Abstract: Described herein are techniques related to frame-level quantization parameter (QP) adjustment in video encoding. In particular, a method of implementing a bit rate control (BRC) algorithm is described to dynamically control the QP during the video encoding.

Abstract: Described herein are techniques related to motion and quality adaptive rolling intra (I) macro-block (MB) that is used to encode a particular image frame. In particular, the rolling I MB configuration may be based upon global motion direction, quantization parameter (QP) value, complexity based roll, and/or QP saturation based roll.
