Now you can make sure that your live broadcasts are as accessible as possible to all your viewers by adding captions to your live videos. Displaying subtitles and text tracks on your live video lets you control the accuracy of your messaging, and allows you to reach a wider audience, including those who rely on text to watch videos. This improves accessibility and comprehension for the entirety of your audience. In addition, subtitles empower your viewers to digest the message in whichever way is best for them, be it audio, text, or a combination.
Captions in the live video will be saved in the archived version of the video, should you choose to keep the archive, so that your viewers can return and watch key moments with captioning.
In order to add captions to your live video, you will need an encoder that supports 608 captions. If an encoder can stream via RTMP and transmit CEA-608 closed captions either via SDI or a cloud service, those captions will be available in the Vimeo live player as well as in the stream’s archive.
We encourage you to test out your workflow prior to your event; you can do this with an unpublished (draft) event or create a hidden event and go live prior to embedding it to your website.
