1. A method of encoding a motion vector in a video coding process, the method comprising:

  • determining one of a plurality of modes for a motion vector prediction process for a current block of video data, the determined mode being a merge mode;

    determining a set of candidate blocks, the determined set comprising a below-left candidate block, a left candidate block, an above candidate block, a right-above candidate block, a left-above candidate block, and a temporal candidate block;

    performing the motion vector prediction process for the current block using the determined mode and the set of candidate blocks, andwherein one candidate block in the set of candidate blocks is designated as an additional candidate block, and wherein the additional candidate block is used in the merge mode if another of the candidate blocks of the set of candidate blocks is unavailable or invalid.
