Broadcast Standalone Caption Files

• MCC (MacCaption Closed Caption)

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.
