Abstract: An example device for coding video data includes a memory configured to store video data, and one or more processors implemented in circuitry and configured to code a first motion vector difference (MVD) representing a difference between a first motion vector of a current block of video data predicted using affine prediction and a first motion vector predictor (MVP) for the first motion vector, predict a second MVD from the first MVD for a second motion vector of the current block, and code the current block using affine prediction according to the first motion vector and the second motion vector. Predicting the second MVD from the first MVD in this may reduce bitrate of a bitstream including coded video data, as well as improve processing efficiency.

Abstract: An apparatus configured to encode or decode video data that includes a memory configured to store at least one reconstructed sample of video data and at least one processor, in communication with the memory, that is configured to identify at least one reconstructed sample, determine at least one extended angular intra prediction mode to use for intra prediction of at least one sample of a current block, intra predict, using the at least one extended angular intra prediction mode, at least one sample of the current block based on the at least one reconstructed sample, extended angular intra prediction modes including angular intra prediction modes other than angular prediction modes between horizontal -45 degrees and vertical -45 degrees, and encode or decode the current block based on the at least one predicted sample.
