Unlike H.264 macroblocks, H.265 processes information in what’s called coding tree units (CTUs). H.265 (also called HEVC, or High Efficiency Video Coding) allows for further reduced file size, and therefore reduced required bandwidth, of your live video streams.

H.265 is newer and more advanced than H.264 in several ways. While that might sound confusing, here’s what you need to know: The H.264 algorithm can substantially lower bitrates better than previous standards, and is widely used by streaming internet sources like Vimeo, YouTube, iTunes, and more. Macroblocks typically consist of 16x16 pixel samples that can be subdivided into transform blocks, and may be further subdivided into what are known as prediction blocks. It works by processing frames of video using a block-oriented, motion-compensation-based video compression standard. H.264 (also called AVC, or Advanced Video Coding) is an industry standard for video compression that allows for the recording, compression, and distribution of digital video content. There’s more to learn about macroblocks, CTUs, and these standards, so keep reading this detailed guide.

CTUs process information more efficiently, which results in a smaller file size and less bandwidth used for your streamed video. H.264 processes frames of video using macroblocks, while H.265 processes information using coding tree units (CTUs). Why would you choose one over the other? The main difference between H.264 and H.265 is how each processes information and the resulting video file size and bandwidth consumption used with each standard. H.264 (AVC) and H.265 (HEVC) are both standards for video compression used in recording and distributing digital video. The Major Difference Between H.264 and H.265
