Closed Captions on DVD
I’ve read all the posts on closed captioning, but can’t find what I need. I have five videos that need to be compiled and delivered on one DVD with closed captioning. CaptionMax, who usually does my cc work on videotape, says they can deliver me five .cc or .scc files with the pre-timed captions ready for Line 21. My question is: Can these .cc files be imported into Avid DVD by Sonic and work as true “closed captioning” and not just as “subtitles,” which the client will not accept. (In other words, the closed captioning has to be switched on or off with the TV settings, rather than on the DVD menu– which actually doesn’t even come up on screen until after the first 5:00-minute introductory video plays.)
All I’m seeing in the Avid DVD Help screens is subtitle info, which is making me think that this is not going to work the way I need it to. Does anyone know for sure if this will work, before I spend the time and money to try it? If it won’t work, does anyone have any other suggestions as to how I can do this without having to re-import the five complete cc’d videos via the Mojo and going down more generations? In case it matters, the raw video for all these shows was imported at DV25.
Thanks for any help you could provide.

I can’t honestly think if any of our DVDs have been checked to see it the captioning comes across on it. But I think you may be over thinking this.
If it was me, I would take a 2 min section of an old master on tape, with captioning already embedded, mpeg it, and burn it to dvd with no special settings. Play it back on a tv and turn on captioning, to see it it still comes across. The only question is whether the mpeg compression will bugger up the captioning. It works on VHS, so It might work on DVD. Either way, shouldn’t cost too much money or time.After that, just get the captioning house to make you a CC’d master as you have done in the past, and proceed as though the captioning wasn’t even part of the process.

I don’t believe it does. It would have to specifically support the import of .SCC files.
Sonic’s top end Scenarist authoring package does. Adobe’s Encore 2.0 does and Apple’s DVD Studio Pro software does.CC data is contained in vertical blanking area of the video signal on line 21. MPEG compression will eliminate CC data unless it is preserved prior to compression. If it is preseved a separate captioning file is created which can then be added back in. Some applications, like Canopus’ Procoder software can preserve the caption data if the original source contains it. Since DV25 is also compressed, I believe that that line 21 data will be gone as well.
