Formation of slow-mo and fast-motion in movies and their meanings.
Answer: fast action is the filming of various activities at a rate of less than 24 frames per second. The subject is usually moving at a normal speed. When the filmed footage is shown at 24 frames per second, it creates the effect of faster action. This technique is sometimes used to enhance the natural speed of a scene. Early silent comedies were filmed before cameras and projectors were standardized to a uniform specification of 24 frames per second, so when these films are projected at the speed of today's projectors, they are faster. However, even at 16 or 20 frames per second, some early directors used to utilize fast motion for comedic effect. Slow-motion footage is a summary of various movements shot at a rate higher than 24 frames per second and projected on the screen at normal speed. Slow motion often gives movement a ceremonial and solemn quality. Even the most common activities become as beautiful as a dance in slow motion. If speed is often the natural rhythm of comedy, slow, solemn movement is often associated with tragedy. When violent scenes are shot in slow motion, the effect is perversely beautiful.
