Summary:In some embodiments, a method maintains a list that is configured to store motion vectors from one or more blocks that have been previously processed in a frame. When a current block is in a first set of positions in the frame, the method resets the list by storing a motion vector with a horizontal component and a vertical component equal to zero in the list. The motion vector with the horizontal component and the vertical component equal to zero from the list is used to transcode the current block. When the current block is not in the first set of positions, the method uses a motion vector from the list to transcode the current block.
