EN The paper presents results on significance of entropy coding used in contemporary hybrid video encoders. Experiments were done with reference to the international video compression standard MPEG-4 AVC/H.264 and the state-of-the-art Context-based Adaptive Binary Arithmetic Coding (CABAC) entropy encoder. Research were done for two different coding scenarios. Experimental results revealed, that application the adaptive entropy encoder within new generation video encoder reduces the size of encoded bitstream 1.5 - 1.8 times, depending on research scenario.
