My contribution presents two ongoing research project at INRIA on the theme of video analysis of theatre performances. The first project, Scenoptique investigates novel techniques for recording and analyzing ultra-high definition, allowing to reframe and edit the recordings into interactive movies. The second project, Spectacle En Ligne(s), is targeted on the creation and diffusion of an original data set of integral video recordings of theatre and opera rehearsals. The data set is naturally suited to researchers interested in the creation process and the genetic analysis of dramatic art and mise en scene. To support research in this area, the project proposes novel tools for recording, annotating, publishing and sharing the data. The project thus introduces dedicated annotation and indexing schemes suitable for both for online and offline use. The project also investigates how such data sets can be presented to the general public on the theatre web sites and social networks, and collaboratively enriched by personal annotations , comments and studies. The data sets and associated tools will be presented and distributed to interested researchers from all relevant fields in France and internationally as they become available. In such experimental work, high quality video recordings make it possible to track the audio-visual shape of the genetic evolution of the performance, which becomes an object of scientific study as well as an object of aesthestic appreciation.
