DVB or T.140

[JanJ]

When converting and wanting to add a subtitle, VLC gives the option to choose between Dvb or T.140 in the tools menu just before starting the conversion.
I cant find any info in the wiki or this forum on what these two options defines.

What does the choice affect?

Thanks!!

DVB is the standard for digital TV, and suited for MPEG Transport Stream. T.140 is plain text and mostly meant for "native" RTP transport.

Thanks Remi - I take it, then, that one should just choose Dvb as standard when creating mpeg4`s for dvd burning.

Neither DVB nor T.140 will work for DVDs. DVDs have a proprietary bitmap subtitle format.

SO how do you add subtitles to an avi? Do you use DVB or T.140? the subtitle file is srt.

It plays perfect just playing the movie and sub file. But can add subs by converting or just try to add sub.

Not trying to hijack just this is the closets thing I could find on subject.

If T.140 is the plain text subtitle format,
then I would like to USE it.

So I've tried every kind of "text format" or T.140 Format:
hh:mm:ss:[some line]
----------OR-----------------------
hh:mm:ss=[some line]
----------OR-----------------------
hh:mm:ss,1=[some line]
hh:mm:ss,2=[some other line]

and put them into the "media / convert+save / use subtitle-file dialog.

The resulting file does not show the subtitles.

Even if you tweak the profile settings, where there is another "subtitle" tab...

The resulting file does not show the subtitles.

I've searched the internet to find specifics on - yesss - the "T.140" format - but no way.

hmm - it just does not seem to work.

I wanted to publish a successs message

I succeeded rendering subtitles into an OGG-Theora-Vorbis Video.

The tweaks were
- use a SRT subtitle file ( identical filename neccessary ? )
- switch "show more options" on and off again ( ridiculous, but successful )

in "convert" dialog
- edit profile: tab "subtitle" - check subtitle, select "dvb subtitle" - check the last checkbox [show subtitles in video]
- edit profile: other tabs: I chose Ogg/Ogm container, theora video, vorbis audio
- show output switched to ON

And: I ended VLC before the streaming-filesaving was completed.

Of course not all these steps may be required,
but it was my "winning deck".

Regards to the VideoLAN Team.

And P.S.
My test demonstrates, that VideoLAN is capable of producing completely licence free Video-Audio Files (ogg-theora-vorbis)
from almost any input, and even rendering subtitles into the file.

It is therefore a perfect tool to produce "flash free" video material for viewing directly with firefox <video...> tags...

T.140 is for streaming (RTP), not for recording to file.

Easy way to add Subs "hard" to encoding (convert) file.

1.- Open (advanced)
- Add video file
- Add subs file - "use a sub..."
- Add audio file - "show more op..."
2.- Convert
- Search destination
- Choose preset
3.- Edit Options
- Choose encapsul.
- Choose video codec and rates
- Choose audio codec and rates
- Choose subs and overlay [don't DVB or T.140]
- Save
4.- START

hey Xabier Aramendi, you mean:
1. Go to File>Advanced Open File. Then under File tab,
-add video file.
-Then add subtitle file (.srt file will work)
-Then, for me, there is no audio file to add, it already plays in the video file?

-Then, do i tick the Stream/Saving box at the bottom of that window and do options there, too? or just click Open and proceed to step 2? When i click Open, the movie plays with subtitles, but, to be clear i want them to be merged as one file.

2. Convert. Go to File>Convert/Stream. A window comes up where i must add a video file (again) then

3. There is a window where i can choose a profile and then i hit the customize button next to it and get to
-choose encapsul.
-choose video codec and rates
-choose subs and overlay, and i dont select dvb or t.140
-Save

I don't have to wait long at all which is great.

At the end, i get a warning:
The output file already exists. If recording continues, the file will be overridden and its content will be lost.
i click 'keep existing file' instead of 'overwrite', and the same window just comes right back up with the same question for infinity, so i force quit VLC.

The video file is where its supposed to be, the video is fine, but no sound and no subtitles. I'm going to try OGG THeoris VOrbis i guess? what am i missing?

i used a whole different app (which i hate adding apps) 'ffmpegx' is a classic converter app and it was super easy.

On the post topic, i would pick dvb for this question, no doubt.
