Video Captioning in a Nutshell

Video captioning is the process of adding text to a video or audio file in order to provide additional information such as dialogue, sound effects, and music. Captions are typically embedded directly into the video file, allowing them to be displayed alongside the visuals. When it comes to a large company that needs to provide many captions or one that wants to use such technology, using closed captioning service providers can be a great option.

Benefits of Video Captioning

Video captioning can be beneficial for viewers, creators and even marketers. For viewers, captioning provides a more accessible way to understand video and audio content. For example, it can be used to help those with hearing impairments or limited English proficiency. Captioning also makes videos easier to follow for viewers who are in noisy environments or have difficulty understanding the speaker’s accent.

For creators, captioning can be used to increase the reach of their videos. Adding captions allows more people to view and understand the video, leading to higher engagement rates and increased visibility.

For Marketers, video captioning can be used to increase search engine visibility and optimize videos for SEO. Adding captions allows search engines to index video content, improving the chances of it appearing in relevant searches.

Moreover, captions can also be used to add context and additional information that may not have been able to be communicated via audio or visuals. This is especially true if you are using voice-over talent. While this can add to the cost of the project, the cost of voice over is usually reasonable and within budget for most marketing departments.

Different Types of Video Captioning

The most common type of video captioning is closed captioning, which provides subtitles for spoken dialogue and descriptive text for other audio elements. Closed captioning is usually embedded directly into the video file, allowing it to be displayed alongside the visuals.

Open captioning is also available, which displays captions permanently on the video rather than being embedded in the file. This type of captioning is useful if you want to reach viewers who have difficulty understanding the dialogue or audio elements.

Another type of video captioning is voiceover captioning, which combines the benefits of both closed and open captioning. This type of captioning requires a professional voice actor to provide both descriptive text and spoken lines synched with the visuals.

Implementing Video Captioning Effectively

Now that you understand the different types of captioning available, it’s time to learn how to implement them effectively. The first step is to create a transcript of your video, which will be used as the basis for the captions. Once you have a transcript, you can use software such as YouTube or Apple Final Cut Pro X to create and edit the captions.

It’s also important to make sure your captions are accurate and up-to-date, as this will ensure viewers have a better experience when watching the video. You should also consider adding extra features such as positioning options and custom fonts to make the captions more engaging.

Finally, it’s important to test your captions to make sure they are working properly and can be viewed easily on all devices. This is important for ensuring a positive user experience and meeting accessibility requirements.

Are They Legally Required?

In some jurisdictions, captioning is legally required for certain types of video content. For example, the UK’s Equality Act 2010 requires that all business videos and audio-visual materials are accessible to everyone. In the US, the Americans with Disabilities Act (ADA) has similar requirements. When it comes to films and television shows, the Federal Communications Commission (FCC) requires that all programs broadcast on US television be captioned for viewers with hearing impairments.

Regardless of legal requirements, it’s always a good idea to use video captioning to make your content more accessible and engaging for everyone.


Overall, video captioning can be a great way to increase visibility, engagement rates, and accessibility for your videos. It’s important to understand the different types of captioning available, as well as how to implement them effectively. Finally, it’s important to be aware of any legal requirements around video captioning in your jurisdiction. With the right approach and tools, you can ensure that all of your viewers have an enjoyable experience when watching your content.
