Annotrax combined the concept of channeled annotating with a video search engine and an highly interactive video player. This project relied heavily on HTML5 video, Ogg/Theora, Zend Framework and jQuery and was an experimental research project of developers from the lab of Waag Society.
Annotrax was a further development of LooseControl in the field of video annotation. With Annotrax, users can participate in tagging videos. With the annotated videos, remixes can be made that result in new video material. Annotrax was complete built on open source software, and was itself offered again as open source software to build video archives.
Annotrax has been created by Waag Society and was partially funded by MultimediaN.
