I Thought I Understood Sub-Titles

[johann1244]

Hi All,

I thought I understood what sub-titles were. I understood them to be those things you see during an entire movie that show what peopole are saying in "another" language.

I am wondering about what I came across today, however.

Just for practice I ripped the movie "I Spy", which I own, to see if I could generate a working SVCD.

I did and all seemed well.

There are only two points in the movie where an actor speaks a "different" language, as far as I know.

For those familiar, one point is at 18.5 minutes in, where a hotel room is ordered "in the basement", and the other point is at about 66 minutes in, where policemen come and arrest Mr. Murphy.

Both of these points were extremely brief, and had what appeared to be sub titles showing when the original DVD was played. But I wouldn't have considered them real sub titles in the true sense. They seemed to be right on the film itself.

On my practice SVCD, which came out beautifully - there were no words at the bottom of the screen at the two points I mentioned. I had great resolution and sound, and I tinkered it on to two 80 MIN CD's. But no sub titles.

Since the "sub titles" are only used at these two points, (as far as I can remember), I wouldn't think you'd have to rip separate sub titles.

Is that what I missed? Did I need to rip sub titles?

Has anyone else tried this particular movie and gotten the two sub titles I mentioned in? Anything similar?

TIA

Afraid that these catch many people out - usually because they rip the movie without first watching for the 'forced subs'. All it is is a seperate sub-stream that is 'forced on' during DVD playback - you do not usually have the option to turn them off in the DVD menu system (but can in a s/w DVD player)

You can spot them if you look at the substreams prior to ripping - they are usually listed after the main subs and usually in English - so just select this stream.

If you do a search on 'forced subs' you can get more info if you wish ...

Ok, I get the "forced subs" idea.

Now, I know I ripped EVERY sub stream from the DVD. Every file group I checked out looked fine, except for one. The one in question showed a single VOB file named T06P00_0.vob, which was 654Kb in size.

After CladXP auto-ran DVD2AVI, I also had a file named T06P00.d2v which was 1Kb in size and another file named "T06P00 AC3 T01 3_2ch 384Kbps 48KHz.wav" which was 1,189Kb in size.

After I encoded it to MPEG using TMPGEnc, I got a file name T06P00.mpg which was 1,115Kb in size. I batch encoded it along with all the other groups of files I ripped. Every single one works - plays fine audio and video - except for the one.

Of course I'm referring to the one mentioned above. It seemed to encode just fine. However, when I play it back, all I get is a few seconds of a blank video screen along with no audible audio. No flubs, pops or hisses - just blankness.

Is it possible that this is the sub stream containing the forced subs ? What would one look and sound like when extracted and encoded, then played back standalone ?

TIA

Please excuse any spelling errors. I have a muscle weakness illness.

A 'stream' is a series of multiplexed media 'types' across ALL VOBS. For example, one stream might be the video itself, another stream AC3 Audio, another stream might one subtitle.

eg

Vob1 Vob 2 Vob3
Video Stream ----------------------------------------
Audio Stream -----------------------------------------
Sub Stream 1 --- --- --- --- --- --- -- -
Sub Stream 2 -- (forced sub)

So in the above example - substream2 is only has 'data' in vob3 but it must be selected if you want the subtitle.

Also to note, as I assume you're encoding to SVCD, you need to ensure that you use a subtitler to do your subtitles - for forced subs, I suggest you just encode them permanently in the video.

Have you tried DVD2SVCD ? (www.dvd2svcd.org) - i does all this for you ...
