Because "Seventh Art" is a synonym for "film art", the term comes from the Italian poet and film pioneer Giotto Canudo. The first few arts are literature, drama, painting, music, dance, and sculpture.

Kanudu believes that among the six arts of architecture, music, painting, sculpture, poetry and dance, architecture and music are the main ones; painting and sculpture are supplements to architecture; and poetry and dance Then melt into the music.

Movies synthesize all these arts into a plastic art in motion. As the seventh art, film is a comprehensive art that includes static art and moving art, time art and space art, plastic art and rhythm art.

Scientific Principles

An important scientific principle on which movies are based is "persistence of vision." Modern science has accurately verified that after vision disappears in front of the eyes, it remains on the retina for about 0.1-0.4 seconds. The standard shooting and projection speed of modern movies is 24 frames per second. Each frame lasts only 1/32 of a second in the human eye. In this way, the motionless picture on the film becomes a moving image after being projected.
