After the jump, read the FAQ on HTML5 / H.264 >>Q. What is the big change? A. Previously, TEDTalks videos on TED.com were only delivered using the Flash platform. Since Flash is not generally available on mobile devices, you could not watch our videos on TED.com through your phone browser. So we modified our site, and now use an HTML5 video player — showing video encoded to the H.264 codec — to deliver video to the majority of mobile devices accessing TED.com. What it means is: Now, on the iPhone, iPod Touch, and iPad running iPhone OS 3.0 or later, you can watch videos on TED.com, using the phone’s web browser. Since Android devices do not yet support HTML5 video in the browser, the experience is slightly different. You will need to click to view in the native video player.
