Disclosed herein are representative embodiments of processing digital image data. In one exemplary embodiment disclosed herein, for a current block of a first frame of digital image data, a list of motion vector prediction information for the current block is populated with candidate motion vector prediction data that includes default motion vector prediction data. In another exemplary embodiment disclosed herein, at least a portion of a coded video bitstream is received and a merge flag for a current block in a current frame is decoded. After the merge flag is decoded, at least one merge candidate for the current block is determined.
