Abstract: A video coding system including an acceleration device including input circuitry configured, for each of a first plurality of video frames to be encoded, to receive an input including at least one raw video frame and at least one reference frame, and to divide each of the first plurality of video frames to be encoded into a second plurality of blocks, and similarity computation circuitry configured, for each one of the first plurality of video frame to be encoded: for each the block of the second plurality of blocks, to produce an intra-prediction hint and an intra-prediction direction. Related apparatus and methods are also provided.

Abstract: There is provided a computerized method and system of optimized video encoding of an input video sequence corresponding to a plurality of input frames, the method comprising: obtaining an input frame; performing a first encoding of the input frame using a first encoding parameter determined in accordance with a target bit-rate, giving rise to a first encoded frame; performing a second encoding of the input frame using an iterative quality-driven encoding scheme initialized with an initial second encoding parameter, the initial second encoding parameter determined based on the first encoding parameter, the second encoding performed in an attempt to seek a second encoded frame having a lower bit-rate than the first encoded frame and meeting a quality criterion relative to the first encoded frame; and in case of the second encoded frame being found, providing the second encoded frame as an output frame corresponding to the input frame.
