Why Are Movies Not in 120 fps?

Direct Answer

Movies are not typically shot in 120 frames per second (fps) because the film industry has standardized on 24 fps as the best balance between motion smoothness and image quality. The human eye can perceive more frames per second, but not to the extent that would justify the increased cost and complexity of shooting at a higher frame rate.

Why 24 fps became the standard

In the early days of cinema, filmmakers experimented with different frame rates to achieve the smoothest motion possible. They found that 16 fps was too low, while 32 fps was too high, and 24 fps struck the perfect balance. 24 fps is the minimum frame rate required to create the illusion of continuous motion. Additionally, 24 fps was also a compromise between the technical limitations of film and the creative needs of storytellers.

Why not 120 fps?

So, why not use 120 fps, you might ask? There are several reasons:

• Cost: Shooting at a higher frame rate requires more film stock, more complex camera equipment, and longer shooting days. This increased cost would be passed down to the consumer, making movies more expensive to produce and distribute.
• Artistic intent: Movies are meant to be artistic, not purely technical. Shooting at a higher frame rate could make the film feel too smooth, too video-like, and less engaging.
• Technical limitations: Older film cameras could not handle the increased motion blur required for higher frame rates. Even modern cameras would need significant upgrades to handle the increased data load.
• Human eye limitations: While the human eye can perceive more frames per second, it is not capable of processing the sheer volume of data required to capture and display 120 fps.

Why 60 fps is not enough for movies

Some might argue that 60 fps would be sufficient for movies, considering the advancements in technology and the increased demands for higher frame rates in other mediums like video games. However, there are several reasons why 60 fps is not enough for movies:

• Motion blur: 60 fps is not enough to create the soft, natural motion blur required for cinematic visuals.
• Audio-syncing issues: Higher frame rates require tighter audio-syncing, which can be challenging to achieve, especially in complex productions.
• Color depth and brightness: Higher frame rates require more data, which can lead to increased color depth and brightness artifacts.

Conclusion

In conclusion, while higher frame rates like 120 fps can provide a more realistic representation of motion, they come with significant technical and creative challenges. The film industry has standardized on 24 fps as the best balance between motion smoothness and image quality. While it may not be the perfect solution, 24 fps has been the industry standard for over a century and will likely remain so in the foreseeable future.
