Original Abstract Submitted
A method for determining a prediction block for decoding or encoding a current block in a current picture of a video stream. The method includes obtaining a pair of initial motion vectors comprising a first and a second initial motion vector. The method also includes determining whether to refine the initial motion vectors. The step of determining whether or not to refine the initial motion vectors comprises: i) determining whether a first prediction scheme and/or a second prediction scheme is enabled and ii) determining to refrain from refining the initial motion vectors as a result of determining that either the first prediction scheme or second prediction scheme is enabled or determining to refine the initial motion vectors as a result of determining neither the first prediction scheme nor second prediction scheme is enabled.
