H.265, also known as HEVC (High Efficiency Video Coding), is a video compression standard that allows for high-quality video streaming and storage. It is designed to reduce the file size of video content while maintaining excellent visual quality, making it ideal for 4K and 8K video formats. This technology is widely used in various applications, including streaming services, Blu-ray discs, and video conferencing. By compressing video more efficiently than its predecessor, H.264, H.265 enables faster downloads and less bandwidth usage, benefiting both content providers and viewers.
