Closed Captions vs Subtitles: Key Differences Explained

‹ All articles

Understand the difference between closed captions (CC) and subtitles. Learn when to use each for clear, accessible video content.

Closed captions and subtitles are often used interchangeably, but they are not the same. Both appear as text on the screen, but they serve different purposes. Closed captions are meant to make things easier for viewers with disabilities by giving a full picture of the audio, including dialogue, speaker identification, and important sound cues. On the other hand, subtitles are meant to translate spoken dialogue for viewers who can hear the audio but don't understand the language. In simple terms, closed captions support accessibility, while subtitles support language comprehension.

To make good, inclusive video content, you need to understand the difference between these two. Choosing between captions and subtitles can affect how accessible your content is, how many people see it, and the overall user experience. Choosing the right format depends on what your audience needs and what you want to accomplish with your content. Read on for more details on the main differences so you can make the right choice and ensure your videos are both accessible and engaging.

What Are Closed Captions?

Definition of Closed Captions (CC)

Closed captions (CC) are on-screen texts that represent all audio in a video, not just spoken words. They include dialogues and important sound elements that help viewers understand the full context.

Captions are normally displayed at the bottom of the screen, depending on the platform or formatting. A key feature of closed captions is that viewers can turn them on or off. This distinguishes them from open captions, which are always visible.

What Closed Captions Include

Closed captions provide a complete and accurate representation of audio so viewers receive the same information as someone who can hear the video.

They may include descriptions of important sounds to help convey meaning and context.

They typically include:

• Spoken dialogue
• Background sounds such as [music playing] or [door slams]
• Speaker identification when it is not visually clear
• Tone or audio cues that add meaning

Captions are synchronized with the video for clarity and accessibility.

Who Uses Closed Captions

Closed captions are very important for accessibility, especially for individuals who are deaf or hard of hearing. They help viewers understand content without sound.

They are also often used for:

• Watching videos on mute
• Viewing content in noisy environments
• Improving focus and comprehension

Captions may be generated automatically, but human review is often needed for accuracy.

What Are Subtitles?

Definition of Subtitles

Subtitles are on-screen texts that show the spoken dialogue in a video. They are mainly used to help viewers understand what is being said, especially when the language in the video is different from their own.

Subtitles are often used for translation, including foreign language subtitles such as English or Spanish subtitles, allowing global audiences to access the same content.

What Subtitles Include

Subtitles primarily focus on the spoken dialogue in a video. They usually do not include sound effects, background noises, or detailed speaker descriptions.

Subtitles are typically limited to dialogue because they assume the viewer can hear the audio. This means they present the spoken content without additional audio context.

They typically include:

• Spoken dialogue
• Translated text when needed, such as English language subtitles

Who Uses Subtitles

Subtitles are commonly used by viewers who can hear the audio but do not comprehend the language.

They assume that the viewer can hear background sounds and tone, so they focus on supporting language comprehension.

They are often used by:

• International viewers watching content in another language
• Language learners who want to enhance their comprehension
• Viewers who prefer reading along while listening

Closed Captions vs Subtitles: Key Differences

Purpose and Audience

Closed captions and subtitles are created for different purposes, even though they may look similar on screen. Closed captions are designed for accessibility, helping viewers who are deaf or hard of hearing comprehend all audio elements in a video.

Subtitles are designed for viewers who can hear but do not comprehend the language. They are commonly used to translate dialogues and make content accessible to a global audience.

Content and Level of Detail

Closed captions provide a complete representation of the audio. They include more than just spoken words to provide a full audio context to the viewer.

They typically include:

• Dialogues
• Sound effects such as [music playing] or [door slams]
• Speaker identification when needed
• Tone or audio cues that add meaning

Subtitles, in contrast, include:

• Spoken dialogue (primarily)

They typically do not include sound effects or other audio details.

Language and Usage

Closed captions are usually written in the same language as the original audio. Their goal is to improve accessibility without changing the language.

Subtitles are often translated into different languages, but they can also be in the same language as the original audio. This enables the content to reach viewers from different regions and language backgrounds.

Audio Assumptions

Closed captions and subtitles are based on different assumptions about the viewer’s hearing ability.

• Closed captions assume the viewer cannot hear the audio, so they include all relevant sound information
• Subtitles assume the viewer can hear the audio but needs help understanding the language

This difference explains why captions are more detailed, while subtitles focus primarily on dialogue.

Types of Captions and Subtitles

Open Captions vs Closed Captions

Captions are delivered in two main formats: open and closed captions. Open captions are permanently displayed on the screen and are embedded into the video, also known as burned-in captions (burnt-in captions). This ensures viewers don't have to turn on captions, making the video available with open captions on all platforms. This type of caption ensures that all users can see it.

Closed captions, on the other hand, are optional, and viewers can turn them on or off. Most video players support them, allowing you to control how captions are used. Some platforms also support real-time captions for live content.

Subtitles for the Deaf and Hard of Hearing (SDH)

Subtitles for the Deaf and Hard of Hearing (SDH) combine elements of both captions and subtitles. When considering what the difference is between captions and subtitles, SDH includes both dialogue and non-speech elements.

Subtitles are usually limited only to show spoken dialogue, but SDH adds sound cues and tells you who is speaking. It might also work with audio description to make things more accessible.

SDH typically includes:

• Spoken dialogue
• Sound cues such as [music playing] or [laughter]
• Speaker identification when it is not visually clear

This format helps bridge the gap between captions and subtitles by supporting both accessibility and language understanding, making content more inclusive for a wider audience.

When to Use Subtitles and Closed Captions

When to Use Closed Captions

Closed captions should be used to make video content accessible without relying on audio. They are important for viewers who are deaf or hard of hearing, and standard captioning rules may require them.

They are made by a captioning process that includes transcription and timing. Some platforms automatically add captions, but you should check whether they are accurate.

When you should use closed captions:

• Accessibility or inclusivity is required or expected
• Your audience may watch videos without sound
• The content includes important audio elements

When to Use Subtitles

Subtitles are best used to help viewers understand dialogue in another language. They are commonly used for global audiences without changing the original audio.

Subtitles generally focus only on spoken words. They are often used for adding subtitles in different languages, such as English subtitles.

You should use subtitles when:

• You want to reach viewers who speak different languages
• You have to translate the dialogue into one or more languages
• You want to expand your content’s reach to global or regional audiences

In most cases, subtitles provide language support, while captions focus on accessibility.

Benefits of Using Subtitles and Captions

Accessibility and Inclusivity

Captions and subtitles make video content easier for more people to access. They help viewers who are deaf or hard of hearing understand what is happening in a video by providing clear text for spoken words and, in some cases, important sounds.

They also support a wider and more diverse audience. By adding captions or subtitles, you make your content more inclusive and easier for different groups of people to watch and understand.

Better Engagement and Viewing Experience

Captions and subtitles enhance the viewing experience for your audience. They make it easier to follow along, especially in situations when audio is not available or is hard to hear.

They are helpful when:

• Watching videos on mute, such as on social media
• Viewing content in noisy places
• Improving focus and understanding of spoken information

This can lead to better comprehension and help viewers remember key points.

SEO and Discoverability

Captions and subtitles can also help enhance your content’s visibility online. Since they provide text, search engines can read and index the information in your videos.

This can help:

• Improve search rankings
• Increase discoverability
• Make your content easier to find by a larger audience

Adding captions or subtitles is a simple way to improve both accessibility and online reach.
