Abstract
Computer-implemented rate control in encoding one or more video pictures is disclosed. A quantization parameter (QP) to be used for encoding a current picture one of the one or more video pictures is determined using rate control data that takes picture type, picture complexity, and a target bitcount into account in determining the QP. The current picture is encoded into a compressed format using the QP to generate an encoded current picture. The rate control data is updated based on statistical data determined from the encoded current picture.
