If your video files don't have subtitle, you can look for correspondent subtitle file from internet or create a subtitle file by yourself.

Some player, like VLC, can load subtitle from independent subtitle file, while most popular video players, like Windows Media Player, QuickTime, iTunes, cannot.

If you want to show subtitle in these popular players, you'd better to add subtitle to the video file itself. If you want to play in mobile device, we suggest adding it as hard subtitle. Hard subtitle is one portion of the video image which means you cannot disable it, and all video players support it. On the contrary, soft subtitle is a stream in video files, you can show or hide it when play the video file. It needs more CPU power and is not supported by all players.

Introduction of One Common Subtitle File Format - SRT Format

SRT file is a simple text file, its content looks like this:

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

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


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 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.
