h3. What is GaliTracker ?

GaliTracker is a smart solution to transform dual-stream [Matterhorn|http://www.opencast.org/matterhorn] recordings into single-stream videos for their distribution to iTunesU, YouTube or mobile devices distribution. VGA and professor videos are "glued" together side by side. Thus, the video layout is optimized by dynamically cropping and zooming the professor video. GaliTracker guarantees plenty of room for the VGA video while the professor is always present in a smaller area, but large enough for the viewers to read non verbal communication, keep them engaged, etc.

GaliTracker Core is based on algorithms property of [Multimedia Technologies Research Group|http://atlanttic.uvigo.es/index.php?option=com_content&view=article&id=85%3Agtm&catid=45%3Agrupos-de-trabajo&Itemid=80&lang=es] \- University of Vigo.



h3. How does it Work ?

Professor video is recorded using a wideshot (not moving) HD camera. During the postprocesing of the recording, and without realtime restrictions, GaliTracker advanced algorithms track professor's face and the "Auto-Cameraman" module crops and zooms professor video automatically.

You will find several examples at the end of this page (videos could take some time to start on slow Internet connections)
