What principle is this film based on?

According to the principle of visual persistence, film is a technology that uses photography and recording to record the images and sounds of external things on film (except digital movies), and forms moving images and sounds that can express certain contents on the screen through projection and restoration technology.

Film history is to study and summarize the artistic phenomenon of film, reveal the historical development law of film as an art, and expound the inheritance and innovation of various styles and genres of film, and how they influence each other. Film criticism is the interpretation and evaluation of movies, usually referring to more in-depth film criticism.

Three elements of the film:

1, picture: including composition, scene, position, angle, lens movement, color, light, etc.

2. Sound: sound (action sound, natural sound, background sound, special sound, etc. ), lines (dialogue, narration and monologue), music (active music, passive music).

3. editing: in addition to organizing video and sound materials into movies, editing can also create a "montage effect" of "1+ 1 > 2".
