In various video coding standards, the industry has been trying to chase "high compression ratio (smaller data volume)", while ensuring "high video quality" algorithm. Fish and bear's pauses are uncomfortable, video coding is a folded game. The setting of the "video code rate" represents this colorful choice. The higher the code rate, the larger the amount of data, the better the video quality, the smaller the code rate, the smaller the amount of data, the worse the quality of the video. < / P> 1234567891011121314 However, after the code rate is large enough, the improvement of the video quality of the code rate will become insignificant, so this code rate threshold is very important. Online article "Video Encoding Settings For H.264 Excellent", the code rate threshold at different video resolutions is tested for H.264 video encoding. It introduces a set of resolutions, rate settings, and reasoning behind these selections, and the reasoning behind the high quality H.264 video coding. This article helps us answer: for H.264 video coding (invalid for other video coding format), give a video resolution, what video code rate is to be set, in order to get the "most cost-effective" high quality Video screen. For the H.264 encoding format, according to different resolutions, it is recommended that the corresponding code rate configuration relationship is shown in the following figure: Widescreen Non-wide screen
