Google released an experimental version of “HTML5-supported player” for YouTube. “Our support for HTML5 is an early experiment, and there are some limitations. HTML5 on YouTube doesn’t support videos with ads, captions, or annotations and it requires a browser that supports both the video tag and h.264 encoded video (currently that means Chrome, Safari, and ChromeFrame on Internet Explorer),” Google. To try it out, go to HTML5 page via TestTube or visit this page and join the experiment. This’ll enable HTML5 video for your browser, provided that it’s one of the browsers mentioned above and fits in with the parameters we already referenced. (If you’ve opted in to other experiments, you may not get the HTML5 player.) You can also enable Feather watch along with HTML5 video for an even simpler, faster YouTube experience.
