It contains native CEA-708/608 encoded caption data as well as OP-47 Teletext. It supports various features like multiple caption streams, positioning, styling, and other advanced settings. MCC files are often used in broadcast workflows and are compatible with a wide range of professional video editing and playout systems.
  • SCC (Scenarist Closed Caption)
    A universal standard used for Line 21 broadcast closed captions and the closed caption file format commonly used in the broadcasting industry, particularly for television programs.

  • CAP (Cheetah Advanced Subtitling Protocol)
    CAP files are typically used in professional broadcast environments and are compatible with Cheetah's closed captioning software solutions.
