A device for decoding video data can be configured to store a table of history-based motion vector predictors (HMVPs); determine motion information for a first block of the video data; add the motion information for the first block to the table of HMVPs in response to determining that the first block is located at a bottom-right corner of a motion estimation region (MER); and use the table of HMVPs to decode a second block of the video data.
