Abstract:
A video coder may be configured to determine to use a decoder side motion vector refinement process, including bi-lateral template matching, based on whether or not weights used for bi-predicted prediction are equal or not. In one example, decoder side motion vector refinement may be disabled when weights used for bi-predicted prediction are not equal.
