Abstract:
Techniques are described to unify the motion vectors of sub-blocks of an affine block and the motion vector information that is stored and used as predictors for determining motion vectors for subsequent blocks. A video coder may determine that the motion vector for a sub-block is the same as the motion vector information that is used to determine motion vectors for subsequent blocks.
