About

DCP-o-matic-combiner is a macOS application for preparing video, audio, and subtitles as a DCP (Digital Cinema Package), the standard format used by cinemas. The project describes DCP-o-matic as a tool for getting content ready for digital cinema, including films, festival submissions, and cinema adverts.

  • Converts video, audio, and subtitles into DCP.
  • The project identifies film-makers, projectionists, film festivals, subtitlists, and cinema technicians among its users.
  • This Homebrew cask installs the Combiner app, DCP-o-matic 2 Combiner.app.

Install with brew install --cask dcp-o-matic-combiner. After installation, open DCP-o-matic 2 Combiner from your Applications folder and use it to prepare content for digital cinema. This cask is specifically for the Combiner app; it does not establish that other DCP-o-matic applications or tools are included.
