Quantization post-processing encoding systems and methods are described. In one embodiment an encoding system includes a quantization module, a quantization coefficient buffer, and a quantization post-processing module. The quantization module performs quantized encoding of information. The quantization coefficient buffer stores results of the quantized module. The quantization post-processing module provides adjustment information to the quantization coefficient buffer for utilization in adjusting the results from the quantized module stored in the quantization coefficient buffer without unduly impacting image quality.
