Bit rate and frame number

Bit rate is the number of bits of data transmitted per unit of time when data is transmitted. Generally, the unit we use is KBPS (thousand bits per second). Popular understanding is the sampling rate, the larger the sampling rate per unit time, the higher the accuracy, processing of files is more close to the original file, but the file with the sampling rate is proportional to the volume, so almost all the coding format value is how to use the lowest rate to the least distortion, around the core derived CBR (fixed rate) and VBR (variable bit rate), from audio ways, the higher the bit rate, the proportion of compressed smaller, the smaller the quality loss, and the closer the audio sound quality. "Bit rate" is the degree of distortion. The higher the bit rate, the clearer it is. Otherwise, the picture is rough and Mosaic.

Simply put, frame number is the number of Frames of images transmitted in one Second. It can also be understood as how many times the graphics processor can refresh itself Per Second. It is usually represented by Frames Per Second. Each frame is a still image, and the rapid and continuous display of frames gives the illusion of motion. Higher frame rates lead to smoother, more realistic animations. The more frames per second (FPS), the more fluid the action will be displayed.

Frames per second (FPS), or Frame Rate, represents a gpu scene that can be updated several times per second. Higher frame rates lead to smoother, more realistic animations. Generally speaking, 30Fps is acceptable, but increasing the performance to 60Fps can significantly improve the sense of interaction and verisimilitudes, while generally speaking, it is not easy to notice a significant improvement in fluency beyond 75Fps. If the frame rate exceeds the screen refresh rate, it just wastes the graphics processing power, because the Monitor can't update so quickly, so the frame rate that exceeds the refresh rate is wasted.

Frame per Second (frame per second, number of updates per second) is used to represent this indicator. When appreciating TV, movie picture, as long as the refresh rate of picture achieves 24 frames/s, can satisfy people's need. Similarly, in a normal game, if the refresh rate reaches 24 FPS, but in some high-speed games (such as shooting games), if the refresh rate is only 24 FPS, then the picture will feel sluggish and not smooth enough.
