What is the principle of using photography and recording in movies?

After a certain visual image disappears, the human eye can still keep the image on the retina for about 0. 1-0.4 seconds. When the film rotates at a constant speed of 24 frames per second, a series of still pictures will produce continuous visual impression due to visual persistence, thus producing realistic motion. Film is an important invention in human history, with the help of the knowledge and principles of photographic chemistry, optics, mechanics, electronics and other disciplines.

Precautions:

Post-production should pay attention to creativity. Creative perspective determines the picture quality, which is a point that film and television advertising production companies value. Only the combination of unique perspectives and pictures can be accepted by the public and bring more artistic value to film and television production, reflecting the charm and connotation of film and television works.

Therefore, creativity must be distinguished from what is usually produced, and the breakthrough point of each picture should be grasped, and the whole picture should be cut together logically to make it look smooth and coherent. This is the most basic thing to do.
