When recording 4k video with an Apple iPhone, which one is better, 24, 30 or 60fps?

When recording 4K video, what is the difference between 24FPS, 30FPS and 60FPS?

When recording videos on an Apple phone, you can choose between HD and 4K video formats in the upper right corner. There are three switchable numbers at the back: 24, 30, and 60. What are these three numbers? Which one is better for recording videos? This number is Frames per second (Frames per second) or fps for short..

What is FPS/Frames per second?

FPS is a definition in the field of graphics, which refers to the number of frames transmitted per second. Generally speaking, it refers to the number of frames of animation or video. FPS is a measure of the amount of information used to save and display dynamic video. The more frames per second, the smoother the action shown will be. Generally, the minimum to avoid jerky movements is 30. Some computer video formats can only provide 15 frames per second.
FPS can also be understood as what we often call "refresh rate (unit: Hz)", such as the "FPS value" we often say in games. When we install and purchase graphics cards and monitors, we will all pay attention to the "refresh rate". Generally, we set the default refresh rate to be above 75Hz (that is, 75 frames/second). For example: a refresh rate of 75Hz means that the screen only scans 75 times in one second, that is, 75 frames/second. When the refresh rate is too low, we can feel the screen flickering and incoherence with the naked eye, which has a negative impact on the image display effect and visual perception.
Played back at a speed of 24 frames per second, that is, 24 still images are continuously projected on the screen within one second. The unit for animation playback speed is fps, where f is the English word Frame (picture, frame), p is Per (per), and s is Second (second). In Chinese, it means how many frames per second, or how many frames per second. movie is, usually referred to as 24 frames.

What is the difference between 24fps/30fps/60fps?

24fps:

24fps is the most suitable frame rate to further improve picture smoothness and data transmission and storage. It is the frame playback rate that is widely used when transmitting captured frame (video signal) data to film. This is also the playback rate used by most movies.

30fps:

When the Internet gradually emerged, news// and the frame playback rate commonly used for videos used on the Internet.

60fps:

It can provide a smoother and smoother picture look and feel, and is a picture playback rate widely used in high-definition TVs and games. A TV screen only makes sense when the screen refresh rate reaches this value. Otherwise, even if it is a smooth picture, the screen at a low refresh rate will have an impact on the look and feel of the picture.

Refresh rate The refresh rate refers to the number of times the electron beam scans the image on the screen repeatedly. The higher the refresh rate, the better the stability of the displayed image (picture). The refresh rate will directly determine its price, but since the refresh rate and resolution are mutually restrictive, only a monitor with a high refresh rate at high resolution can be called excellent performance.

How many frames should I choose to record videos with my iPhone?

At present, most devices have a refresh rate of 60hz, and the compatibility with 24fps is not perfect. There is no problem with 30fps and 60fps. 30fps can provide longer exposure time in low light, and the photosensitive pressure of cmos is smaller. At the same bit rate, the image quality of 30fps will be better. As for 60fps, it is equivalent to providing you with material that can be lost at 0.5 times the speed.

30pfps is preferred. If you need to do slow motion later, you can use 60fps.
