H.265, also called HEVC, is a video compression method designed to offer higher visual quality using the same or a lower bitrate than H.

H.265 boosts motion handling by predicting movement between frames with higher precision, allowing the codec to use less corrective data and cut down on streaking, ghost trails, and blur trails, making a big difference in fast-motion footage like surveillance clips, and it also improves how gradients and shadows appear by maintaining gradual shifts that older codecs often distort into stepping, resulting in smoother dark areas and more natural results at the same bitrate.
Overall, H.265 achieves better quality at the same bitrate because it spends fewer bits on details the viewer cannot easily perceive and allocates compression to regions where the eye is most attentive, though this comes with more computational demand, 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.
H.265 wasn’t adopted everywhere right away because achieving its efficiency requires much heavier computation, demanding more CPU/GPU power than older codecs, and many early TVs, computers, and phones simply couldn’t decode it smoothly, causing stuttering playback, excessive CPU load, or total decoding failure, while hardware support posed an additional barrier since seamless playback typically needs specialized decode units, which were not widespread when H.265 launched, making manufacturers cautious to avoid support headaches.
