Don't be silly, Gran Mother

3
00:00:14,870 --> 00:00:16,700
Everybody knows there's no such thing as

4
00:00:16,700 --> 00:00:17,200
Mermaids

5
00:00:17,620 --> 00:00:21,570
You wouldn't say that if you has meet one. You've meet a Mermaid

6
00:00:24,250 --> 00:00:25,180
This just came in

7
00:00:25,480 --> 00:00:26,630
I wanted to take priority

8
00:00:27,180 --> 00:00:28,500

Welcome to Mississippi

12
00:00:42,390 --> 00:00:47,270
There's a powerful magic in you the spirit of the ocean

13

Let me introduce you to your dreams, The Little Mermaid, off the Mississippi

14
00:01:01,880 --> 00:01:03,580
She was so beautiful

15
00:01:04,040 --> 00:01:05,270
And I know she was real

16
00:01:07,850 --> 00:01:08,550
I'm skeptical

17
00:01:13,460 --> 00:01:14,410
You shouldn't be here

18
00:01:17,560 --> 00:01:24,130
Mermaids do not exist

19
00:01:31,420 --> 00:01:34,300
Look isn't it beautiful? Sorry I have to go.

20
00:01:35,340 --> 00:01:48,570
Elizabeth, How can this be? It's Lock he knows i'm here he summoned me.

21
00:01:48,570 --> 00:01:50,570
We have to save here.

22
00:02:03,570 --> 00:02:05,570
Here soul is mine

23
00:02:05,570 --> 00:02:06,570
Take it

24
00:02:10,570 --> 00:02:12,570
It's the only way

25
00:02:15,000 --> 00:02:17,570
I believe

26
00:02:23,000 --> 00:02:25,570
Mississippi has always been magic

27
00:02:36,000 --> 00:02:38,000

    I am trying to replicate this with FFMpeg. I have tried the following command.

    



    ffmpeg -i little-mermaid.mov -i little-mermaid.srt -c copy -c:s webvtt -start_number 0 -hls_time 10000 -f hls mermaid/Eng/master.m3u8


    



    This creates a WebVTT file but it is completely wrong and out of sync. See below.

    



    All the times have changed and it's removed the first two digits from each section.

    I am trying to decide if it just makes sense to convert the .srt to WebVTT and use that file without encoding with FFMPEG just create a .m3u8 file with -hls_flag single_file that points to it but not sure what implementation this might cause.

    



    Can anyone suggest how I could do this or where I might be going wrong ?

    



    Here is the video file I am using if anyone wants to run the FFMPEG command above to test.
