Abstract
A method and apparatus are provided for rate control accuracy in video encoding. The apparatus includes a video encoder for encoding image data in a single encoding pass using rate control. The rate control involves defining a quantization step size value and a rounding offset value and refining at least the rounding offset value. The image data is encoded responsive to the quantization step size value and the refined rounding offset value.
