    I have this issue (well, I have many issues, but this one is the one I write _you_ about).

    I'm making a guide for ripping DVDs, turning them into CVDs (yes, China Video Disc, not VideoCD), burning them to CD, later on once we get cash, getting them from the CD, joining them back as one video stream and burning them to DVD-R.

    Ok, so far everything works perfectly, CVDs play nicely from CD when played with various players, like Pioneer. They also burn back to DVD-R and play nicely from there as well.

    The problem is what the topic states:

    -How do I demux subtitles from CVD/SVCD?
    -What authoring software allows subtitle imports and what formats do they support?
    -How do I convert the stuff what I get out from CVD to this format?

    Help me and you help AfterDawn to get one more guide :)

    As far as I know, you can't, unless those are hardware subs, if they are software subs, they are integrated into the movie, and I don't think it's possible to extract them, atleast not to my knowledge.

    What do you mean by hardware/software subs? AFAIK, there are two ways of getting subs into SVCD/CVD -- either by encoding them into the picture itself, when they become a part of the video itself or by making real CVD/SVCD subs that some players (such as most cheapo players and most Philips players) can play (but none of the existing PC video software can play). WinSubMux is the tool that does the muxing of the subtitle stream(s) into a CVD/SVCD stream -- DVD2SVCD package uses this tool as well. And those are the subs I would like to demux from the stream back to a format that can be converted into Maestro/etc subs.

    Ok, same meaning, different words used ;-)

    Encoding into the SVCD/VCD is what's called software subtitles, which means they are permenent and cannot be disabled, they become part of the image, and you can't extract them.

    Muxing them into the (S/C)VCD is what's called Hardware Subtitles, whic means they can be turned on and off by the player, like in a DVD Movie, those should have an ability to extract them.

    If you want, i'll check around for you on how to extract them and if it's possible, cause I believe it is.

    That would be cool. And obviously turning the extracted subs into some format that can be used directly or converted to some format that DVD authoring tools can understand, would be a bonus :)

    I put the guide online already and I'm spending way too much cigarettes figuring out a way to squeeze it into our database-driven system in order to get it to our search index, etc.

    You should do plain almost text-only version that wouldn't have _any_ <font>, etc tags -- only text, <img>s and <a>s in place :)

    But I'll get it "correctly online" within days when I get enough time to focus on it :)

    Oh boy are you gonna hate me for this ;-)

    You know, been ages since you "updated" the guide, your copy is now officialy old :-D

    If you still got the download link for it, I'd recommand using it, since the "version" of the guide you have, i've added: burnatonce / alcohol 120% and updated VirtualDub to 1.5.1 and VCDwizard to 2.7.0.0

    By the way, the guide looks good there, what is it exactly you are planning on doing in this "compression" ? as for re-doing it in text, well, i'm not one for self turture :-D

    Oh, if you don't have the download link, let me know, and i'll private message you for it!

    PS: Is the link you gave will be the official one ? I need to know, so I can add the link to the guides links page, not to mention my own homepage as well ;-)

    It is the official one. And the database adding is pretty important for us, to get it within our normal page layout which is required to get the navigational and advertising to the guide.

    But anyway, I'll figure out a way :)

    Why not use my title.htm file and add the advertisement to that section ? that way it will always be visible no matter what page will be picked from within the guide.

    PS, go to the private message, i've updated the guide since what you have online there ;-)

    Oh, any "commercial" on the web to say you are hosting my guides now ? ;-)

    I'll publish the news once I get it "up and running" in the way we prefer it to show, whatever the efforts are to make it "afterdawnized" :)

    Other problem, bigger actually, is that frameset/dynamic menus are a big turn-off for search engines -- the lifeline for all web publishers :)

    Hmmm... although I made sure that the guide will be easy to use without the menubar, I think it would be rather complicated to access a program directly without it :-/

    As for searches, i'm not really a web designer or anything, I don't know the faintest clue about HTML, I use Netscape 7.01's Composer to edit all the files :p

    That's ok and understandable. I think we should have a chat with Baldrick and suggest you a format for the guide in future as he runs a database-enabled site as well ;-)

    Hmmm... actually, if you take a look at the guide on DVDRhelp now days, you'd notice it isn't even remotly close to the guide you have from me ;-)

    That's mainly because he also doesn't really like the new design, actually so far he was the only host that hates it! cause he always has to re-do everything to fit it into how he wants it to look.

    Basicly, if you find an easier way, let me know, just as long as I don't need to write in codes :-D

    Like said -- I'm fairly certain that the easiest method for 99% of the sites (as pretty much everybody runs application servers, such as PHP or ColdFusion nowadays and don't have static HTML pages at all) would be for you to grab the pages to a text editor and make a "plain version" out of it as well -- leave just basic, basic tags like <p>, <br>, <a>, <li>, <ul> and <img> tags. Basically, get rid of the <font>, <html>, <body> tags and colours and keep the structure otherwise as it is.

    Hmm Hmm,.. allow me to show my ignorance and clarify how much of an idiot I am when it comes to HTML codes: I have absolutly no idea what all those mean! :p

    Basicly, converting the pages themselfs to plain text shouldn't be too easy, but then, what about the pictures ? the guide is 90% pictures and the text just explains them.

    PS: If you answer to this, i'll read it when I wake up, it's midnight over here, and i've had a rough day (health problems) so i'll be checking up on you tommorow! night night! :)

    NOTE: Don't forget to re-download the Guide! :p
