Telestream software 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.
CaptionMaker and MacCaption can embed closed captions directly into many kinds of video files for digital delivery:
MacCaption can create alpha channel subtitle videos to overlay burned-in subtitles for any NLE system.
CaptionMaker and MacCaption can encode closed captions directly into DV QuickTime files. You can then print to DV (miniDV, DVCAM, DVCPRO) tape via Firewire using any version of Premiere Pro.
CaptionMaker and MacCaption can add closed captions to any kind of web video format: Flash, QuickTime (including for iPod/iPhone/iPad/etc.), iTunes, YouTube, Windows Media.
CaptionMaker and MacCaption can add closed captions and subtitles to DVD, Blu-ray, and most professional authoring programs.
