Encoding.com (http://www.Encoding.com), a video encoding service provider, has announced the expansion of its video format library to include WebM and Ogg Theora. Along with existing support for H.264, Encoding.com now has encoding presets to support all popular Internet browsers.

Video content developers now have a one-stop service for converting videos to high-quality formats across all HTML5 browsers, including Internet Explorer, Firefox, Safari, Chrome, and Opera, and mobile devices including iPhone / iPad, Android, Blackberry, Nokia and Samsung, says Jeff Malkin, president of Encoding.com.

“While HTML5 delivers on the promise of viewing videos across the web without the need for browser plugins, there is no standardization of video codecs and containers across the various browsers and mobile devices,” he says. “Content providers who want to maximize their viewership must therefore encode video to many different formats for ubiquitous coverage. Encoding.com has long provided an easy-to-use preset for encoding to H.264, the most popular HTML5 video format. With today‚Äôs announcement Encoding.com adds support for Ogg/Theora and WebM/VP8 both utilizing the Vorbis Audio codec.”

HTML5 is being developed as the next major revision of HTML (HyperText Markup Language), the core markup language of the web. It’s touted as the next standard for HTML 4.01, XHTML 1.0 and DOM Level 2 HTML and is designed to to reduce the need for proprietary plug-in-based rich internet application (RIA) technologies such as Adobe Flash, Microsoft Silverlight, and Sun JavaFX.
