How to extract subtitles from .ts file?

[vhwul62]

Looking for a user friendly tool that can extract subtitles from a .ts file.
I tried CCExtractor, TSDocter, SubTitleEdit but probably, or better... I am sure, I must be doing something wrong.
Am not an expert at all.

After hours of trying I gave up and ask here. No doubt folks here are experienced and know what to do/give me suggestions.

First the .ts file: please find details below.

I have added some screenshots of CCExtractor. As for the PDF file, click on the first screenshot, to display the other screenshots.
Maybe someone can tell me what I should tag.

Hope someone can help me.

Or maybe I should use some other tool?

Thanks.

In the last picture it looks like you were getting text. Was the text it was outputting wrong or something?

[HelpVid]

Open your .ts file with SubtitleEdit. It will automatically detect your sub, then you can OCR and save as .srt or convert as .sup etc.
Other method is to use ProjectX to extract them as .sub. It's a bit pain in the ass to configure but can do the job. Prefer SubtitleEdit first.

Thanks.

I did not check that, but it was -not- the text belonging to the documentary. I assume it belonged to either the commercials, etc. at the beginning or the stuff at the end. CCextractor only created 1 .srt.

Now, to get rid of confusion on that, I -just- removed the commercial at the beginning and the crap at the end (roughly 5-7 minutes) and am now re-encoding it to a .mkv file (TMPGEnc Video Mastering Works 6).

It'll take some time.

Maybe it will be easier then, meaning: just the actual documentary and a .mkv file.

Any suggestions how to easily extract the subtitles (also with CCExtractor?)

Tried that as well (Video->open).
It took a while and then it crashed

An application error occurred in Subtitle Edit 3.5.6.0.
Please report at

following information:

etc.etc.


Happened twice, so I gave up on that. Maybe the file was too large, a little over 10GB.

As written earlier, I am now re-encoding it and see what happens (or better: what comes out)

[HelpVid]

Yeah, large file can be a problem. You still try ProjectX. You'll have to select the ID of the sub (0xCFF or 0x80FC) and deactivate all other stream (not needed for sub extract). In preferences select export sub. Then it would be good. Maybe try a different color (still in preference).

[vhwul62]

Let's see what comes out, right now the encoding is at 60% now, the .mkv file is about 8.7GB.

[HelpVid]

I assume you'll loose any sub track after encode, right?

[johns0]

You don't need to re-encode a ts to mkv,thats just a container format,just load the ts into mkvmerge and output as mkv.

[HelpVid]

Mkvmerge doesn't support dvbsubtitle (at least the time I work on this it wasn't the case).

[johns0]

Have you tried the latest mkvmerge?From what i read last year DVB Subtitle support was being added.

[HelpVid]

Didn't know. Good to know.

[Melan]

I use both of the above applications.
CCE serves to extract subtitles that appear in teletext from the stream. Remember to enter teletext page number with subtitles (Decoders / Teletext decoder / Page for subtitles), because sometimes the program does not draw anything. Sometimes, I have to pass a .ts file through VideoRedo, because CCE throws a communique with "too big a file".
I also use Subtitle Edit (only for dvb subtitles). You have to remember to install Tesseract. Subtitles extracted using this method always contain errors. You need to configure the tools contained in the SE for yourself.

[vhwul62]

Thanks for all the replies folks! Really appreciated.
Now, I have the recordings in both formats:
a. the original .ts file (with commercials at the beginning and the end) - size 10GB
b. an encoded to .mkv file (commercials removed)

Subtitle Edit: opening the .ts file - crashes - twice - it takes verrry long to open the file, it hangs at 99% and then crashes - file probably too big
CCExtractor: using the .ts file - the only thing I managed is to get subtitles of a part that I don't need, but not the part I need

that is the status so far.

Remember: I am not an expert, far from that...

I downloaded and installed MKVToolNix 21.0 - at the end of the setup it says:

''
If you need a GUI for mkvextract then give these projects a try:

gMKVExtractGUI
MKVdeaver
''

I tried
Subtitle Edit with the .mkv file - no subtitles found
CCExtractor - tried various options, but frankly, I don't know exactly what option to use.. Anyway, nothing came out

mkvtoolnix: I have now launched mkvtoolnix and loaded the original .ts file

Got the below screen, but eh ... now what?

The 2nd screenshot shows when I load the .mkv file.

thanks.

[Melan]

Try to upload the .ts file to MKVToolnix, select only the tracks with subtitles and export them. Then put this extracted file into Subtitle Edit.
Have you checked if you have Tesseract-OCR in the Subtitle Edit folder?



Extracting subtitles using Subtitle Edit from a .ts file.

[vhwul62]

I selected the subtitle track only, but what do I have to click on next...??

I believe tesseract is available.

Thanks for helping me out....

[Melan]

Yes, "start multiplexing".

I have something like this:

[vhwul62]

Thanks.
I installed teseract latest version and copied it to Subtitle Edit (delete existing one)
Import video, but no subtitles

MKVTool - did multiplex - file created xyz.mks
Within Subtitle Edit import mks file - nothing
MKVToolNix export to .txt file - nothing

Well, I have spent many hours on this. Apparently it is too complicated for all the tools I used.
CCextractor, TSDoctor, ProjectX (don't know how that works) I let it rest, it seems to be very complicated.

Thanks anyway.

You could try to convert DVB subtitles to DVD subtitle format with ffmpeg - Teletext and DVB subtitles are two different things.

[vhwul62]

I think there is something peculiar with these subtitles.
I also tried idealshare using the original .ts file.
https://www.idealshare.net/video-converter/extract-subtitles-from-mkv-vob-avi-mp4.html

in my case subtitles are listed, but there are no [Save as] buttons.

when I use the .mkv file (removed commercials), there is no subtitle track, only audio/video, so
my guess is they are burned in.

[Melan]

All these unsuccessful attempts apply to the same .ts file?
Try to record other files from different TV channels.
If you can, put in a small sample of the file for hosting. I will see if something can be learned from it.

[HelpVid]

I was thinking the same. Please don't hesitate to share a small sample (made using mkvmerge or tsdoctor).

[Melan]

Check PM.

[HelpVid]

The one with Subtitle Edit in the title do have sub in it:

[Attachment 45016 - Click to enlarge]

Could you make a sample of your "bla bla_20180123_2245.ts" video as well?

[Melan]

You got two files. One with DVB subtitles - you opened it.
The second contains subtitles in the teletext - you must open it in CCExtractor.

https://forum.videohelp.com/images/imgfiles/qU0xnJK.png

Enter the page number of the teletext with subtitles - in this case it is 777, because on this page in Poland subtitles are broadcast.

I thought maybe you do not know exactly what to do?
Once you have achieved what you showed on the screens, press "Lancer OCR".
The OK button (on the right) is only pressed after "reading" the last line.
Set everything up like on the screenshot.

Many many thanks for the help so far. The teletext thing indeed was the solution. In my case I had to take 889.
Initially I tried 888 (which 'officially' is teletext here, but in the CCExtractor results it showed 'Notice: Teletext page with possible subtitles detected: 889'
So I tried that one and got the results now. Super!
Again many many thanks.

It is very 'precise' - I mean - one needs to know to select teletext and even the exact page, else, nothing.
There is no room for mistakes. No results for dummies like me..

Of course I have made screenshots of all the steps for 'future cases', should I need it again.

Truly appreciated your help!

Easiest method I've found is just upload the .ts file to YouTube. Make sure it's on a channel you don't care about copyright strikes and upload it to "private" setting. YouTube will automatically parse out the subtitle file and you can then download it.
