What Is an SRT File, & Why Is It So Important for Video?

Nowadays, 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.

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.

How to Create an SRT File

1. You can create an SRT file in any text editor, including Notepad, TextEdit, and Notepad++.
2. Open a text editor of your choice, and order each line of your subtitles, starting with 1.
3. Next, put the time the subtitle begins, then "-->", and the time it ends.
4. Format your timestamp like this -- "hours:minutes:seconds,milliseconds".
5. Below your start and end timestamp, put your first line of text.

Before we dive into how to edit an SRT file, let's take a look at an example of how one should be formatted:

If you notice your subtitles don't align with your audio, or you need to change the phrasing, it's easy enough to edit your SRT file. Consider using Subtitle Workshop, or another subtitle editor of your choice.

Alternatively, if you don't want to download an editor, you can open your SRT file in Notepad. You can change the time and phrases within the file, but don't change the punctuation. Then, click "File" → "Save as", and choose the SRT file extension.

How to Edit an SRT File

1. Download Subtitle Workshop.
2. Find "File" and then select "Load Subtitle" to insert your SRT file.
3. Click "Movie" and then "Open", and select the corresponding video file.
4. Next, select "Edit". You can choose from Timings, Texts, Subtitles, or Translations.
5. Adjust the time or the text on each line.
