What is closed captioning?

Closed captioning is the process of displaying a textual version of spoken content in video content, which typically runs along the bottom of the video screen. A central feature of closed captions in relation to other types of subtitles is that they can be turned on and off. It’s likely that you’ve encountered closed caption subtitles many times before, from streaming services to YouTube videos.

Closed captions were originally developed to aid those viewers who are deaf or hard of hearing. While traditional subtitles assume viewers can hear audio and simply present dialogue in a textual format, closed caption subtitles assume viewers cannot hear the audio. That’s why closed captions typically include relevant audio as well as dialogue, such as sound effects, laughter, or off-screen noises, like traffic in the distance or the noises of a bustling crowd.

Our Closed Captioning service

Using only expert, native subtitlers, our closed captioning service delivers high-quality closed caption subtitles for your project.

  • Firstly, you can tell us more about your project and your goals – whether that’s accessibility, optimising for SEO or reaching an international audience.
  • Then we will ask for your script, video or multimedia content.
  • Next, we will work with our professional subtitlers to create the captions, insert timecodes and sync the captions to the relevant audio. If you require multiple languages, we will draw on our network of native subtitlers across 220+ languages to complete the relevant closed caption translation.
  • Our captions will then go through our rigorous quality assurance process to check grammar, spelling, translation accuracy and synchronisation.
  • Finally, the finished project will be sent to you for your sign off.


Do you have an urgent deadline or a smaller budget than expected?

Which types of projects do we handle?

Our talented network of subtitlers can cover virtually every niche and sector. Our most popular project types for video closed captioning include:

  • TV, documentaries and films, including for streaming services
  • YouTube content
  • eLearning and training content
  • Marketing and advertising videos

Why invest in Closed Captioning for your content?

If you want to boost the accessibility of your content, enhance SEO and search engine rankings or expand the audience of your global ad campaigns, then closed captions are the perfect solution.

  • Expand your potential audience: Over 5% of the world's population – or 430 million people – experience hearing loss. Many more are hard of hearing or will go through age-related hearing loss at some point. This is a vast potential audience for your content, and it’s crucial that consider putting accessibility first by adding video closed captioning. It’s both a wise business move and an important ethical consideration.
  • Break down language barriers: 75% of the world’s population does not speak English at all, which could present a challenge to global communication for English-speaking companies. However, according to Ethnologue, did you know that almost half of the world’s population claims one of only 10 languages as their mother tongue? Our closed caption translation service could help you transcend language barriers to reach international audiences.
  • Drive traffic and sales with SEO: Search engines can ‘read’ closed caption subtitles. The search engine crawlers can index the text content, i.e. the subtitle file of your video content. This means video closed captioning can directly boost your Search Engine Optimisation efforts. In turn, higher rankings can help drive traffic and sales.
