YouTube, Vimeo Try Out HTML 5.0 Video

YouTube this week announced support for a prototype player that uses HTML 5, and Vimeo has jumped in as well.

The prototype YouTube player is available here, while Vimeo's new palyer can be enabled by clicking the "switch to HTML5 player" link below its videos. Both players can only use the Chrome, Safari, and the ChromeFrame plugin for Internet Explorer.

HTML 5.0 received its coming-out party at the Google I/O conference in May 2009; in December, Google said that it would eventually drop its Google Gears offline utility in favor of HTML 5.0.

For video, HTML 5.0's chief advantage is that it includes video as a supported tag. According to proponents, this allows simplified coding, and the ability to jump in and out of video streams at various places without the need for buffering.

As such, however, the first uses of HTML 5.0 are little more than prototypes. "Our support for HTML5 is an early experiment, and there are some limitations," YouTube said in a blog post authored by Kevin Carle and Chris Zacharias, both engineers for the company. "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). We will be expanding the capabilities of the player in the future, so get ready for new and improved versions in the months to come."

Vimeo's Brad Dougherty also noted that the new player won't work on all Vimeo videos - although about 90 percent are supported - and the HTML 5.0 player is only enabled on videos viewed directly from the Vimeo site. As of Thursday, the Vimeo HTML 5.0 player also could not play videos back in full-screen mode.

"The simple fact is right now h264 allows us the most flexibility to display on many devices and many players with the same file,' Dougherty said. "When that changes, so will we."
