YouTube updates video player, adds 720p/480p/360p options
Jan 21, 2010, from http://dvice.com/archives/2010/01/youtube-updates.phpToday YouTube deployed its latest video player, equipped with a new menu that lets users quickly toggle between resolutions. Along the bottom of the window on this video, for instance, there are options for watching the video in 720p, 480p or 360p. This replaces the old buttons labeled "HD" or (confusingly) "HQ." The toggle for increasing the size of the video window itself is now on a separate button. There are a few other cosmetic changes to the page, all outlined here.
HD aficionados like us love the new menu, but then again we know what those numbers mean. Will the majority of the surfing public like it? Or even care? What say you?
