Example

Let's say we have two subtitle files

sub1.srt

1
00:00:41,666 --> 00:00:44,793
I've got the vibes. This thing is evil, man.

2
00:00:44,878 --> 00:00:47,171
I got a bad feeling.

3
00:00:47,297 --> 00:00:48,422
Shut up and keep moving.

sub2.srt

1
00:01:04,320 --> 00:01:05,990
Please.

2
00:01:06,260 --> 00:01:08,060
Please don't hurt me.

Code

import {merge, Subtitle} from '@lordofmax/subtitle-merger'

const sub1 = new Subtitle('sub1.srt', 90000); // The video duration is 90 seconds
const sub2 = new Subtitle('sub2.srt', 90000); // The video duration is 90 seconds

merge('output-sub.srt', sub1, sub2);

Results in output-sub.srt
