Methods and systems of the present invention obtain a motion vector between two frames of video image data. Specifically, methods and systems of the present invention may be used to estimate a motion vector for each macroblock of a current frame with respect to a reference frame in a multi-stage operation. In a first stage, an application implementing the process of the present invention coarsely searches a first search area of the reference frame to obtain a candidate supermacroblock that best approximates a supermacroblock in the current frame. In a second stage, the supermacroblock is divided into a plurality of macroblocks. Each of the macroblocks is used to construct search areas which are then searched to obtain a candidate macroblock that best appropriates a macroblock in the current frame. Additional stages may be used to further fine-tune the approximation to the macroblock. The methods and systems of the present invention may be used in optimizing digital video encoders, decoders, and video format converters.
