A method and apparatus for encoding video includes selecting a prediction motion vector for a current block of a current image frame from respective motion vectors of two or more neighbor blocks of the current block. Then the current block and a neighbor block corresponding to said prediction motion vector are checked to determine whether they are motion correlated. Checking motion correlation includes determining that the difference between the best correlation from the correlation of the current block with one or more neighbor blocks and the correlation of the neighbor block with a block in the previous image frame at a location defined by the prediction motion vector fulfils a predetermined criterion.
