H.265, also known as High-Efficiency Video Coding (HEVC), is the successor to the ubiquitous H.264 standard. It offers double the data compression ratio at the same level of video quality, or significantly improved video quality at the same bit rate. The "X" in H265X Player represents the extended capabilities of this update, which goes beyond standard decoding to offer a comprehensive suite of tools for both casual viewers and professionals.
The previous version, v4.2.7, had introduced “smart rendering.” That was the phrase the devs used. Smart rendering.
