H.265, also referred to as HEVC, is a compression format structured to deliver better visual quality under the same or lower bitrate than H.264, with bitrate meaning the data allowed per second, so both codecs at equal bitrates operate with the same data limit, and H.265 stands out by intelligently using that budget using variable block sizes that expand for simple areas and contract for detailed ones, focusing bits on faces and textures to produce sharper results without increasing the file size.

H.265 strengthens motion handling by making more accurate predictions of how objects move frame to frame, allowing it to store less correction data and reducing artifacts like ghosting, smearing, and blurring, which is especially noticeable in rapid-action shots or security videos, while its improved treatment of gradients and shadows helps avoid the stepping problems found in older codecs, giving smoother color transitions and cleaner low-light areas at identical bitrates.

Overall, H.265 achieves better quality at the same bitrate because it uses its bit budget more efficiently on details the viewer cannot easily perceive and directs compression to regions where the eye is more responsive, though this comes with a heavier processing load, meaning older machines may lag, yet it’s widely embraced for 4K, streaming, and security due to better clarity, improved motion, and strong storage efficiency without added bandwidth.

The biggest reason H.265 didn’t see instant universal adoption, despite its benefits, is that its compression efficiency depends on far more advanced algorithms, which require devices to have stronger CPUs/GPUs for smooth encoding and playback, something early hardware often lacked, leading to stutter, processor overload, or files refusing to decode entirely, and because smooth playback typically relies on built-in acceleration that weren’t common initially, manufacturers avoided making H.
