H.265, known officially as HEVC, is a compression standard crafted to achieve superior quality than H.264 even at equal or lower bitrates, and since bitrate represents the video data rate, two codecs running at the same value share the same bit capacity, with H.265 outperforming by using that budget more effectively via adaptive blocks that grow in simple areas and shrink around detail, allowing more bits for faces and fewer for flat regions like skies, yielding crisp images without increasing size.

H.265 enhances motion processing by using more detailed motion prediction between frames, letting it store far less corrective data and minimizing artifacts such as double outlines, streaking, and movement haze, which becomes especially clear in sports shots, and it also improves gradient handling by preserving smooth color shifts that older codecs turn into banding, providing smoother shadows at the same bitrate.

Overall, H.265 achieves higher quality at the same bitrate because it uses less redundant information on details the viewer is unlikely to perceive and instead targets compression where the human eye is most sensitive, though the trade-off is increased encoding/decoding workload, meaning older systems may have difficulty or need additional codecs, yet it remains widely adopted for 4K, streaming, and security systems thanks to clearer images, better motion handling, and more efficient storage without extra bandwidth.

H.265 wasn’t adopted instantly everywhere because reaching its efficiency required much more demanding computation, forcing devices to use significant processing power for encoding and decoding, and early smartphones, PCs, TVs, and embedded systems often couldn’t keep up, resulting in jerky playback, thermal spikes, or files failing to open, and since smooth decoding typically depends on chip-level support, which were not widespread at launch, manufacturers and developers were cautious about setting H.
