Closed Captions and Subtitles: Boost Video Accessibility and Engagement

Posted: | Last updated:

Did you know 5% of the world's people have trouble hearing? This highlights a big reason to use closed captions in videos. Without these, a lot of people might miss out on your content. In today's world, being online is key for any business. And video is a great way to connect with customers. With more people choosing to watch videos online over TV, it's vital to make sure your content is accessible. So, include closed captions or CC to broaden your reach. For years, closed captions have helped those with hearing impairments to enjoy videos. They make media more accessible for over 5% of the global population who face this challenge. By adding captions that are clear, easy to read, and well-timed, you can make sure everyone enjoys your videos. It's an investment that pays off in better engagement with all viewers.  

Key Takeaways

  • Closed captions are essential for ensuring content is accessible to viewers who are deaf or hard of hearing.
  • Around 5% of the global population has some level of hearing loss, and not having closed captions can exclude them from your video content.
  • Closed captions can enhance the viewing experience and help businesses reach a wider audience.
  • Investing in accurate and well-synchronized closed captions can be achieved through professional transcription services.
  • Closed captions and subtitles can significantly improve the accessibility and engagement of your video content.

What are Closed Captions?

Closed captions show text of what's being said in a video. They help people who can't hear clearly, or not at all, to know what the video's about. This text even includes who's speaking and sounds that are key to the story.

Definition of Closed Captions

Closed captions turn video sound into words on the screen. This way, anyone can understand the video's sounds and dialogues. It's especially helpful for those who are deaf or have trouble hearing.

Types of Captions

There are two types of captions: closed and open. Closed captions can be hidden by the user, while open captions are always shown because they are part of the video.

Closed Captions vs. Open Captions

CC can be turned on or off based on the viewer's choice. Open captions, on the other hand, are always there, making it impossible to hide them. This feature lets viewers decide if they want to read the captions or not.

The Importance of Closed Caption Quality

High-quality CC are vital for engaging and accessible video content. They should aim for a 99% accuracy rate, focusing on punctuation, spelling, and grammar. This high level of accuracy is crucial because a 1% error rate might lead to misinterpreting complex content.

Accuracy Standards for Closed Captions

It's crucial that a video's closed captions are right and not wrong.
For sentences about 8 words long, a 95% word accuracy means there's an error roughly every 2.5 sentences. This frequent error rate can significantly hinder a viewer's understanding. Since most automatic tools only hit an 80% accuracy, they fall short of producing top-notch captions.

The Cost of Inaccurate Captions

Flaws in CC can lead to several issues. They force creators to spend more time fixing mistakes and may cause viewers to miscomprehend the video's message. This, in turn, can hurt the brand's trust and the overall viewing experience.

Closed Captioning Standards and Guidelines

The FCC, DCMP, and WCAG have set standards for quality closed captioning. By following these best practices, content creators ensure their video content is both accessible and engaging. This approach helps in maximizing the effect of the videos they make.

The Benefits of Closed Captioning

CCs aren't just for people with hearing issues. They also help businesses and reach more viewers. Around 5% of the world's population deals with hearing loss. If your media lacks captions, you might miss connecting with those people.

Improved Accessibility for Deaf and Hard of Hearing Viewers

For the deaf and hard of hearing, captions are a lifeline. They translate all audio, even the sounds that aren't speech. This makes video content fully understandable for them.

Better Comprehension for Non-Native Speakers

Non-native speakers can also benefit greatly from captions. Captions turn speech into text, aiding global audiences in understanding the content. Thus, captions improve reach and accessibility for businesses.

Enhanced User Engagement and Watch Time

Captions boost how long people watch videos and how involved they are. They let viewers understand videos without sound, which is handy in noisy or quiet environments. This benefit is big for those watching in public or at work.

Search Engine Optimization Advantages

SEO-wise, captions are a goldmine. They provide search engines with more text to identify your content. This can increase your video's visibility, drawing in more viewers and engagement for your business.

Understanding Subtitles

Subtitles show the text version of audible content. They translate speech into another language. Subtitles are used when the listener can hear the talks but doesn't understand them. Also, subtitles don't cover extra audio details or who's talking. They focus only on the words spoken.

What are Subtitles?

Subtitles help videos reach people worldwide. They translate the talk for viewers in different parts of the world. This makes them a key part of films and shows, making them accessible to many. They are useful for those who watch videos silently, like on their phone.

Creating and Implementing Subtitles

To make subtitles, the spoken words are written down. Then, these words show up on the screen when the character speaks. This makes sure the subs match the video perfectly. The subs can be shared with the video directly or as a separate file. Viewers can then choose to turn them on or off.

Subtitles for Global Reach

Subtitles bring videos to more people by offering translations. They let those who don't speak the video's language understand what's happening. This is vital for businesses and creators who want to reach a worldwide audience. Adding subtitles can boost how many people watch and engage with your videos.

Closed Captions vs. Subtitles

Are closed captions and subtitles the same? While closed captions and subtitles might look alike, they have different jobs. CC help improve search results and make videos easier to follow for the deaf or hard of hearing. Subtitles, though, are key for reaching more people worldwide, especially for viewers who speak a different language. The big difference between closed captions and subtitles is what they aim to do. Subtitles make content more accessible to diverse viewers, while closed captions focus on helping those with hearing or accessibility challenges.

Though they look similar, closed captions and subtitles do not work the same. Closed captions boost accessibility and improve search engine results, while subtitles are how you connect with viewers around the globe and those speaking other languages. Knowing how they differ is vital for creators to reach the broadest audience and provide a seamless viewing experience. Closed captions and subtitles look similar, but they serve different purposes. I will show you why content creators need to know the differences. I'll talk about how they affect accuracy, the fullness of content, language uses, how everyone can access them, and who the target audience is.

Accuracy and Comprehensiveness

Closed captions are detailed and include everything spoken and non-spoken. This includes sound effects and identifying who is speaking. This extra information helps people who are deaf or hard of hearing understand the video better. On the flip side, subtitles just translate what's spoken into a different language, lacking these detailed features.

Language Compatibility

Subtitles are more versatile when it comes to languages. They can be in many languages, opening up content to a wider audience. Meanwhile, closed captions usually only come in the video's original language. This means they might leave some people out.

Accessibility Considerations

In terms of accessibility, closed captions win. They work with screen readers and other support tools for those with disabilities. Subtitles are useful for language translation but lack these key accessibility features.

Target Audience

Subtitles are great for making content worldwide and helping people learn new languages. Check out this Hootsuite review and see if you can use the tool for subtitling or closed captioning.

Best Practices for Closed Captioning and Subtitling

Exploring closed captioning and subtitling showed me how important following best practices is. It's key for making these tools accessible and effective. No matter if you're adding captions or subtitles to your videos, remember these tips.

Timing and Readability

Proper timing and being easy to read are critical for closed captions. They should match the audio and be clear. This allows everyone to easily understand what's being said. Captions should show only a bit of text at a time. For example, each caption should have 30 or fewer characters and span no more than two lines. This helps keep things tidy on-screen.

Speaker Identification and Sound Effects

Closed captions need to show who's talking and any important sounds. This adds more context, especially for those who can't hear well. It makes the content richer and more engaging for all viewers. Look into this DaVinci Resolve 14 review to see how this editing tool can help you with sound effects and captions.

Translation and Localization

Translation is important because you have different viewers.
Subtitles must accurately translate and localize dialogues. They should flow naturally with what's being said. But it's not just about direct translation. Subtitles need to capture the culture and idioms of the audience they're meant for. This makes the video more relatable to viewers from different places. Putting in this extra work improves the viewing experience a lot. Following these practices helps creators get the most out of their videos. It lets them reach a broader audience and makes their work more accessible. It's a smart step that boosts the video's impact and appeal.


Both closed captions and subtitles are great for helping everyone enjoy videos more. Closed captions are a must for those who are deaf or hard of hearing. They show everything being said, even the sounds. Subtitles, on the other hand, change the words into another language. This helps videos be understood by more people all over the world. Choosing between closed captions and subtitles depends on your video's message. But having high-quality ones can make your video better for everyone. It makes it easier for more people to watch and enjoy what you've made.
