CST

What CST does

CST (Commission Supérieure Technique de l'Image et du Son) is the oldest association of cinema and audiovisual technicians in France, founded in 1944 and headquartered in Paris (9 rue Baudoin, 75013). Operating as an association loi 1901 non-profit, CST defines and disseminates technical standards for the French cinema industry through public Technical Recommendations (CST-RT series), free downloadable test patterns (Mires), the Label Excellence and Label Immersion certification programs for cinema theaters, and the European Cinema Preservation Package (CPP / EN 17650) standard for long-term digital archiving of cinematographic works. It also operates the open-source 3D-Info viewer and contributes to the Gaia-X-aligned TAMIS and TEMS European dataspace projects for media metadata exchange.

CST's core technology stack centers on standards development and domain-specific tooling rather than proprietary software products. The organization runs professional training programs covering ecological transition, accessibility, digital projection, virtual production, VR, eco-production, and VHSS (violences et harcèlements sexistes et sexuels) prevention, funded through AFDAS, employer DPC, France Travail, and CPF credits. It administers three award programs: the CST Award for Best Artist-Technicien (since 1951, previously the Vulcain Prize and Grand Prix Technique), the CST Award for Best Young Female Film Technician (created 2021), and the Jean Vivié Award for projectionists and editors (since 2001). CST has held official technical management responsibility for all Cannes Film Festival screenings since 1984, overseeing projectionists, technical teams, and service providers, and publishes La Lettre CST, a professional review issued three times per year.

CST's business model is membership-funded and partnership-driven. Revenue streams include annual membership dues from technicians, associations, and associate members (pricing undisclosed); training program fees eligible for AFDAS, DPC, and France Travail coverage; and certification/labeling fees from cinema exhibitors pursuing Label Excellence or Immersion distinction. The organization maintains strategic partnerships with CNC (Centre National du Cinéma), AFDAS, and standards bodies (AFNOR, ITU, ISO, SMPTE), and is supported through public funding channels including France 2030 for the DIACTIS skills diagnostic project. Distribution channels include the cst.fr membership portal, formation.cst.fr training platform, vod.cst.fr member VOD service, and prix.cst.fr awards platform. Operating geographies are concentrated in France with expanding European scope through the Gaia-X dataspace initiatives.
