Why capturing with CC (Closed Caption) is a secret?!!

[dominic01]

Is it really not possible to capture with caption or is it a Secret?

What do you mean by "capture with CC"?

If you want CC to be displayed, run the tape through TV with CC on and capture it. If you want to transfer CC to subtitles or DVD with CC, I think there are tools to do it, but I am too lazy to do it.

The terms "Closed Caption" and "subtitle" confuse me. I think you are talking about smartripper. Let me try that.

Actually I wanted to capture some TV programs with closed caption and burn them into a DVD (sometimes VCD)

So why don't you do that? Works for me. I did it with my dvd recorder, also ATI all in wonder cards do this. They can even record the captions to a WORD document.

Subtitles refers to text muxed in with a DVD, VCD, DiVX etc. These are readily extractable, trasferable, added in etc. Close Caption is a video overlay (I think Line 21 or something like that). I've looked for some time to find a tool that will extract it. There are a few things out there, but noting I would remotely consider easy. (Graphedit filter, OCR, Subtitle editor capbable of creating a new subtitle file is the basic process). It appears to me that the subtitles are present in an AVI capture, then lost in the encoding to MPEG.

There are two work arounds. One is as previously suggested, turn close caption on and capture that. That does give you closed captions, but they are permanent. Plus, not all systems are capable of turning closed captions on, remember that's a property of the receiver not the player like subtitles. Typically an analog TV card capture device can do it, a DV pass through device cannot. The other work around I came up with was I found a few libraries of subtitles at one of the DiVX sites (I forget which one). You can down load those then use one of the various programs to add them into your encoded video. I stopped messing with it for two reasons, first I didn't find subtitle files for movies I was encoding very often and second, it was a major pain to try and syc up the subtitles to the movie.

Good luck with your hunt and post if you find any more information. There used to be several of us looking.

Just read the last bit of Handyguys post. That would be huge (assuming you are using an ATI capture card ) Does the Word doc have timecodes? That's an important piece.

[SLK001]

Most capture cards only capture the video (which would naturally skip over the CCs on line 21 of an NTSC signal).

Using the GRAPHEDIT DirectDraw filters is the only way I know to strip CCs off a ripped DVD (done it more than a few times, myself). McPoodle has written some tools to convert this CC raw data into readable text, and into a .SCC file, which is what is imported into DVD programs that support CCs. I don't think that these tools are here, but look in DOOM9.NET for these (or get them from his website).

CCs are added to the encoded video during the DVD compiling process.

Does the Word doc have timecodes?

Nope. The transcribing feature, called TV Magazine, is basically intended to transcribe a show. It just puts the captioning into text. Besides the ability to have it automatically snap images from the video and insert them.

The only way I know of to make that CC info usable on DVD is to cut & paste the text from the text file and insert it with a subtitle program, or if your DVD authoring program supports it, then to use that. The only thing is that you have to set the timecode for the subtitles. This is why I don't bother adding subtitles to my DVDs (I've been saving some of my transcripts in text files just in case I decide to redo those shows later with subtitles).

Currently I am using Leadtec TV2000XP Dlx card.

I think this card doesnt have the capability to capture CC (or I may be doing something wrong). But when I watch TV programs on my syatem I can turn ON the CC through the Winfast PVR software.

When I was searching for a new driver for my card I came across a driver with "Teletext support". Could someone tell me what is a teletext? or is it another term for CC.

TeleText is used in countries that use the PAL broadcast system. North America doesn't use TeleText and UK, Australia, etc don't use Closed Caption.

In other words, they're two different standards.

unless they mean Teleprompter -- which means the text is reversed (its shown off a mirror)

[handyguy]

I have one of the early captioning boxes, a Telecaption II decoder. It has a selection to output CC video. So, if you record the output the copy has open captions on it. In effect, it has converted the closed captions to subtitles automatically.

The only problem with that is that the captions are burned into the video, so there's no way to get rid of them.

I am also using Leadtek TV2000XP Deluxe. I think you're right, when I capture video into an mpeg file and try to extract CCs afterwards, i get the the message that the file has no captions.

The card supports displaying CCs though. These can be captured using graphedit. I've done it with several VHS captures.

If we are talking about closed captions that are displayed with TV programs and such, any ATI AIW card will be able to capture the CC text and save it to a text file. Now is it just plain text (no timing info) and it is all in caps. However it can be done within ATI MMC.

It's so funy that america doesn't have teletext

I think teletext is just something they built on the CC technology... (it's another example on how america created something and how they didn't refine it)

when you push the teletext button here you get a mnu, you can enter which page you want to go at and all, and on most stations there is also a kind of 'closed captions' ... The only thing that happens is that the black screen becomes transparent and you only see the words and all, just like CC...

The shame with closed captions in MPEG is that most decoders (Intervideo & Cyberlink included) do not support playing back closed captions in MPEG files, unless it's a DVD.
