Making audio and video content more accessible can be done via closed captions. Captions are a text version of the dialogue and sounds in a video and are displayed on screen in time with the soundtrack. Something as simple as text at the bottom of the screen can make a whole world of difference for many people, and make the content available to all.

Once you’ve written your captions and made sure they have perfect timing and impeccable grammar, the last step is to add them to your video. But how do you upload the captions to your video?

Check out this quick guide to uploading caption files to the three biggest video platforms – YouTube, Facebook and Vimeo – so you can make your videos accessible to everyone.
