What is an SRT file?

An SRT file is a subtitles file saved in the SubRip file format. It contains subtitle text and timing information. You can use SRT files to show subtitles in many different media players.

SRT files consist of subtitle text and timing information written like this:

1
00:00:03,400 → 00:00:06,177
In this lesson, we're going to
be talking about finance. And

2
00:00:06,177 → 00:00:10,009
one of the most important aspects
of finance is interest.

Media players load each segment of an SRT file in order, and they show each segment's text during the time period that text is associated with. SRT files' timecodes are written in the HH:MM:SS,MIL format. Thus, the first line of text shown above would appear on-screen at 3.004 seconds and disappear at 6.00177 seconds.

Display coordinates may appear after each segment's end timecode. If a segment contains no display coordinates, its text will appear in the bottom center of your display.

How can I validate that my SRT subtitles are formatted correctly?
