What do fps and Hz mean?

FPS: Defined in the field of image, it refers to the number of frames transmitted per second, which is commonly referred to as the number of frames of animation or video.

Hz: refers to the repetition times of 1 second when electric pulse, alternating current waveform, electromagnetic wave, sound wave and mechanical vibration circulate.

FPS measures the amount of information used to save and display dynamic video. The more frames per second, the smoother the motion display. Usually, the minimum requirement for avoiding unsmooth movements is 30. Some computer video formats can only provide 15 frames per second.

Hertz is a very small unit, usually starting with units of order of magnitude such as K (thousands), M (millions), G (billions) and T (trillions).

KHz, kilohertz, is the frequency or sampling rate, generally 44. 1KHz, because this is the standard of music CD.

KHZ: KHz, abbreviated as KHz or KHz, is the unit of frequency of alternating current (AC) or electromagnetic wave (EM), and is equal to 1000 Hz (1000 Hz). This unit is also used to measure and describe the signal bandwidth.

Extended data

FPS can also be understood as "refresh rate (in Hz)", such as "FPS value" often mentioned in CS games. When installing and purchasing graphics cards and monitors, you will notice the "refresh rate". Usually, the default refresh rate is higher than 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, that is, 75 frames per second. But when the refresh rate is too low, we can feel the flicker and discontinuity of the screen with the naked eye, which has a bad influence on the image display effect and visual sense.

The movie is played at the speed of 24 pictures per second, that is, 24 still pictures are continuously shown on the screen in one second. The unit of animation playback speed is fps；;

Where f is the English word frame, p is Per and s is Second. Chinese expression is how many frames per second, or how many frames per second. The movie is 24fps, which is usually called 24 frames.
