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

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

When recording videos with an iPhone, you can choose between HD and 4K video formats in the upper right corner, and there are three numbers to switch between: 24, 30, and 60. What are these three numbers? Which one is better for recording videos? This number is the frames per second (fps).fps.

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. In layman's terms, it refers to the number of frames in an animation or video. FPS measures the amount of information used to save and display dynamic video. The more frames per second, the smoother the displayed action will be. Usually, the minimum to avoid jerky action 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 (in Hz)", such as the "FPS value" we often say in games. When we install and purchase graphics cards and monitors, we will pay attention to the "refresh rate". Generally, we set the default refresh rate to be above 75Hz (i.e. 75 frames per second). For example: a refresh rate of 75Hz means that the screen only scans 75 times in one second, i.e. 75 frames per second. When the refresh rate is too low, we can feel the flickering and discontinuity of the screen with our naked eyes, which has a bad impact on the image display effect and visual perception.
MovieIt plays at a speed of 24 frames per second, that is, 24 still images are continuously projected on the screen within one second. The unit of animation playback speed is fps, where f is the English word Frame, p is Per, and s is Second. In Chinese, it is expressed as frames per second, or frames per second. Movies are24fps, usually referred to as 24 frames.

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

24fps:

24fps is the most suitable frame rate for further improving the smoothness of the picture and data transmission and storage. It is the widely used frame rate when transferring the shooting picture (video signal) data to the film. It is also the playback rate used by most movies.

30fps:

30fpsWhen the Internet gradually emerged, news/TV dramaThe frame rate commonly used in dramas and videos on the Internet.

60fps:

60fpsIt can provide a smoother and more fluid picture viewing experience, which is high-definitiontelevisionAnd the picture playback rate widely used by games. The TV screen will only make 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 affect the picture perception.

Refresh rate refers to the number of times the electron beam repeatedly scans the image on the screen. 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 restricted, only a display that achieves a high refresh rate at a high resolution can be called excellent.

How many frames should I choose when recording a video with an iPhone?

Currently, most devices have a refresh rate of 60hz, and are not perfectly compatible with 24fps, but there is no problem with 30fps and 60fps. 30fps can provide a longer exposure time in low light, and the CMOS has less light-sensitive pressure. At the same bit rate, the image quality of 30fps will be better. As for 60fps, it is equivalent to providing you with a lossless 0.5x speed material.

30fps is preferred, and 60fps can be used if slow motion is required in post-production.
