  • Preserving Closed Captions with Compressor

    I have a tape with closed caption info embedded in line 21. After being digitized, it’s still there, but when I use Compressor 3 to encode it for DVD Studio Pro, it chops off this info. Does anyone know how to maintain embedded closed caption information when encoding for DVD Studio Pro? Thanks.

    Kenny,

    I have never tried passing video through to DVD that already has the CC info on line 21. I’m not sure if this workflow should work or not.

    Anytime I go to DVD with Closed Captions I embed the .scc file with the video track. The .scc file has to be synced with the timecode of the video track and then it works perfectly.

    I have never used it and don’t know anyone that has, but you might look at CCExtractor (https://ccextractor.sourceforge.net) as it might be able to help you separate the video and CC.

    If you find a way to make this work, I’d love to hear what you find to make it work!

    Matt

    This is covered on page 83 of the compressor 3 user manual and is achieved through the use of a .scc file. As pointed out by Matt, CCExtractor should work fine for you.
