First YouTube, Now Vimeo: How HTML5 Could Finally Kill Flash Video

From Gizmodo -

Vimeo has followed YouTube's lead in making its library compatible with HTML5 video. HTML5 video, which currently only works with Safari and Chrome, is expected to become standard feature in all major browsers in a few years' time.

The current video standad, Flash, actually performs terribly on Mac OS X and Linux, is not available in some popular mobile devices and is not even native in browsers that do support it. HTML5, on the other hand, allows video to be rendered in the browser natively, like JPEGs or GIFs are now. It's also simpler and more efficient In fact it would be the obvious choice, notwithstanding the massive investment in Flash video.

However, YouTube, which accounts for probably the most substantial library of Flash video, has also already rendered them in HTML5-friendly h.264 format for the iPhone and Android devices. So with smaller sites like Vimeo joining the bandwagon, the switch may be sooner than expected.
