What is slow motion?

In general, the switching frequency of the film projector and the camera is synchronous, that is, 24 shots are taken every second, and 24 shots are also taken every second during the screening. At this time, the normal speed appears on the screen. If the photographer speeds up the shooting frequency, for example, 48 shots per second, then under the condition of still 24 shots per second, there will be slow motion on the screen, which is commonly known as "slow motion".

If the photographer increases the shooting rate, for example, 48 frames per second, the rate will still be 24 frames per second when showing the movie, and there will be slow motion on the screen. This is often called "slow motion". When the shooting frequency slows down to less than 24 frames per second, the screen will move quickly during projection, which is called "snapshot".

Extended data:

In the movie Terminator, the first slow-motion scene is the cool Schwarzenegger getting out of the elevator with a gun in his hand. The camera pointed at him, highlighting his ruthlessness. The second slow motion shows Sarah's reaction to fear (she almost fell and deepened her fear).

The third slow motion brought Schwarzenegger back to an amazing close-up, and he used the first person to close up what Sarah saw, which strengthened his sense of participation.
