A codec is a software that encodes and compresses a video for storing or before transporting through networks.The process of video encoding has become a major part of information technologies.Hence, a variety of codecs has been developed through the years.in this paper we provide an analysis of the two wildly used video coding standards H.264 and H.265.In order to elaborate this study, for each one of the codecs, we calculated four essential metrics: PSNR, SSIM, VIF and VMAF.We report a higher performance of H.264 for most of the metrics however in terms of size the H.265 presented a higher compression rate.Moreover, in terms of Energy consumption, H.265 showed lower energy consumption than H.264.
