Abstract: A block of a video frame may be predicted and encoded using a local affine motion prediction scheme. At least three points within the video frame are selected, each point being adjacent to a respective corner of the current block to be encoded. For each point, a motion search is performed for a template block centered about the point within a reference frame to find a template reference block. The template reference block has a center point that forms an anchor point pair with the corresponding point adjacent to the current block. Using coordinates of the anchor point pairs, affine coefficients for an affine transformation are generated. Using the affine transformation, a prediction block for the current block is generated and used to encode the current block within a bitstream. Providing the local affine motion prediction scheme can improve the prediction of certain blocks with complex motion, increasing compression.
