An embodiment of a semiconductor package apparatus may include technology to determine a residual error based on coding unit information, and determine a candidate coding unit and an associated rate distortion cost based on the residual error. An embodiment may additionally or alternatively include technology to partition a first coding unit into two or more smaller coding units based on a partition message, accelerate processing of at least one of the two or more smaller coding units, and estimate motion fora frame based at least partially on results of the accelerated processing. Other embodiments are disclosed and claimed.

Example apparatus to encode video disclosed herein include an encoder to perform an intra search first stage based on source pixels of a source video frame to determine first intra candidates to predict a block of the source video frame. In disclosed examples, the encoder is also to perform an intra search second stage based on reconstructed pixels of neighboring blocks associated with the first intra candidates to determine a second intra candidate. In disclosed examples, the encoder is further to encode the block of the source video frame based on the second intra candidate.

A system for video encoding is described herein. The system includes a processor to execute a multi-pass palette search and mapping on a video frame to generate palette candidates. The processor is to execute an intra block copy prediction on the video frame to generate intra-block-copy candidates. The processor is to also calculate a rate distortion optimization (RDO) cost for a set of generated residuals, the palette candidates, and the intra-block-copy candidates. The processor is to further also execute a final mode decision based on a comparison of the rate distortion optimization (RDO) costs.
