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

H.265 also improves how motion is handled between frames by offering significantly better motion prediction, since video contains repeated information and H.265 can map object movement more precisely, meaning it stores less corrective data and reduces artifacts like smearing, ghost trails, and motion blur, an advantage that stands out in fast scenes such as high-motion shots or surveillance, and it also enhances gradients, shadows, and low-light areas by preserving subtle shading that older codecs often turn into banding, producing cleaner dark regions and more natural skies at the same bitrate.

Overall, H.265 offers higher quality at equal bitrate by spending fewer bits inefficiently on parts the viewer doesn’t notice and emphasizing compression on areas where the eye is more tuned, though this requires higher computational resources, which older systems may fail to handle well, yet it has become widely adopted for 4K, streaming, and surveillance thanks to sharper images, smoother motion handling, and more efficient storage without raising bandwidth needs.
H.265 wasn’t rolled out everywhere instantly because its efficiency comes at the cost of much heavier processing demands, requiring stronger CPUs on both the encoder and viewer side, and early devices like TVs, mobile phones, and laptops often couldn’t decode it properly, causing stuttering, overworked CPUs, or files that wouldn’t open, and hardware acceleration was another obstacle since reliable playback usually needs hardware acceleration, which many devices lacked at the time, making developers hesitant to switch because of potential user device failures.
