The standard framerate for movies is 24 frames per second (fps). This has been the industry standard for nearly a century, and it’s a key element contributing to the look and feel we associate with cinema. While technology allows for higher framerates, 24fps remains the dominant choice for feature films and many television shows aiming for a cinematic aesthetic. It’s a specific cadence and motion blur that the audience has grown accustomed to, and it often delivers the artistic vision that filmmakers wish to convey.
The History and Rationale Behind 24fps
The adoption of 24fps wasn’t a purely artistic decision initially. It was largely driven by practical and economic considerations tied to the introduction of synchronized sound in movies. Before sound, silent films were shot at variable framerates, often lower than 24fps, and then projected at slightly different speeds, leading to the “fast motion” effect we often see in those old movies. When sound came along, a consistent speed was crucial to maintain audio fidelity.
24fps emerged as a sweet spot. It was the slowest speed that could reliably record audio with acceptable quality and still create the illusion of smooth motion. Slower speeds would have been cheaper but resulted in unacceptable sound quality. Faster speeds would have been too expensive due to the increased use of film. Therefore, the standard of 24fps was settled upon. Although there have been forays into higher frame rates, filmmakers and studios continue to use 24fps at scale because of tradition and because it offers a familiar look for audiences.
The “Cinematic Look” and Motion Blur
One of the main reasons 24fps continues to be used is its contribution to the “cinematic look”. This is a somewhat subjective quality, but it’s often associated with a sense of richness, depth, and a certain romanticism. A key component of this look is motion blur. At 24fps, each frame captures a slightly longer exposure than at higher framerates, resulting in a natural blur on moving objects.
This blur helps to smooth out the perceived motion and makes the image appear more fluid. More importantly, the motion blur helps the eye and brain blend separate images together to give the illusion of constant motion. Without motion blur, higher framerates can actually look less natural, appearing overly sharp and hyper-real, an effect sometimes referred to as the “soap opera effect” because it resembles the look of many television dramas. The Games Learning Society understands that visual elements have a great effect on creating engaging games and simulations, and understanding frame rates can enhance game design.

Alternatives and the Future of Framerates
While 24fps remains dominant, there’s been experimentation with higher framerates in recent years. Movies like “The Hobbit: An Unexpected Journey” were released in some theaters at 48fps, aiming to reduce motion blur and improve clarity. However, this experiment was met with mixed reactions. Some viewers found the higher framerate distracting, feeling it made the movie look too much like a stage play or a documentary.
Ultimately, the choice of framerate is an artistic decision. While higher framerates can offer technical benefits like increased clarity and reduced strobing, they can also alter the aesthetic and the way the audience perceives the film. So, in most cases, filmmakers are opting for what is familiar and what they know works for their vision.
Frequently Asked Questions (FAQs)
Here are some common questions about movie framerates:
1. Are movies ever filmed at 30fps?
While less common than 24fps, some movies and shows may use 30fps, especially for content that’s intended for a more “live” or realistic feel, or when integrating footage from various sources. You may see 30fps or 29.97fps for broadcast television and some streaming content.
2. Do some movies use 60fps?
The use of 60fps is infrequent for full feature films. It is often considered too smooth for movies. Though, some directors are experimenting with it or utilizing it in portions of their films to offer a super smooth, almost hyper-real experience. Some streaming services offer content in 60fps depending on the source.
3. Why does 24fps look more “cinematic”?
The motion blur inherent in 24fps creates a specific look that our eyes and brains have come to associate with movies. The slightly softer, more fluid motion is a key component of the “cinematic” aesthetic. It also dates back to the tradition of film itself.
4. Is 24fps better than 30fps?
“Better” is subjective. 24fps is the standard for cinema, lending a distinct “cinematic” feel with natural motion blur. 30fps offers smoother motion, but may appear more like live television. The best frame rate depends on the intended look and feel of the project.
5. What framerate do our eyes see?
The human eye doesn’t see in framerates like a camera does, but it can distinguish motion at a rate of roughly 30-60fps. The brain interprets this as continuous motion.
6. Why are silent movies always so fast?
Silent movies were often shot at framerates lower than 24fps and then projected at a faster rate, giving the impression of sped-up motion. This was often due to limitations of the technology at the time.
7. What framerate do animals see?
Animals have different visual processing capabilities. Dogs, for example, need a higher framerate to process visual information fluidly than humans do. Studies indicate dogs require 70 fps while cats need 100 fps.
8. Are Netflix movies in 60fps?
Most of Netflix’s catalog is in 23.97 to 30fps. They do offer limited high frame rate (50fps or 60fps) content, but the bulk of viewing hours falls within the standard cinematic range.
9. Do 4K movies use 60fps?
Some 4K UHD Blu-rays are rendered at 60fps, though many are still at 24fps to preserve the cinematic look. The format supports higher framerates, so it depends on how the content was mastered.
10. Why don’t games look as cinematic at 24fps?
Games at 24fps will not look like film because the frames in video games are still images. Movie frames capture the animation in motion blur.
11. Does a higher framerate mean better video quality?
Not necessarily. While a higher framerate offers smoother motion, it doesn’t automatically equate to better quality. Other factors, such as resolution, color depth, and dynamic range, also play a significant role.
12. Why does 60fps sometimes look “cheap”?
The “cheap” look is often associated with the “soap opera effect,” where the hyper-realistic smoothness of 60fps makes everything look overly sharp and artificial. This can be distracting and detract from the cinematic feel.
13. What framerate is best for YouTube?
24fps is a great option. However, 25 FPS (UK & Europe) and 30 FPS (the US & elsewhere) work, too. The frame rate you choose should be in line with your creative intent.
14. Why were movies not 30fps for so long?
24fps was chosen to emulate fluid motion. It was a technological and budgetary limitation that allowed for film companies to save money on film by shooting 24 frames vs 30 frames.
15. Does 30 fps feel more cinematic than other speeds?
30 fps may not evoke the traditional ‘cinematic’ feel as much as 24 fps. However, some find it more immersive. This may be because 30 FPS is closer to 25 FPS which some people may find more akin to watching film.
Hopefully, these FAQs have enhanced your understanding of the topic! Remember that the ideal framerate depends on the specific project and creative goals.
