Why Does 60fps Look Weird? The Science Behind Smoothness and the “Soap Opera Effect”
The simple answer is that 60fps (frames per second) often looks “weird” because it reduces motion blur to a level that our brains don’t typically associate with filmed or televised content. We’re accustomed to the specific visual characteristics of lower frame rates, particularly the motion blur inherent in 24fps (cinematic) and 30fps (television) standards. This alteration in visual cues triggers a perceptual dissonance, leading to the frequently cited “soap opera effect,” or a sense of “cheapness” or “fakery.” The increased clarity and sharpness of motion can feel unnatural, particularly when applied to narrative content.
Deconstructing the “Weirdness” of 60fps
To truly understand why 60fps elicits this reaction, we need to delve deeper into several key aspects:
1. The Role of Motion Blur
Motion blur is a critical visual element created when a camera captures moving objects. At lower frame rates, like 24fps, each frame captures a slightly longer exposure time, resulting in a blurring of fast-moving elements. This blur, while seemingly a flaw, provides a sense of fluidity and continuity, blending the individual frames together.
60fps, with its shorter exposure times per frame, significantly reduces motion blur. The image becomes sharper, and motion is more defined. While technically “better” in terms of detail capture, this reduction in blur can feel jarring because it doesn’t align with our pre-existing visual expectations for filmed content.
2. The Cinematic Look and 24fps
The 24fps standard, established during the transition to sound film, has become deeply ingrained in our perception of “cinematic” visuals. This frame rate provides a specific amount of motion blur that, over decades, our brains have learned to associate with high-quality filmmaking. The blur smooths out the movement and gives the impression of a more professional appearance. Deviating from this frame rate, especially by significantly increasing it, disrupts this established visual language.
3. Habituation and Perceptual Expectations
Our brains are incredibly adaptable. We become accustomed to specific visual cues and patterns over time. The prevalence of 24fps and 30fps content throughout our lives has created a strong perceptual expectation. When we encounter 60fps, the sharp, hyper-real motion triggers a sense of unease because it clashes with these ingrained expectations. We can see the difference between 30 and 60 fps, but are not used to that extreme clarity.
4. The “Soap Opera Effect”
The term “soap opera effect” perfectly encapsulates the common reaction to 60fps. Soap operas and other low-budget television productions often utilize techniques to enhance the perceived smoothness and clarity of their visuals. This includes shooting at higher frame rates or using digital smoothing filters. As a result, viewers have come to associate this hyper-real look with cheaper, less sophisticated productions.
5. Gaming and 60fps: A Different Story
Interestingly, the “weirdness” of 60fps is less pronounced, and often even preferred, in the context of video games. This is because the higher frame rate translates to increased responsiveness and smoother gameplay. In fast-paced games, the reduced motion blur helps players track moving objects more easily and react more quickly. The need for responsiveness outweighs any perceptual discomfort associated with the reduced blur.

When Does 60fps Work Well?
While 60fps can feel unnatural in certain contexts, it’s not inherently bad. In fact, it can be highly beneficial in specific scenarios:
- Sports Broadcasting: The increased clarity and reduced motion blur allow viewers to track fast-moving action more effectively.
- Documentaries: When capturing real-world events, the enhanced detail of 60fps can provide a more immersive and engaging viewing experience.
- Slow-Motion Footage: 60fps footage can be slowed down significantly without introducing excessive blurring or artifacts.
- Archival Footage: Digitizing old film and video at a high frame rate helps to preserve the quality of the original content.
Adapting to Higher Frame Rates
As technology advances and higher frame rates become more common, our perceptual expectations may shift. Future generations, exposed to 60fps and even higher frame rates from a young age, may not experience the same “weirdness” that current viewers do. Ultimately, the perceived quality of a frame rate is subjective and heavily influenced by personal preferences and pre-existing visual habits.
Frequently Asked Questions (FAQs)
1. Why does 60fps video look sped up?
It doesn’t actually look sped up. It just seems faster. Our brains are accustomed to the slight micro-jitters and motion blur found in lower frame rate videos. The fluidity of 60fps can be misinterpreted as fast-forwarding due to the removal of these familiar visual cues.
2. Why does 60fps look so smooth?
There are two main reasons. Firstly, live-action footage typically has a good amount of real motion blur. 60fps can capture this real blur and provides the illusion of smoothness. Secondly, it simply has more frames per second, capturing a higher density of information, thus smoothing out the transitions between frames.
3. Why does 60fps look better than 30fps?
Objectively, 60fps captures more detail and handles motion better than 30fps. If a scene has a lot of movement, 30fps can look blurry and indistinct. 60fps results in smoother footage in these instances.
4. Why does 24fps look cinematic?
24fps has a distinct rhythm of motion, and the right amount of blur, making it more aesthetically pleasing. This is the standard from older forms of film which is why we perceive this to be of higher quality.
5. Is 30fps to 60fps noticeable?
Yes, 60fps is demonstrably smoother than 30fps. Some people may not consciously perceive the difference, but it exists. For gamers, a faster frame rate is more ideal, especially when the game has fast movement and a lot of action.
6. Why does high fps look choppy?
Higher fps than your monitor’s refresh rate can lead to screen tearing, which creates a choppy appearance. G-Sync or FreeSync technologies can help mitigate this issue, but exceeding your monitor’s capabilities unnecessarily can generate heat and strain your system.
7. Why does 60fps look cheap?
This perception stems from the association of higher frame rates with low-budget television productions and the “soap opera effect.” We are simply used to seeing feature films at a much lower frame rate.
8. Why do streamers games look so smooth?
Streamers typically prioritize both resolution and frame rate. A high frame rate (60fps or higher) ensures a smooth and responsive image, while a high resolution provides a sharp and detailed picture for viewers.
9. How much FPS can the human eye see?
There’s no definitive answer. Experts generally agree that most people can distinguish differences up to around 60fps, though some individuals may perceive even higher frame rates.
10. Does 120Hz make 60fps look better?
A 120Hz monitor can potentially improve the viewing experience of 60fps content by ensuring smoother frame pacing and reducing the risk of screen tearing. However, the actual difference may be subtle.
11. Why does high frame rate look fake?
It looks fake because it deviates from our established visual expectations for film and television. The reduced motion blur and increased clarity can create a hyper-real appearance that we don’t typically associate with narrative content.
12. Is anything above 60 fps noticeable?
Yes, many people can perceive differences in smoothness beyond 60fps, especially in fast-paced games where responsiveness is critical.
13. Why does 24fps look better?
“Better” is subjective. 24fps produces more motion blur, which has become the standard for cinematic visuals.
14. Why 24fps better than 30fps?
Neither is inherently “better.” 24fps offers a classic cinematic aesthetic, while 30fps provides a slightly crisper and cleaner image often preferred for television. It all depends on the situation.
15. How long is 1 frame in 60fps?
Each frame in a 60fps video lasts approximately 16.67 milliseconds (1/60th of a second).
