Introducing Wikipedia’s new HTML5 video player

A new video player has been enabled on Wikipedia and its sister sites, and it comes with the promise of bringing free educational videos to more people, on more devices, in more languages.

The player is the same HTML5 player used in the Kaltura open-source video platform. It has been integrated with MediaWiki (the software that runs Wikimedia sites like Wikipedia) through an extension called TimedMediaHandler. It replaces an older Ogg-only player that has been in use since 2007.

The new player supports closed captions in multiple languages.

Based on HTML5, the new player plays audio and video files on wiki pages. It brings many new features, like advanced support for closed captions and other timed text. By allowing contributors to transcribe videos, the new player is a significant step towards accessibility for hearing-impaired Wikipedia readers. Captions can easily be translated into many languages, thus expanding their potential audience.

TimedMediaHandler also comes with other useful features, like support for the royalty-free WebM video format. Support for WebM makes it possible to seamlessly import videos encoded to that format, such as freely-licensed content from YouTube’s massive library.

Even further behind the scenes, TimedMediaHandler adds support for server-side transcoding, i.e. the ability to convert from one video format to another, in order to deliver the appropriate video stream to the user depending on their bandwidth and the size of the player. For example, support for mobile formats is available, although it is not currently enabled.

The player’s “Share” feature provides a short snippet of code to directly embed videos from Wikimedia Commons in web pages and blog posts, as is the case here.

Sponsored by Kaltura and Google, developers Michael Dale and Jan Gerber are the main architects of the successful launch of the new player. With the support of the Wikimedia Foundation’s engineering team and Kaltura, they have gone through numerous cycles of development, review and testing to finally release the fruits of years of work.

Efforts to better integrate video content to Wikipedia and its sister sites date back to early 2008, when Kaltura and the Wikimedia Foundation announced their first collaborative video experiment. Since then, incremental improvements have been released, but the deployment of TimedMediaHandler is the most significant achievement to date. (more…)

Video Labs: Kaltura HTML5 Sequencer available on Wikimedia Commons

I am happy to invite the Wikimedia community to try out the latest Kaltura HTML5 video sequencer as part of a Wikimedia/Kaltura Video Labs project that can now be used on Wikimedia Commons with resulting sequences visible on any Wikimedia project. For those that have been following the efforts, it has been a long road to  deliver this sequence editing experience within the open web platform and within the MediaWiki platform. This blog post will highlight the foundational technologies in use by the sequencer in its present state and outline some of the upcoming features in Firefox 4, and enhancements to the sequencer itself that are set to improve the editing experience.

If you want to just jump into editing, please check out the commons documentation page and play around with the editor and let us know what you think. This project is early on in its development. Your bug reports,  ideas, feedback and participation will help drive future features and how these tools are used within Wikimedia projects.

If you’re interested in Video on Wikipedia in general, please consider joining the Wikivideo mailing list which will cover a wide range topics, including the sequencer, collaborative subtitles, timed text, video uploading, video distribution, format guidelines, and campaigns to increase video contributions to the site.

And finally, if you are in the New York area consider checking out the Open Video Conference coming up October 1st to the 3nd, which will be a great space to hack on open video and work on ideas for the future of video on Wikimedia projects.


Kaltura sponsors Michael Dale, open source video developer

As many of you may know, Wikimedia is working with Kaltura, Inc. to explore collaborative video editing in the Wikimedia projects. I’m very happy to announce that Kaltura has decided to support the further development of a 100% open source video editing solution integrated into MediaWiki. To this end, Kaltura is sponsoring Michael Dale, lead developer of the MetaVid project, to work in the Wikimedia Foundation offices in San Francisco beginning in early August.

Michael will work on adding support for video editing operations and other video-related functionality to MediaWiki, with a rich user interface built entirely on open standards like Ogg Theora. Michael’s work priorities will be coordinated between Kaltura and WMF. I am hoping that we can make incremental improvements to Wikimedia’s video capabilities that will start to become visible to users soon. :-)

Michael Dale is currently a Research Associate at the University of California Santa Cruz and the lead developer for the MetaVid project. MetaVid is a community archive project for public domain US legislative footage. The MetaVidWiki software (which runs the archive) is a free software extension to MediaWiki that enables community engagement with audio/visual media assets and associative temporal metadata. Michael has been involved free & open media adoption on the web in collaboration with the and annodex organizations.

Please join me in welcoming Michael!

Kaltura and Wikimania 08 collaborative video editing

Kaltura, who Wikimedia has been working with over the last few months on the exploration of open-source, collaborative video editing on Wikimedia projects, have developed a Wikimania video wiki leading up to this year’s conference in Alexandria. Kaltura is also a generous benefactor of Wikimania this year, providing financial support to make the event possible.

They’re inviting project volunteers and enthusiasts (whether attending or not) to try their hand at collaborative video uploading/editing/improving.  Share your video from your travel to Egypt – or if you can’t make it, why not edit in your comments or questions for participants?

Invitation from Lisa Bennet, Director of Public Relations and Marketing, Kaltura

Hi Everyone,

As Wikimania is right around the corner, we’ve added a new great way to share information about the event. I would like to invite you to the Wikimania Video Site where you can create collaborative videos. The site already has some videos where people can add their expectations for the event or share why they can’t join us this year, and there will be computer stations at Wikimania for attendees to add videos and pictures in real-time from Alexandria. Hopefully, it will be a great resource for people that could not be there in person to see the highlights, and for the attendees to document the event.

Check it out at:

The site is hosted on the Kaltura devwiki and uses the collaborative video technology from Kaltura, which the Foundation partnered with late last year to explore adding videos to Wikipedia and other projects.

You’re invited to share your experiences from Wikimania, play with the technology, and provide your feedback.

Jay Walsh, Head of Communications
