As with many aspects of digital accessibility (a11y), when it comes to how you should caption your video content, it depends!
What are captions?
In short, captions are words!
Captions generally appear at the bottom of your video content, and there are different types of captions that a content creator can use. The types of captions are defined by how they are accessed, how they appear, and the kind of information they provide.
While we will focus on closed captioning (CC) today, this article from the Described and Captioned Media Program explains more about the different types, methods, and styles of captions. Closed captions are words that are added to a video so people know what’s being said when using audio isn’t the best option for them.
Adding captions to your video content is an example of inclusive design. Inclusive design is a fancy way of saying, “making your content usable by as many people, in as many situations, as possible.”
Benefits of captions
In general, adding captions to your videos can help:
- Accessibility: Captions make videos accessible to people with hearing impairments, so they can understand the content and not miss valuable information. Hearing impairments might include:
- Permanent disabilities such as profound deafness.
- Temporary disabilities such as impacted earwax.
- Situational disabilities such as being in a loud room or while using public transportation.
- Enhanced learning: Captions aid in educational settings by reinforcing key points and helping learners understand the material better.
- Social media engagement: Social media platforms often auto-play videos without sound, making captions important for engaging viewers.
- Meta reports that video content with closed captioning has a 12% increase in viewership over video content that does not contain closed captions.
- In another study from Meta, it is reported up to 85% of videos viewed are viewed without sound. If you want to get your message to your audience, your message should be understandable without sound!
- Legal requirements: Some regions or organizations have legal requirements or accessibility standards that mandate using captions for certain types of content.
If you are interested in diving deeper into the ways that closed captioning can boost engagement, this Teaching Brief from The Journal of Public Relations Education (PDF) goes into much more detail about the “why” behind using CC (and teaching it to others!).
Getting started with Closed Captioning
Different media platforms will have various levels of access and control for you to add captioning. In this post, we will focus on video content hosted on YouTube.
The basic process for adding Closed Captions to your YouTube video content is the following:
- Upload your content to your YouTube channel.
- Ensure the settings create automatic closed captioning.
- Wait for YouTube to process your video and the automatic closed captioning.
- Edit the automated closed captioning.
- Automatic closed captioning is not very good at accuracy or timing – if you can, you should always edit the closed captions manually.
- Be sure to add the names of speakers, especially if they are speaking off-camera. Something like, “[Brent] Oh, look at these great captions.” would be perfect!
This tutorial from YouTube Creators will walk you through several ways to add custom closed captioning to your YouTube video.
And that's it!
Getting started with adding closed captions to your video content is a big step in the right direction for making your content more accessible. Because different media hosting platforms (Vimeo, X (formerly Twitter), TikTok, etc.) have different levels of control and access to captioning tools, you may need to approach each platform differently.
Remember, it depends!
