With CaptionMaker-NLE (Windows) and MacCaption-NLE or DTV (Mac), you can closed caption any 720x486 uncompressed video sitting in your NLE system like Final Cut Pro, Avid, Media 100, Adobe
Premiere, 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, Matrox, etc.).
To closed 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 closed captions to the video by associating timecodes to each closed caption manually.

CPC software then exports a 720x486 black video with closed caption data on row 0 or 1. Avid systems, for example, the closed 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 or 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.
