Java program that formats captions written in a single line into proper SRT (SubRip Subtitle) files. Written by Jefferson Yu.
According to docs.fileformat.com, each subtitle entry in an SRT should be formatted with the following items:
- A numeric counter indicating the number or position of the subtitle.
- Start and end time of the subtitle separated by --> characters
- Subtitle text in one or more lines.
- A blank line indicating the end of the subtitle.
For example:
1
00:05:00,400 --> 00:05:15,300
This is an example of
a subtitle.
2
00:05:16,400 --> 00:05:25,300
This is an example of
a subtitle - 2nd subtitle.
Unfortunately, many subtitles are exported incorrectly as single lines. For example, the following subtitles were exported from one of my middle school Spanish projects:
1 00:00:06,080 --> 00:00:06,780 ¡Buenas tardes! 2 00:00:06,780 --> 00:00:07,560 Buenas tardes. 3 00:00:07,920 --> 00:00:10,480 Yo necesito una mesa y un menu. 4 00:00:10,900 --> 00:00:13,340 ¡Si! ¿Usted tiene una reservación? 5 00:00:13,888 --> 00:00:15,888 No, no tengo una reservación. 6 00:00:15,888 --> 00:00:16,923 Si. 7 00:00:18,260 --> 00:00:21,920 Yo necesito una mesa para una persona. 8 00:00:24,724 --> 00:00:26,724 Sientense por favor. 9 00:00:26,724 --> 00:00:27,693 Soy el camarero. 10 00:00:29,360 --> 00:00:31,660 ¿Tiene usted hambre o sed? 11 00:00:31,680 --> 00:00:33,940 Si, yo tengo hambre y sed. 12 00:00:37,080 --> 00:00:39,080 Aquí es el menu. 13 00:00:43,320 --> 00:00:47,400
...
etc.
Without the proper line breaks, the file is unreadable as a subtitle track by video players.
The SRT Formatter program takes the unformatted text in the "Motivation" section ... and transforms it into the following:
1
00:00:06,080 --> 00:00:06,780
¡Buenas tardes!
2
00:00:06,780 --> 00:00:07,560
Buenas tardes.
3
00:00:07,920 --> 00:00:10,480
Yo necesito una mesa y un menu.
4
00:00:10,900 --> 00:00:13,340
¡Si! ¿Usted tiene una reservación?
...
etc.
The SRT Formatter maintains proper character sets and supports multiple languages. For instance:
12
00:00:29,696 --> 00:00:30,797
火箭隊派對
13
00:00:30,797 --> 00:00:31,965
完美的執行。
14
00:00:31,965 --> 00:00:34,034
我覺得我的高中時代
15
00:00:34,034 --> 00:00:35,735
充滿了回憶，
...
etc.
