Who was the first person to make movie special effects by computer?

Movie pioneer Mei Li 'ai is an earlier movie. He first tried a "feature film" of 10 minutes. At the same time, it is also one of the earliest science fiction movies in the world. The special effects techniques he mainly relies on today are basic photography techniques, such as stop shooting, overprint and double exposure. For example, when a shot is being shot, he stops the camera, tells the actor to go away, puts on a burst of smoke, and then turns on the machine to connect the films before and after the stop for development, causing the special effect of people suddenly disappearing. This technology is not surprising now, but it is ingenious, time-consuming and laborious. Although the film is very short, it took the crew more than four months to shoot, which can be seen.

Movie Name: Journey to the Moon (1902)
