Description: Video file encoded with the MPEG-2 codec, which is mainly used for over-the-air, satellite, and cable digital TV signals and DVD video; uses lossy compression for audio and video to significantly reduce the size of the video data; not as efficient as the H.264 format.; The High Efficiency Video Coding (HEVC) file, commonly known by its file extension .hevc, represents a video compression format designed to substantially improve coding efficiency compared to its predecessor, H.264/AVC. Aimed at enabling higher resolution video content such as 4K and 8K, HEVC is adept at maintaining high-quality video at roughly half the bitrate, significantly reducing file sizes without compromising on visual fidelity. This efficiency makes HEVC particularly valuable in streaming media applications.
