A process for reducing data movement and thereby reducing the power consumption and reducing cycle requirements for video compression techniques is described. A process for improving data acquisition process for motion estimation when transitioning from one macroblock to next adjacent macroblock by selective replacement of motion estimation area is described. One process involves replacing a non-overlapped search area in one (left) region belonging to one macroblock with the new search area in another (right) region belonging to the next adjacent macroblock. Another method involves replacing a non-overlapped search area in one (left) region with the new search area in another (right) region employing a cyclic memory structure. A third method in using the overlapped search areas for vertically adjacent regions is described. The processes involve improvements to MPEG-1, H.261, MPEG-2/H.262, MPEG-4, H.263, H.264/AVC, VP8, and VC-1 video coding standards and any other video compression technique employing a motion estimation technique.
