast action to achieve comic effect. Slow-motion shots are displayed on the screen at a normal speed higher than 24 frames per second. Slow motion often makes sports have the nature of ceremony and solemn significance. Even past activities have become as beautiful as slow-motion dancing. If quickness is often the natural rhythm of comedy, then slow and solemn movements are often associated with tragedy. When violent scenes are filmed in slow motion, the effect is extremely beautiful.
