While older codecs used fixed 16x16 pixel macroblocks, HEVC uses flexible CTUs that range from 8x8 up to 64x64 pixels . This allows the encoder to compress large, uniform areas (like a clear blue sky) with a single large block while dedicating smaller blocks to high-detail areas.

HEVC supports the Main 10 profile, enabling over a billion colors compared to the 16 million colors found in standard 8-bit video. This is critical for High Dynamic Range (HDR) content like HDR10 and Dolby Vision. Why HEVC is Essential Today userhevc

High Efficiency Video Coding (HEVC), also known as , is the successor to the long-standing H.264 (AVC) standard and represents a major leap in digital video compression. By utilizing more sophisticated algorithms, HEVC can reduce file sizes by up to 50% compared to H.264 while maintaining the same visual quality.
