This paper presents a novel technique to reduce the motion estimation (ME) complexity in H.264/AVC video coding. A low complexity context-aware controller is added to a basic search engine; at coding time the controller extracts from the search engine partial results information on the input signal statistics, using them to dynamically configure the ME search parameters, such as number of reference frames, valid block modes and search area. Unnecessary computations and memory accesses can be avoided, decreasing ME complexity while keeping unaltered coding efficiency for a wide range of applications: bit-rates from tens of kbits/s to tens of Mbits/s and video formats from QCIF to CCIR. The context-aware control can be used with any ME search engine and in the paper is successfully applied to full search and fast ME, as EPZS and UMHS, in the JM10 software model of H264/AVC
