What is H.265?
H.265 (also known as HEVC, short for High Efficiency Video Coding) is a video compression standard whose predecessor is H.264/MPEG-4 AVC. H.265 HEVC ensures to deliver video quality identical to H.264 AVC at only half the bit rate. Learn more about H.265 at wikipedia
In general, H.265 has several big advantages over H.264, including better compression, delicate image and bandwidth saving. For more detailed differences, please read H.265 vs H.264 comparison table.
