With CaptionMaker-NLE (Windows) you can caption any 720x486 uncompressed video sitting in your NLE system like FinalCut Pro Avid, Media 100, Adobe Premier etc. without using any external closed caption encoder. Then you can dump the video to a tape format (BetaSP, DigiBeta etc.) via the NLE hardware (like Avid
AJA, BlackMagic Decklink etc.)

To caption a video, you need the transcript of the video. There are many ways to transcribe a video. After obtaining the transcript, You will then import the script to the CPC software and format the script. Finally, you will listen to the video and synchronize the captions to the video by associating timecodes to
each caption manually CPC software then exports a 720x486 black video with closed caption data on row 0 or 1. Avid systems, for example, the caption data sits on Row 1 and column 26. The 720x486 video file is then imported into the NLE system and put on the time line along with the original video. A picture-in-picture effect or a crop effect is then applied to the imported video to mask off all but the closed caption image line to merge the imported video with your original video
