Motion pictures, TV broadcasts, streaming video content, and even smartphones use the standard frame rate of 24fps. This speed accounts for a phenomenon called motion blur, an optical effect that makes moving objects look out of focus due to quick movement.
Movies are shot at 24 frames per second because of the aesthetic effect that our brain creates when watching them. Which is better between 30FPS and 60FPS at 1080p in videos? Here is a very good gif for comparison. As you can see the higher the fps the smoother and better it looks.
60 fps is another television standard frame rate mostly seen in commercials on television these days. Most movies are now produced at 60 frames per second, giving more smoothness over 30 frames per second.
Universally, 24fps is accepted as the norm for a “cinematic” frame rate. 30fps is accepted for broadcast in North America, and 25fps is the broadcast standard in Europe. In the one-second sequence below, several individual frames pass each second.
I think it was partly because 30 FPS is closer to 25 FPS which is what our brains perceive as cinematic when watching film. I decided to cap my framerate at 25 just to keep things consistent and lo and behold, my experience playing became far more immersive.
60 FPS has some extra detailing in the video quality which restrains the cinematic look. 24 fps was adopted as the format previously when movies were shot on film cameras and moving from 24 FPS to 60fps was an expensive affair.
Netflix offers limited high frame rate content (50fps or 60fps), but the majority of our catalog and viewing hours can be attributed to members watching 23.97 to 30fps content.
But our eyes can only perceive the visual clues in the environment around us at a certain rate due to how quickly they move. Although experts find it difficult to agree on a precise number, the general consensus is that the human eye FPS for most individuals is between 30 and 60 frames per second.
So, if a video is captured and played back at 24fps, that means each second of the video shows 24 distinct still images. The speed at which they're shown tricks your brain into perceiving smooth motion.
This is mind-boggling when you consider that most Disney movies are made at 24 frames per second—that's 24 individual drawings for each second of footage.
To ensure support for the higher frame rates, the HDMI connection with your TV and any other devices like an audio/video receiver (AVR) or soundbar must be configured to use HDMI 2.0 mode or later. This newer standard enables 4K playback at 60fps with HDR color such as HDR10 and Dolby Vision™ as well.
You can choose the frame rate according to your project's specific requirements. 4K 30fps works best for standard video content and offers high resolution and a cinematic look. On the other hand, 4K at 60fps provides smoother motion and is ideal for faster movements.
HOWEVER, we do SEE the world around us in frames. 30–60 fps to be exact. Some experts will tell you that the human eye can see between 30 and 60 frames per second. Some maintain that it's not really possible for the human eye to perceive more than 60 frames per second.
Why do movies look normal and smooth at 30 fps, but games feel bad below 60fps? There are two main reasons: Live action footage has real motion blur. This obfuscates the low framerates and provides the illusion of smoothness.
Now, the researchers have more than doubled it again, to a mind-boggling 156.3 trillion frames per second. The new camera system is called “swept-coded aperture real-time femtophotography” (SCARF), which can capture events that happen too fast for even the previous versions of the tech to see.
To some animals, the tv and movies we enjoy looks more like a flickering slideshow than real movement. Dogs require about 70 fps, and cats require closer to 100 fps. (Cats see a bit more color than dogs do though, so they seem to enjoy watching tv even more!)
More than the image, what grabs their attention is the activity, colour and movement, though not all animals will enjoy watching a screen. Images must be displayed at a frame rate of roughly 15-20 frames per second (fps) for humans to perceive fluid motion. For dogs, it is around 70 fps; for a cat, 100 fps.
Motion pictures, TV broadcasts, streaming video content, and even smartphones use the standard frame rate of 24fps. This speed accounts for a phenomenon called motion blur, an optical effect that makes moving objects look out of focus due to quick movement.
Hollywood movies are commonly filmed at 24fps, movies and videos produced in Europe are often shot at 25fps, and TV shows are filmed at 30fps or 60fps in the United States, and 25fps or 50fps in Europe. These various display rates are specific to each type of content and are known as the native format.
Thats because most people watch YouTube on a device that doesn't support fps higher than 60 (phones, TV's, standard laptops/monitors). Framerates higher than 60fps will probably eventually exist on YouTube, but not anytime soon.
"All six films will include Dolby Vision and HDR10 High Dynamic Range. Each will also include Dolby Atmos audio. (Note that The Hobbit films will NOT include HFR high frame rate—they were shot in 48 fps, but 4K UHD supports 60 fps.)"
