HEVC, also known as H.265, is a video compression standard that was developed to succeed the widely-used H.264/AVC standard. The main goal of HEVC is to provide a more efficient way of compressing video content, allowing for smaller file sizes and faster transmission times while maintaining similar or better video quality. HEVC achieves this through a number of advanced techniques, including improved motion prediction, more efficient entropy coding, and better support for 4K and high-dynamic-range (HDR) content.
But the real secret for 100MB files is . A typical 1080p video needs ~5-8 Mbps for good quality. A 100MB movie over 90 minutes runs at roughly 0.15 Mbps (150 Kbps) . 100mb movies hevc full
