What is the difference between .hevc and .sgi?

Description: 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.; Image saved in the native graphics format used by Silicon Graphics workstations; can store 8 to 32 bits per pixel; also supports Run-length encoding (RLE) compression for reducing the image file size.
