It takes a lot of movies to spoof film production.
Most of the films were filmed on 35mm film.
You can get 16 frames (

The movie projector moves the movie at 24 frames per second, so 1 frame is required. 5 feet (45. 7 cm)
Create every second of a movie.
At this speed, you will need a lot of movies soon.
Consider these calculations: you can use this formula to figure out how many movies you need to see the next movie.
Just multiply the minutes in the movie by 90 to get the footage of the movie.
Because the long piece is too long, the distributor divides it into parts that are rolled on the reel. A typical two-
The movie will be divided into five or six volumes in an hour.
In the early days, the film was shown with two projectors.
One projector is connected to the first disc thread, and the other projector is connected to the second disc thread of the movie.
The projector will start shooting on the first projector, and when 11 seconds from the end of the reel, a small circle flashes briefly in the corner of the screen.
This reminds the projector that he is ready to replace another projector.
When leaving for a second, the projector presses the conversion pedal to start the second projector and stops the first projector, another small circle flashes.
When the second reel rolls, the projector removes the first reel on the other projector and threaded the third reel.
The whole film continues this kind of communication.
In the 1960 s, a device called platters began to appear in theaters.
The platter consists of two to four large discs with a diameter of about 4 or 5 feet, stacked vertically, 1 to 2 feet apart.
The payment component on the platter side feeds the movie from one disc to the projector and pulls the movie back from the projector to another disc.
The disc is large enough to accommodate a large reel of the entire film, and the projector is assembled by splicing all the film lengths on different reels together.
Splicing is the process of cutting the end of a film so that it can carefully match to the beginning of the next film and then record the film together.
Once the projector can put all the movies of a movie on one reel, something happens: These two factors make you need less manpower and less projectors, so the cost of watching a movie is lower.
This led to the birth of this diversity, with several halls in a theater.
Since they came out, multiplexing has grown from two or four halls to 15 to 20. These super-
Large theaters are often called large comprehensive theaters.
