Capturing VHS Subtitles?
 
Hello,

Is there a way to rip the subtitle from VHS source ? Most of guide I saw deals only with DVD source....is there anyone know how to achieve this ?

Thanks,
Dredj

You would need a machine capable of capturing the analog lines that carry the closed captions. My Panasonic DMR-E20 does that. It captures CCs perfectly. That's what I would do, because the subtitles on a VHS are embedded in the picture. Then after you have that captured to MPEG-2, you would need to extract the subs from the stream. I don't know exactly how to do the process, but probably using TMPEG "demux" tools, you'll see all the streams in the captured MPEG-2 file including CCs. So then it would be a matter of extracting the RAW CC stream and converting it to useable subs to be encoded. Check WinSubmux and other subs programs around. Hope this gives you some ideas :)

Thanks Kwag, I guess I don't have a luck as I don't have that machine. :cry:

Maybe with a capture card will do :idea:, but I'm not sure which could possibly capture CC :roll:
Here's some technical docs: http://msdn.microsoft.com/library/de...edcaptions.asp
Look at the end: "Capturing Closed Caption Bitmaps
Maybe using Microsoft's GraphEdit ( Docs and tutorials at doom9.org ) is the ticket :idea:
