It's the format of the srt file. ```text 1 00:00:00,000 --> 00:00:07,560 これは字幕ファイルから読み取った字幕です。 2 00:00:10,230 --> 00:00:14,700 This is a test video ``` 1. Write timestamp for start time and end time of the text to be displayed 2. Write the text one line below the timestamp Timestamp is written like `hh:mm:ss,sss --> hh:mm:ss,sss`. `hh` is the hour, `mm` is the minute, `ss` is second, and `sss` is millisecond. `:` is a delimiter for `hh`, `mm` and `ss`, and `,` is a delimiter for `hh:mm:ss` and `sss`. Start time, ` --> `, and end time, in that order. Actually, if it's written in this format, you don't have to worry about the file extension.
