As we all know, .srt is one kind of text subtitle file, which is the most popular and frequently used. In fact, SRT file is a simple text file and its content looks like this:

1
00:01:00,000 --> 00:01:05,000
First sentence.

2
00:01:15,000 --> 00:01:20,000
Second sentence.

3
...

The format is simple and straightforward. The file is consisted of several blocks separated by empty line, and each block contains 3 lines. In each block, the first line is a number begin from 1 and increase by 1 each time. The second line is the show and hide time of the subtitle. The third line is the text of the subtitle. So, you can write such a subtitle file by yourself easily.
