Capturing Closed Caption into text files?

[Maxiuca]

Hi,

I was wondering if there is any software (or hardware) tool that allows capturing closed captions into text files (with time code)?

I know that some programs allow closed caption to be shown on screen, but I haven't noticed any that would allow saving to text files.

I'm backing my collection of Laserdisc up and this is the last thing I need to make 1:1 copies.

I have TV Capture Card with Connexant chip.

Best Regards,

Maxiuca

I've been wondering this myself. I've seen quite a few channels on IRC pop up which have bots echoing closed captions of the war coverage on networks like CNN, FOX, etc. There must be a way :)

bt8x8 hardware (now conexant) does have
on-die support to decode CC,but don't know
if someone made a util that will
take advantage of this.....
dscaler has this option,but i doubt it can capture it to
txt file......
(although over here in europe it's not a problem to
capture (in a number of way) "teletext" signals,but
this is not quite the same...ttx is like electronic newspapers on tv(although ttx CAN be used to do subtitles too!)..

as far as i know
CC is sort of text description for deaf folks...
like subtitles...
interesting to note:some satv stations over here have "audio description" for blind people...everything is described by
a speaker....)
i asked myself same question,but as i'm not in usa,it's not
all that interesting

anyhow...here's what google
says(note that avermedia ezcapture software seems to be able):

hope you find a way.....
cheers

There is a VirtualDub plugin that does "capture" the unremovable subtitles from a video file to a text file... Sadly, I don't remember it's name or where I read it...

Try Donald Graft's site (neuron2)...

I know that the closed captions (amongst other things) are sent via the last few of 525 (NTSC) lines of video, not visible.

From your post, I get the impression that you believe the captions are actually captured along with the video stream. This is interesting, but it doesn't quite make sense to me. I think I will do some further investigation.

yes,no point in capturing subtitles to a txt file
if they are already in the video.......

it would serve some purpose if the
original inprinted subs could be easy removable from
the video but that's impossible......

[dilly]

How is it impossible, if there are programs that can actively decode it for display purposes? Surely, output to a text file wouldn't be impossible... and why couldn't a DVD plugin (note: my lack of experience in the DVD realm - I don't even own a player) like VobSub work to put the captions up at the right times?

Not something needed necessarily, but possible nonetheless.

dilly,read it again;
i said

>original inprinted subs

and i ment the subtitles that are a part of
the video itself (i didn't thought of CC)
have you ever rented a foreign movie vhs tape that had
subtitles?
that's what i was thinking of...
can't remove those....

the CC subs are not quite "inprinted" but
sort of
overlayed on top of video....

Maxiuca,

If your looking to extract out the closed captions that aren't "burned" into the video, you can do a search on the forum for filter graph information about extracting the raw CC stream from the data stream.

Once you obtain the raw data you can then run it through some programs to convert it to SRT.
