Why Add Closed Captions?

Reach a bigger audience

Research has shown that videos with captions get more online engagement and shares. And 85% of social media users watch videos without sound, so giving them a text version of your content is crucial!

Improve SEO and website traffic

Captioning your videos helps your content rank higher in search results by providing transcripts. It also increases audience retention and improves viewing time.

Better flexibility

We’re now watching videos everywhere, all the time. Audiences expect flexibility. Captions allow viewers to watch your video in environments where they can’t hear the action or they can’t play the audio out loud.

More inclusive content

Captions make your content accessible to people who are deaf or hard-of-hearing, and support those who have English as an additional language. They can also satisfy 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 the video.

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. They are also common on broadcast television and streaming media platforms such as Netflix.

Open Captions

Open captions have the same function as closed captions, but instead of being optional, they are ‘burned on’ to the video, so they are always visible to all viewers.

Open captions are used where videos are expected to be watched without sound, particularly on social media, where 85% of viewers have sound switched off. Open captions also suit situations in which you are showing a video to a large group and want to guarantee accessibility for everyone.

File Types & Formats

Ai-Media provides captions in any requested format such as SRT, STL, SCC, XML, SBV, DFXP, SMI, SAMI and WebVTT.

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

Live Captioning

Ai-Media also captions for live streaming content on multiple platforms. Find more information on our live captioning and live streaming pages.
