Track4K in production

Stephen Marquard

Track4K ( is an open-source video analysis and tracking system that post-processes a 4K video to track the presenter and generate a cropped version of the video.

Track4K was developed as a student project at the University of Cape Town in 2016, and deployed as part of UCT's Opencast system in late 2017.

This presentation will give a short overview of Track4K, how it works, the integration with an Opencast workflow using the Execute Service, some results and limitations, and further research work currently underway.
