As　the　newest　video　encoding　standard　H.264/AVC　obtained　higher　compression　ratio　at　the　cost　of　huge　coding　complexity,　the　encoding　real-time　sharply　declined,　and　become　the　bottleneck　of　H.264/AVC　in　widely　used.　Aiming　at　the　important　and　time-consuming　encoding　technique　of　H.264/AVC,　combining　the　motion　acuteness　degree　of　macro　block,　the　new　motion　estimation　search　template　and　adaptive　motion　estimation　search　strategy　were　designed　here.　The　simulation　results　show　that　the　proposed　motion　estimation　method　achieve　reduction　of　23.11%　motion　estimation　encoding　time　on　average　compared　with　UMHexagonS　method　which　was　selected　by　H.264/AVC　latterly,　with　almost　the　same　PSNR　and　output　bit-rate,　in　the　premise　of　effectively　improving　the　encoding　speed,　keep　the　low　bit　rate　and　high　quality　of　encoding　advantage　for　H.264/AVC.　©　2011　IEEE.
