Size: H.265/HEVC reduces the file size by about 39-44% at the same quality compared to H.264. So how does HEVC or H.265 advantages over H.264? Still here, just scroll down for the answer.Īpproved date: The first version of H.264 was standardized in 2003 while HEVC was formally ratified as a standard 10 years later. HEVC vs H.264: Since HEVC or H.265 is the successor to avc H.264, there is bound to be a comparison between HEVC/H.265 and H.264. HEVC/H.265 VS H.264, AV1 or Other Video Codecsġ. That That's way HEVC is widely used to compress video with 4K or even 8K resolution. Plus, the quality of video encoded by HEVC is substantially enhanced under the same bit rate. The size of code unit is determined by the regional information. HEVC/H.265 codec manages to offer the same level of video quality but half the size of video compared to its successor H.264/MPEG-4 AVC, which means these 4K contents need only half the data to stream over YouTube. Due to the less efficiency in video compression with H.264, coding distortion situations are likely to happen in border areas. But for the 4k video with 8.3 megapixels, it seems to be impossible to store or transmit the UHD video if compressed with H.264. Those videos from the video streaming services are generally in 1080p (2.1 megapixels) or 720p (0.9 megapixels). H.264/MPEG-4 AVC, the predecessor of HEVC, is famous for compressing huge amount of information of a video for steaming over YouTube, Netflix, Vimeo, etc. Why Use HEVC/H.265 for 4K/8K Videos Instead of H.264
