    The emerging High Efficiency Video Coding (HEVC) standard employs several efficient coding tools to obtain 50% bit rate reduction than H.264/AVC standard with comparable video quality, but at the cost of high computational complexity. This paper analyzes the performance of fixed CU levels and proposes a level filtering algorithm for inter prediction. A RD cost-based correlation for the 64x64 CU is utilized to do a level filtering for the quadtree structured code unit, which is aimed at reducing the number of fine-processed levels. For the non-64x64 CUs, merge mode and Coded Block Flag (CBF) are used to determine the early termination. Experimental results demonstrate that the proposed method can achieve 0.93% BD-rate loss and 40.36% time reduction on average.
