HTML5 Video Tag
The <video> tag is basically a new tag introduced in HTML5 that allows you to embed video in a web page without having to use Flash or any other embeddable plugin, but instead use a player which is built into the browser. It is only supported by advanced browsers like[highlight-green]Â Firefox, Safari, Chrome, and Opera[/highlight-green]. Not Internet Explorer, though IE9 is supposed to support it. For your video to work in all the advanced browsers, it has to be converted into at least 2 formats:[highlight-green] h.264 (Safari and Chrome) and Ogg (Firefox and Opera) [/highlight-green].
VP8, a new codec from On2/Google, may eventually remove the need for multiple versions, but that could take some time.  One is given different options now with the new video tag in HTML5, and the javascript needed to create some of the typical video controls you’d find in other players. It’s library agnostic, meaning you don’t need a library like jQuery to create it which is the best part of implementing such players into your design or website.
