What Is H.265?
Successor to H.264, H.265 (aka. HEVC), is said to revolutionize video coding efficiency to provide greatly improved video quality at the same bit rate with H.264 on account of double data compression ratio and to support 4K/8K UHD with a resolution of up to 8192x4320 pixels. Comparable to the precious standard, H.265 is more network-friendly for lower bandwidth needed to play videos at the same level of quality, which means watching x265 4K or 8K videos online more smoothly. In addition, a H.265 encoded video takes up less space, making it more suitable to be saved on devices with limited storage.
