H.265, also known as HEVC, is a modern video compression standard built to deliver higher visual quality while using the same or even lower bitrate than older formats like H.264, and since bitrate refers to the data volume allocated per second, two codecs at the same bitrate compete with the same data budget, with H.265’s advantage coming from how it uses this limited data more efficiently through flexible block analysis that retains important details by using large blocks for simple regions and smaller ones for detailed areas, allowing more bits to go to faces for sharper, natural-looking results without increasing file 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 describe object movement more cleanly, meaning it stores less corrective data and reduces artifacts like motion smear, ghost trails, and blurring, an advantage that stands out in fast scenes such as action footage or surveillance, and it also enhances gradients, shadows, and low-light areas by preserving subtle shading that older codecs often turn into color steps, producing cleaner dark regions and more natural skies at the same
bitrate.

H.265 wasn’t adopted everywhere right away because achieving its efficiency requires much more complex processing, demanding more CPU/GPU power than older codecs, and many early TVs, computers, and phones simply couldn’t decode it smoothly, causing choppy video, excessive CPU load, or total decoding failure, while hardware support posed an additional barrier since seamless playback typically needs dedicated hardware decoders, which were not widespread when H.265 launched, making manufacturers cautious to avoid compatibility trouble.
