Enhance the Value of Your Videos

Use the power of captions to add value to your videos. Our captions allow you to reach a larger audience, improve the average watch time of your videos and make your content more accessible to people who are deaf or hard of hearing. Captions also enable indexing for SEO and better user engagement across online channels.

Adding captions to your video is essential to ensuring your message resonates online, maintains audience engagement, and allows for accessibility. Through captioning, we’ve helped deliver these benefits for Facebook, Amazon and the United Nations.

Why Add Captions?

Reach your whole audience

Because 85% of social media users watch videos without sound, it’s vital to communicate your message through text. Captions grab your viewers’ attention from the outset and hold it for longer.

Increase search indexing and traffic

Captions help videos rank higher in search results, increase audience website retention, boost engagement with content and improve overall user experience. These all improve your website’s SEO score.

Improved comprehension

Captions allow viewers to watch your video in environments where it is too noisy to hear the audio, or where it’s not appropriate to have the sound turned on. Captioning also reinforces your message.

Create more inclusive content

Captions make your content accessible to people who are deaf or hard of hearing, and assist people who have English as an additional language. They also allow you to stay compliant with accessibility regulations.

Captioning Options

Closed Captions

Closed captions appear as text overlaid onto your video and represent the speech, narration and sounds that occur throughout. Closed captions give viewers the option of switching the captions on and off. Most major video platforms support closed captions, including YouTube, Vimeo and Facebook. Closed captions are also common on broadcast television and streaming media platforms such as Netflix.

Open Captions

Open captions are only different to closed captions in that they are permanently embedded onto the video and are therefore always visible to every viewer. Open captions are used where videos are expected to be watched without sound, particularly social media content where 85% of viewers have the sound switched off. Open captions also suit situations when you are showing a video to a large crowd and want to guarantee accessibility for all.

File Types & Formats

We can provide captions in any requested caption format such as SRT, STL, SCC, XML, SBV, DFXP, SMI, SAMI and WebVTT.

We also support special requirements including colouring, positioning, and frame rates.
