A method for implementing motion estimation comprising the steps of (A) performing a motion estimation search on one or more blocks of sub-sampled images to generate a first plurality of motion vector scores, (B) applying a first adjustable bias to any one or more of said first plurality of motion vector scores with a lowest sum of absolute differences score, (C) selecting a motion vector with a lowest adjusted score in response to applying the first adjustable bias, (D) performing a motion estimation search on one or more blocks of non-sub-sampled images to generate a second plurality of motion vector scores with the selected motion vector with the lowest adjusted score, (E) applying a second adjustable bias to any one or more of the second plurality of motion vector scores with the lowest sum of absolute differences score and (F) selecting a final motion vector for each target block position.
