H.264 is an advanced video coding standard with wide application prospects. It has excellent compression performance and excellent image coding quality. It is widely used in many common fields such as video transmission, video storage and video editing. H. 264 uses a lot of complex computation, in which motion estimation takes up the largest amount of computation. Efficient motion estimation algorithm is of great significance to improve the efficiency of video coding. In this paper, the motion estimation and its typical algorithms of H.264 video coding standard are studied, focusing on UMHexagons (hereinafter referred to as UMH), the initial prediction order of motion vector and 5×5 spiral full search template is optimized, greatly improving the search efficiency.
