A complete HD closed captioning and subtitling solution.

No additional captioning hardware required. No generation loss.

CaptionMaker creates HD closed captions files for users of Avid Media Composer 5, Symphony 5, and Newscutter 9, or later versions. You can create an Avid AAF file using CaptionMaker, and any AAF file can be used on either PC or Mac based Avid systems.

See our product comparison chart to find the configuration that’s right for you.

How it Works


CaptionMaker generates an Avid-native AAF file that contains HD closed captions formatted for Avid Media Composer. This file is simply dropped onto the "D Track" or data track. When you play the HD sequence out through your Avid Mojo DX or Nitris DX hardware, or export a MXF or AAF file from Media Composer, the output will contain the closed captions. Our software can also generate a line 21 overlay file used to add closed captions to SD video sequences.

File-based Closed Captioning Workflows

CaptionMaker can embed closed captions directly into many kinds of video files for digital delivery:

  • QuickTime:
    • Line 21 onto any QuickTime video
    • QuickTime 608 SD Closed Captions
    • QuickTime DTV 608/708 HD Closed Captions
  • MPEG-2 Elementary, Program, and Transport Streams
  • MXF Files for XDCAM, Omneon and SeaChange servers
  • DVCPRO HD QuickTime files for Omneon servers and more
  • Common closed caption formatted files such as Cheetah CAP, SCC, MCC, etc.


CaptionMaker can create alpha channel subtitle videos to overlay burned-in subtitles for any NLE system.
