Problem with extracting subs from .ts

[Scotter]

Hello,

I can't seem to extract subs from this .ts TV recording. I've used ProjectX. Here's the file info:



And here, the settings I used:



Neither DVB subtitles nor teletext ones are extracted.

Could you please help me find out what the problem might be?

Many thanks.

I would suggest you post the ProjectX log file - tick all the boxes under the menu item Messages on the Process window. What you have shown seems OK assuming the teletext page numbers are correct.

Thank you for your response.

By the way, does Teletext and Subpict. PID's indicate the presence of subtitles streams in the .ts file, please?

[Moontrash]

to get subs from an .ts file you can use MeGui.

run it...click on "tools"...HD Streams Extractor...select the folder of file where the .ts file is....select a destination where you wanna save it...it will scan the file and at the bottom it will show you whats inside the .ts file....uncheck all the things you don't want to keep and click "Queue" and it will save it to the folder or place you specified

[Scotter]

Many thanks.

MeGUI shows only two types of stream, Video & Audio. Does that mean the .ts file doesn't contain any subtitle streams, even though ProjectX lists their PID's?

[Selur]

no it just means that MeGui can't handle DVB subtitles,... ever thought about iirc. http://ccextractor.sourceforge.net/ was able to extract such subtitles,.. (wasn't Project X also able to extract these to .sub?)

ccextractorGUI cannot do anything with DVB subtitles. ccextractorGUI is only able to work with NTSC DVD closed captions, or ATSC closed captions. Only DVD and ATSC EIA 608 closed captions really work. Adding support for ATSC EIA 708 closed captions is still in development. The program description says teletext, too, but DVB subtitles can be subpic-based or text-based, and from what I understand the text-based ones are not the same as teletext.

[netmask56]

You are using 'Demux' so if subs are present they should be there. However there is a reference to 'filter' on one of the folders - what is that exactly?

Maybe you could try an earlier version of PX ProjectX-v0.90.04.00.b29-20090221 as it is quite stable.

Can you read subs if you play the TS file in VLC?

[poisondeathray]

you can try dvbtextsub as well

[markwong]

I used ProjectX to demux many .ts files recorded from HD digital recorder. In my experience, some programmes will have subtitles hardcoded. That means it does not always contain separate subtitle inside .ts file. It is the problem about the source, i.e. it depends on whether the TV station provides you a hardcoded subtitle or separate subtitle. You can check it by trying to turn off the subtitle using the remote control for your TV or digital recorder.

[netmask56]

On the subtitles presetting page try unticking the first 2 options

[intracube]

ProjectX might be mislabelling the 0x0E12 stream as subtitle data. WSS in a broadcast context could be Widescreen Signalling: http://en.wikipedia.org/wiki/Widescreen_signaling

Usually this data is embedded in the video stream but perhaps it's also being transmitted separately?

[Budman1]

If the subtitles are truly DVB or teletext You can use ProjectX with the presettings as follows:


It saves several files and the DVB to .Sup (Teletext to .sup.sub)


Then open Subtitle Edit and drop the video.sup into it and click yes if it asks to import the vob file. When the OCR screen opens,
select the language (download additional if needed) and adjust the colors for white letters with black borders and background:


Click start OCR and it works fairly well. Save to whatever format you choose from the main page. Hope that helps, it has always worked well for me in the past.
