What is the history of the movie determining 24 frames per second?

Excerpts from Baidu know that in the earliest movies, a still image was called a "frame". The picture in the movie is 24 frames per second. Why 24 frames? How did this figure come from? Because the visual persistence of human eyes just meets the standard of 24 frames per second, it is meaningless to use more, which will waste film and increase cost, so it is 24 frames. This 24 frames per second is a common format for film. In other words, if you shoot a film, it will take 24 frames in one second. To put it bluntly, if the camera takes 24 negatives, people's visual persistence is 0.0 1 second, and people will feel unable to move. Because it's for people to see. Too much is useless. Similarly, for dogs, it should be at least 50 frames per second. That's why dogs don't like watching TV as much as cats. Depending on the playback device, the concepts of field and frame rate are easy to handle. There are two display modes for a frame, one is progressive display, and the other is single frame display. If line by line is actually 24 frames, that's 48.
