What is an .srt file?

 
 

INTRODUCTION

Subtitles are becoming increasingly common, particularly as businesses expand their marketing efforts and aim to reach a broader, global market. Additionally, subtitles are often necessary to ensure your video and audio files are as inclusive as possible.

Fortunately, there's an easy solution to adding subtitles to video - an SRT file.

To ensure your videos are inclusive and easily digestible for any audience, it's critical you include an option to watch with subtitles. Here, we'll explain what an SRT file is, and how to create and edit one for your marketing videos moving forward.


SO WHAT IS AN .SRT FILE?

An SRT file (otherwise known as a SubRip Subtitle file) is a plain-text file that contains critical information regarding subtitles, including the start and end timecodes of your text to ensure your subtitles match your audio, and the sequential number of subtitles.

It's important to note, an SRT file is just a text file you would use alongside video or audio -- it does not also include the video or audio you're subtitling.

SRT files can be created from scratch or downloaded and edited. Before we get into the basics of editing SRT files, let's take a look at what an SRT file looks like and how it's formatted.

 
 
 
 

SRT FILE EXAMPLE

Generally, Wordpad or Notepad (or TextEdit on MacOS) are the easiest programs to open SRT files with because you can view them in plain text.

In order for an SRT file to work in conjunction with the video or audio file it's paired with, it must follow a specific format consisting of: 

  1. The line number

  2. The time range where the line should appear in the video

  3. The text that should appear on the line

The timestamp is formatted like so with the milliseconds rounded to three decimal points: 

Hours:Minutes:Seconds,Milliseconds

The timeframe is formatted like so with an arrow denoting range:

[First Timestamp] --> [Second Timestamp]

The arrow must consist of two hyphens and a right-pointing angle bracket (also known as the greater-than sign or carrot).


If you're creating one from scratch, feel free to copy and paste this sample SRT formatting:


Example SRT Formatting

1
00:00:00,000 --> 00:00:00,000

<b>Insert your first line of text here, and don't forget to change the timestamps.<b>

2
00:00:00,000 --> 00:00:00,000

<b>Insert your second line of text here, and don't forget to change the timestamps.<b>
