Frame Rates P.1

1. What were three reasons why 24 frames per second chosen as the modern standard frame rate for filmmaking?

24 frames per second was chosen as the modern standard frame rate because it was a number that was easily divisible by six numbers, including 2,3,4,6,8, and 12. Although other numbers have similar aspects of being easily divisible, 24 was chosen because it was the most financially efficient, requiring the least film as possible. Sound was what drove the introduction of the 24 fps second standard, however. Because of this new introduction of audio waves on the side of the film strip, the films had to be in rigid format. In order to achieve the desired 48 projected frames per second, 24 was a convenient number that required 2  blades to run the film.
