![]() ![]() Someone (I don't have a link handy) has created a little tool to capture the closed captioning data under Linux, since any Video4Linux 2 capture device that supports VBI data (almost all of them your should be supported under the bttv driver) dumps it raw to the /dev/vbi device. It is relatively cheap for what it is (excellent hardware MPEG-2 encoding capture card, lowest price I've seen is CDN$187.50) With a registry hack, you can get it to record the line 21 data, which can then be converted to a text subtitle file which you can then use DVD authoring program to turn into selectable DVD subtitles. There isn't an easy solution to this - most cards, while able to decode the captions, do not offer a way (in their software) to save them with timecodes. Problem is, capture cards only capture the 480-486 that have the image in it (the rest is for vertical blanking information, captioning, XDS data, etc.). I would appreciate knowing if I'm trying to do the impossible or if there is some other software or process that will work with this card and give me a dvd that works and has cc.Īs you are probably aware, closed captioning data is on Line 21 of the 525 lines in an NTSC image. i also notice that none of the codecs in the PVR show a closed caption option. I do not see them when i replay the created file through the PVR. When I play the tape through the Winfast video player I see the captions. Also my dvd player is set to show closed captions. ![]() I know that the tapes I used have closed captions because I see them when played on TV. I am partially deaf and using the Leadtek PVR or Roxio 7 Media Creator to capture the video i cannot get closed captions (I used Roxio to make the DVD from the MPEGII file). Since then I have been able to take VHS tapes from my vcr and get MPEGII with no problems-quality is very good. i used the new drivers and PVR programs from Leadtek's site and was able to install them with no trouble. Recently i installed a Leadtek Winfast TV2000 XP Deluxe card. ![]()
