From the Stone Age to the present day, visual communication can be described as a form of communication that has evolved over various topics, from design to technology. As a result of globalization and the transformation of digital citizenship, services such as the Internet have come into the world. With the advent of mobile phones, computers, and television, more and more people are viewing and sharing videos, the need for a lower cost and higher quality methodology. The H.264 standard was successfully introduced in 2003 as another answer to that problem. The H.264 standard, which supported 1920 x 1080 Full HD resolutions, was no longer more practical than 4K resolutions. A decade later, with the introduction of the H265 in 2013, video usage became even more efficient. This was introduced with the combination of MPEG and ITU-T. H.265 codex mostly targets higher resolution video, such as 4k and 8k. Thru this paper, we are looking into the comparison of the technology used in H.264 and H.265. Specially H.264 and H.265 workflow, Transformation and Quantization techniques used, coding Units, Entropy Coding methods, etc. The quality of the output video is expected to be well preserved to the point where the frame concealment algorithm proposed leaves a very little negative impact on the video
