H264 vs H265 - AVC vs HEVC - What's the difference ?
H.264 (AVC) and H.265 (HEVC) are both standards for video compression used in recording and distributing digital video. 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 processes frames of video using macroblocks, while H.265 processes information using coding tree units (CTUs). CTUs process information more efficiently, which results in a smaller file size and less bandwidth used for your streamed video.
