Abstract: Techniques related to parallel block video coding using an adaptive wavefront split are discussed. Such techniques include adaptively applying a wavefront split in a video frame based on a frame level quantization parameter of the video frame, an encode duration of a previous frame, and/or image content of the video frame.

Abstract: Techniques related to reduction of artifacts in parallel block coding mode selection for video are discussed. Such techniques include, for blocks along a parallel processing split boundary of a video frame, coding mode selection that divides a block into sub-blocks, performs motion estimation for the sub-blocks with skip check disabled and using distortion and coefficient coding cost but exclusive of motion vector coding cost, and evaluates a skip check for the block using the sub-block motion vectors.
