A macro-block (MB) quantization reactivity compensation method for a video encoder is provided. The method calculates a reference picture quantization value based on a calculated picture complexity. This predicted reference quantization is combined with the bits-used reactive macro-block reference quantization value to determine the final macro-block reference quantization value. This MB reference quantization value is also made adaptive to the VBV buffer fullness, as well as to the predicted change of the current picture complexity. A video encoder and an article of manufacture that comprises computer readable program code for execution of the method are also provided. |
