This paper summarizes our efforts in describing the main concepts of the video coding and explaining how these concepts achieve the video compression. Due to the large size of the raw digital video, it should be stored or transmitted in a compressed format. A lot of video compression standards were implemented to convert the large bits of the raw digital video into a compact format with a small number of bits. Also this paper presents the basic characteristics and the properties of the video compression techniques like H.261, H.263, MPEG-1, MPEG-2, MPEG-4, MPEG-7and H.264 and provides a comparative study to explain the strength and the limitation of each technique. Also this paper introduces FFMPEG codec as a research tool for studying the performance comparison analysis of the H.264, MPEG-4 and MPEG-2 compression techniques. Experimental quality comparisons measure the PSNR (peak Signal to Noise Ratio) and VQM (Video Quality Model) of H.264, MPEG-4 and MPEG-2 for several video sequences and bit rates.
