Abstract

For AVC/H.264 video encoders, the paper describes a simple global model that defines a relationship between the bitrate and the quantization step Qstep for I-, P- and B-frames. Proposed is a general model for any video shot. As such a model must be dependent on video content, the model parameters have to be estimated from experimental data individually for each video shot, and individually for each frame type. The model is defined by formulas given individually for 3 intervals covering whole eligible range of Qstep values. Extensive experiments with numerous test video sequences have proved good accuracy of the model proposed.
