摘要：
Various embodiments of the present invention relate to systems, devices and method of video encoding that select a quantization parameter set based on a global edge strength value and an available bitrate for a corresponding compressed frame. Quantization parameters are selected using a mathematical correlation between the global edge strength value of the I-frame and an available bitrate/maxim target frame size for the corresponding compressed frame.
