Captions and Subtitles with Facebook Video
Facebook values videos like never before.
Compared to posting YouTube videos on Facebook, videos uploaded natively to Facebook get more impressions on the newsfeed. They also auto-play on mobile and desktop, albeit without audio at first. Facebook even introduced a beta ad revenue sharing feature for high-volume Facebook video publishers.
If you want to optimize your Facebook videos for the best user experience, make sure to add closed captions. To reach a multilingual audience, add subtitles in other languages.

Facebook launched the ability to add closed captions to your videos, which solves the problem of auto-playing a silent video. How many times have you started watching a video on Facebook in a location where you can’t play the sound (office, subway, library) and wished that you could understand what was going on?
Well, now you can!
Of course, closed captions will also make your videos accessible to people who are deaf or hard-of-hearing, and to people who know English as a second language.
How Facebook Video Captions Work on Mobile
Closed captioning functionality on mobile phones varies by device.
For iOS devices, closed captions will display when the Facebook video autoplays on mute. But when you tap the video, the closed captions turn off and audio turns on. There is no way to turn CCs back on from the full-screen view.
If your iPhone accessibility settings are set to ‘Captions On,’ then it will play audio and display captions on Facebook videos, but there’s no option to then turn CCs off.
Closed captions will autoplay on Facebook videos in your mobile newsfeed. Closed captions can be toggled on or off regardless of your phone’s accessibility settings.
How to Add Closed Captions to Facebook Videos
It’s really easy to add closed captions to your videos on Facebook! You can do it all from your 3Play Media account. Just upload your video and submit it for captioning, and you’ll get an email when it’s finished processing. Select your file and select Download, then choose the Facebook SRT Web caption file format.
The Facebook SRT file format looks like this for American English content: yourfilename.en_US.srt.
The name of your finished file will have a slightly different ending if the content is in a different language or dialect.
Next, upload your video to Facebook. When the video is done processing, click the Edit Video prompt to add captions. In the caption field, click Upload SRT File and select your Facebook SRT file.
Remember to save your changes, and view your Facebook video with captions!
