H.265, or HEVC, is a modern codec designed to provide higher image quality compared to H.264 while maintaining the same or even lower bitrate, where bitrate represents the bits-per-second allotment, meaning both codecs at equal bitrates share the same bit budget, and H.265’s key strength is its smarter use of that budget through adaptive block structures that become large in simple areas and small in detailed ones, letting it concentrate bits on key details like faces and motion so the image looks sharper without growing 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 movement haze, which is especially noticeable in rapid-action shots or security videos, while its improved treatment of gradients and shadows helps avoid the striping problems found in older codecs, giving smoother color transitions and clearer low-light areas at identical bitrates.

Overall, H.265 achieves higher quality at the same bitrate because it avoids spending unnecessary data on details the viewer is unlikely to perceive and instead focuses compression where the human eye is most responsive, though the trade-off is greater computational complexity, meaning older systems may struggle 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.

The main reason H.265 was not adopted everywhere immediately, despite its clear advantages, is the trade-off required for its higher efficiency: it uses far more computationally heavy mathematical processing for compression and playback, meaning devices need greater computational resources to handle it, and early computers, phones, TVs, and embedded systems often lacked the capability, causing stuttering, processor spikes, or an inability to open files, and hardware support was another barrier because smooth playback typically requires dedicated hardware decoders, which were not yet common, so manufacturers hesitated to adopt H.
