Importance of Punctuation in Closed Captions

When creating videos, Closed Captions are an essential component of making your content more accessible. Not only are they important for viewers who are hard of hearing, but they can also lead to a better overall user experience on your platform. However, there is often confusion around whether or not closed captions should include punctuation. In this blog post, we will explore the importance of punctuation in closed captions.

What Are Closed Captions?

Closed Captions are a text version of the audio in a video. They are not shown by default and viewers typically have to turn them on manually. Closed captions help to make videos more accessible to a wider audience including viewers who are deaf or hard of hearing, non-native speakers, and those in environments where they cannot listen to audio. Closed Captions contain all of the dialogue, sound effects, and other audio elements that are present in the video.

Why is Punctuation Important in Closed Captions?

Punctuation is crucial in written English and Closed Captions are no exception. Punctuation helps to convey meaning and ensure that the text is readable and understandable for the viewer. In Closed Captions, punctuation can be especially important, as the audience relies solely on the written text to understand what is being said. Improper punctuation can lead to confusion and misinterpretation of the message.

For example, consider the following sentences:

– “Let’s eat Grandma.”
– “Let’s eat, Grandma.”

The placement of the comma in the second sentence completely changes the meaning of the sentence. Without the comma, the sentence suggests that someone wants to consume their grandmother. With the comma, the sentence suggests that someone is inviting their grandmother to eat with them.

This is just one example of how punctuation can be crucial in conveying meaning. When it comes to Closed Captions, proper punctuation ensures that the text accurately reflects the audio in the video and conveys the intended message to the viewer.

When Should Punctuation be Used in Closed Captions?

As a general rule, Closed Captions should follow standard punctuation guidelines. This means that periods, commas, question marks and exclamation points should be used where appropriate. Other punctuation marks, such as colons or semicolons, may also be used but should be used sparingly.

Punctuation should be used to indicate where one sentence begins and ends, to distinguish between different speakers, to indicate emphasis, and to indicate non-speech sounds such as music or sound effects.

However, it’s important to note that Closed Captions are not a direct transcription of the spoken word. They need to be edited for clarity and readability. This means that you may need to remove unnecessary words or punctuate differently than in the spoken audio to ensure that the message is conveyed accurately.

Best Practices for Closed Captioning

In addition to using proper punctuation, there are other best practices to keep in mind when Closed Captioning your content. These include:

– Accuracy: Closed Captions should accurately reflect the spoken audio.
– Consistency: Use consistent placement of text and font size throughout the video.
– Clarity: Closed Captions should be clear and easy to read.
– Timeliness: Closed Captions should appear on the screen in sync with the spoken audio.
– Captions for Non-Speech Audio: Include Closed Captions to indicate any non-speech audio such as music or sound effects.


Closed Captions are an essential part of making your video content accessible to a wider audience. While some may question the importance of punctuation in Closed Captions, it’s clear that proper punctuation is crucial to accurately convey the intended message to viewers. By following best practices for Closed Captioning, you can ensure that your content is accessible, clear, and easy to understand for all viewers.
