Towards Collaborative Video Authoring

It’s a long time since video post production became digital, yet the issue of collaborative video authoring has not been seriously investigated so far. In this paper we tackle this problem from a transactional point of view, that allows us to ensure consistent exchange and sharing of information between authors by taking into account application semantics. Our main contribution is the development of a new data model called concurrent video, especially intended for cooperative authoring environments. We demonstrate that the presented model provides efficient means of organizing and manipulating video data, at the same time enabling direct use of merging mechanisms, which constitute a formal basis for collaborative scenarios. Moreover, since the proposed approach is mainly media-independent, we argue that the results of our work are applicable to other types of stream data as well.
