Forty Vivitek laser projectors are at the heart of a 90-minute immersive audiovisual experience exploring the work of Wolfgang Amadeus Mozart at the Collège des Bernardins in Paris, installed across four spaces within the 13th-century Gothic venue by creative studio Cosmo AV.
The Mystery of Mozart, conceived by event producer Michel Eli, takes visitors through 16 of the composer’s works across four immersive spaces, combining music, dance, and video mapping across the Gothic architecture.
The installation uses two Vivitek models: the DU7299Z, offering up to 10,000 lumens and WUXGA resolution for the larger spaces, and the short-throw DU4381Z-ST, delivering 6,100 lumens, for more confined areas. All 40 projectors are remotely managed and synchronised via media servers, with a timecode system ensuring precise alignment between image, audio, and architectural transitions.
Cosmo AV – whose previous projects include video mapping for the Sochi Olympic ceremonies, and the reopening of Notre Dame de Paris – modelled the four spaces in 3D from floor to ceiling before designing each animation to the millimetre, accounting for lighting constraints, distortion curves, and projection angles.
Installation work was carried out in overnight slots between 10pm and 6am to avoid disrupting the venue’s weekday programme of concerts, conferences, and educational events. A custom IT network was developed to enable end-to-end remote management across all spaces.
Bruno Le Vacon, production director and technical integrator on the project, said: “It was essential that the organisation of the show should create as little disruption as possible. We created enclosures that blend into the décor to house the projectors and control consoles, while also ensuring the protection of the equipment.”
Pierre-Yves Toulot, founder and CEO of Cosmo AV, said: “We were looking for a single projector supplier capable of meeting all our installation constraints. Beyond the excellent price-to-performance ratio, Vivitek stood out for the precision of its optics, which simply did not exist among competitors at this level of quality.”
The show runs at weekends and during school holidays, requiring an installation that could operate fully automatically and be managed remotely without permanent on-site technicians.
