Wikimedia Community Debates H.264 Support On Wikipedia Sites

by Michael Dale

Wikimedia has been a long time supporter of royalty free formats, but is now considering a shift in their position. From the RfC:

To support the MP4 standard as a complement to the open formats now used on our sites, it has been proposed that videos be automatically transcoded and stored in both open and MP4 formats on our sites, as soon as they are uploaded or viewed by users. The unencumbered WebM and Ogg versions would remain our primary reference for platforms that support them. But the MP4 versions would enable many mobile and desktop users who cannot view these unencumbered video files to watch them in MP4 format.

This has stirred a heated debate within the Wikimedia community as to whether the mp4 / h.264 format should be supported. Many wikimedia regulars have weighed in, resulting in currently an even split between adding the H.264 support or not. The request for comment is open to all users of Wikimedia, including the broader community of readers.

What do you think about supporting H.264 on Wikimedia sites?

Kaltura and Google Bring Enhanced Video Support to Wikipedia

by Michael Dale

Kaltura is happy to announce the deployment of a greatly enhanced video platform on the Wikimedia network of sites. Wikipedia has added support for enhanced video and audio capabilities using Kaltura’s player technology! Wikimedia sites include the English Wikipedia and the Wikimedia Commons media repository.

Wikipedia and its sister sites have enabled a new video player (using Kaltura’s HTML5 video player) with the promise of bringing free educational videos to everyone on any device in any language.

Video is an important form of information, and video based knowledge is rich and illustrative, and will add a lot to the already rich and amazing content that Wikipedia has. Kaltura is proud to have its open source technology and HTML5 video player deployed to bring video to hundreds of millions of Wikipedia users. Our mission has always been to enable any video to reach any user on any device. We have been doing this working with our educational, enterprise and media customers, transforming the way people learn, work and entertain with video.

After an extended beta, many infrastructure integration efforts, and review cycles, Wikimedia sites now feature the same Kaltura HTML5 player used within the Kaltura Open Source Platform. A critical feature for the foundation’s commitment to accessibility and support for many languages was multi-lingual timed text support. Leveraging the Kaltura technology, the shared media repository assets can easily be embedded into Wikimedia network of sites, while supporting captions per the local language of the wiki. This update also adds robust transcoding support, along with ingestion and delivery of Googles WebM encoded videos.

Kaltura HTML5 Sequencer available on Wikimedia Commons

by Zohar Babin

Our very own Michael Dale has just posted on the Wikimedia blog about the new Kaltura HTML5 Sequencer. We believe this marks a stepping stone in the world of online media (at least in the Firefox 4 beta, where it runs the best). Similar in spirit to other simple desktop editors like Apple’s iMovie, the Sequencer is capable of producing rich video sequences made of videos (& trimmed parts), images, and audio files, and apply transitions in between. On the project’s roadmap, you’ll find the use of SVG for overlays and advanced effects and transitions using CSS or Canvas manipulations. The Sequencer uses a subset of SMIL as its EDL (Here, the EDL is an XML file representing the flow of the video sequence, assets used, transitions, etc.) so that it is possible to always come back and manipulate the video sequence. The EDL also makes the video searchable and indexable for credits and remixing. When the sequence is ready to be published, the Sequencer uses the Firefogg Firefox extension to render the sequences on client side, producing a fully downloadable flattened video file. While the project is still in its infancy — awaiting web browsers to evolve to provide stable cross-browser media playback experiences — we believe this is more than just a cutting edge proof of concept. The Sequencer will eventually find its way into projects like Wikipedia, and when used with other collaboration tools like the Add Media Wizard, the Sequencer will become a powerful online video collaboration tool, empowering content creators with simple ways to create rich collaborative video without leaving the browser. If you feel like checking out the source and becoming a collaborator on this project, you can find the project page and source at: Kaltura HTML5 Video & Media JavaScript Library.
