Ripping subtitles from medici.tv as .srt

[pedrothelion]

Hello

I downloaded a documentary from medici.tv with youtube-dl GUI and it worked well.

Now I'm trying to rip subtitles from the same docu (they are splitted into many .webvtt segments) using Firefox and activate developer mode to inspect element. Then head to Network tab to find and search for: 'subtitles' or 'm3u8'.

What I get is a file of about 70 KB with .mp4 container.
I opened the file with notepad and this is the (partial) content:

WEBVTT

00:00:00.000 --> 00:00:04.280
Le piano est un instrument
plutôt neutre.
X-TIMESTAMP-MAP=MPEGTS:2415600,LOCAL:00:00:00.000

then I renamed the file as .vtt and converted it as .srt with Subtitle Edit.
What i get is a file like this:

The result does not seem to be a correct .srt file. In fact, combined with video, timestamps are busted, completely useless and out of sync.

Am I wrong in converting from .vtt to .srt or should I look for a different key with the developer tool?

[LZAA]

Url?

[sysanin]

LZAA это то же самое, что и здесь

[pedrothelion]

Url?

not resolved

[sneaker]

I guess this should be simple to fix using regular expressions.
Find:

^(WEBVTT|X-TIMESTAMP-MAP.*)(\r\n|\r|\n)

and replace by nothing.
Editors like Notepad++ and SublimeText offer such Search and Replace (All) feature with regex.

[pedrothelion]

But timing problem remains. It does not seem regular as expression...

[sneaker]

Sorry, I didn't see the timing problem. Indeed, that seems to be the complicated part.

I'm wondering if it is even possible to reconstruct the correct timings from just the info you posted.
Does the following fit the video?

1
00:00:00.000 --> 00:00:04.280
Le piano est un instrument
plutôt neutre.

2
00:00:26.840 --> 00:00:30.279
Mais il a des possibilités illimitées
de se transformer.

3
00:00:32.679 --> 00:00:38.759
C'est ainsi qu'il peut devenir
un instrument chantant...

4
00:00:47.36 --> 00:00:49.880
De voir que cet instrument

5
00:00:50.520 --> 00:00:53.560

6
00:00:53.560 --> 00:00:58.320

7

à ce que vous cherchez,

8
00:01:02.039 --> 00:01:05.039
est quelque chose d'extraordinaire,

9
00:01:05.039 --> 00:01:08.919
la raison pour laquelle je suis,
encore aujourd'hui,

10
00:01:08.919 --> 00:01:10.960
heureux d'être pianiste.

Nope... it should be like this:

WEBVTT

1
00:00:22.020 --> 00:00:27.004
The piano is finally
a rather neutral instrument.

2
00:00:27.008 --> 00:00:31.018
But it has a limitless ability
to transform itself.

3
00:00:31.022 --> 00:00:35.005
Thus, it can become

4
00:00:37.003 --> 00:00:39.003
a singing instrument...

5
00:00:47.017 --> 00:00:50.001
To see how this instrument

6
00:00:50.005 --> 00:00:53.018
actually reacts,

7
00:00:53.022 --> 00:00:58.013
and yields
to whatever you want to do,

8
00:00:59.010 --> 00:01:02.001
to what you are after,

9
00:01:02.005 --> 00:01:05.012
is something quite extraordinary.

10
00:01:05.016 --> 00:01:09.005
This is why I still am,

11
00:01:09.009 --> 00:01:11.003
so happy to be a pianist.

I can provide access if needed.

I probably won't be able to help. I cannot even manually get from the quotes in post #1 to the file from post #8, let alone in an automated way. I think it's not possible but you need more data.

Thanks for your reply. I finally succeeded with Allavsoft
I will also try with URL Snooper.
