Change subject: Enable 720p and 1080p .ogv Ogg Theora transcodes ...................................................................... Enable 720p and 1080p .ogv Ogg Theora transcodes Variable bitrate HD transcodes aren't as huge overall as I had feared -- see https://phabricator.wikimedia.org/T108172#2340964 720p plays back in ogv.js on any MacBook Pro I've tested, and on 64-bit iOS devices such as iPad Air. 1080p plays back acceptably on Macs and iPad Pro as well. (MS Edge provides similar performance as Safari on Windows 10, while IE stumbles along at half the decode speed.) For the 4K rendering of 'Tears of Steel', 720p renders to an average 2.1 Mbps and 1080p to average 4.0 Mbps, which is actually about the same as our current constant bitrate WebMs. Note that instantaneous bandwidth peaks rather higher during scenes with high complexity!
