Bit rate has a certain influence on both video and pictures. For video, the higher the bit rate level, the better the image quality and the clearer the picture quality. For pictures, the higher the code rate level, the clearer the image is when the resolution is fixed.

Bit rate refers to the data stream used by video files per unit time. The popular understanding is the sampling rate, which is the most important part of image quality control in video coding, and the unit used is kbps. At the same resolution, the higher the bit rate of the video file, the smaller the compression ratio and the higher the image quality. The higher the code rate level, the higher the accuracy.
