Recently I was asked to visually illustrate the data rate difference between two HEVC files, one encoded with CBR at 6 Mbps, the other using capped CRF with the same cap.

For years, H.264 has remained dominant simply because it played everywhere; but as videos grow larger, faster, and deeper in color, the cost of distributing H.264 …
