CCExtractor – another way to extract closed captioning from MPEG-2 files

April 29, 2007 9:41 pm

I got a comment on my blog from the author of a free, GPL licensed closed caption tool called CC Extractor.

This software looks promising, even if I haven’t had a chance to test this yet! If you are able to directly record TV shows on your computer as MPEG2 files, the files may also store the closed captioning data. You could use this open source program to extract the closed captioned text and put them into a subtitle file.  You could start up a program like AutoGK and use the subtitle file to create a DIVX movie file of the TV show with hard subtitles (directly burnt onto the clip). 

My main problem is this:  Which devices/TV tuner cards can I use to capture the TV shows into a MPEG-2 file while retaining the closed captioning text?  This is the $64,000 question that I haven’t been able to satisfactorily answer yet.

    Wintv PVR cards can also capture MPEG2 streams with closed captions.

    This setup is known to work perfectly with ccextractor:

    "I use my Shuttle SN95V3's onboard firewire (ieee 1394) port (4-pin to 4-pin) to capture from my Comcast's Motorola DCT-6200 series HDTV tuner. i can only capture non 5c encryption channels like PBS, CBS, ABC, NBC, FOX, CW, etc. i use capvhs.exe and the drivers linked from avsforum."

    I hope this info helps.
  • Wow, if this is true, this is the last (I hope!) remaining step I need to get subtitles from HD TV to DVD (or QuickTime or Flash CS3)!

    On a Mac, using eyeTV from ElGato Sytems (http://www.elgato.com/) pulls the captions along with the program when you save it to a hard disk. I think Pinnacle has similar hardware (not sure about software) on Windows.
