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.
