Method and system for rate control in a video encoder |
摘要 |
Described herein is a method and system for rate control in a video encoder. The method and system can use relative persistence and intensity of video data in a macroblock to classify that macroblock. On a relative basis, a greater number of bits can be allocated to persistent video data with a low intensity. The quantization is adjusted accordingly. Adjusting quantization prior to video encoding enables a corresponding bit allocation that can preserve perceptual quality.
