Editor’s Note: The benefit of using H.265 over H.264 doesn't really become evident until you are compressing videos at 1440p or higher. Given the still limited support of H.265 compared to H.264 on external playback hardware, and given the time it takes to compress to H.265 without visible quality loss, we would not bother converting 2k video from H.264. But for UHD / 4k resolutions like 2160p, the compression factor of H.265 is approximately 9 times better than H.264.
