Facebook allows you to add captions to uploaded videos. To take advantage of this feature, you'll first need to make a subtitle file. InqScribe is here to help.
The following process entails creating your transcript, exporting it to the Facebook-compatible SubRip .srt format, and finally uploading your video along with the .srt file to Facebook. Note that, at this time of writing (February 2017), adding captions is only available in the US for the English language, and it won't work on mobile or tablet. This is subject to change as Facebook continues to develop their video features. In the likely even that Facebook alters their subtitling process, we'll try to keep these instructions updated.
Facebook is a little picky when it comes to the format of the SubRip .srt captions, so pay special attention your filename and line endings (see steps 3 and 4). With that in mind, here's how to add in your captions:
If you didn't name the .srt file correctly, you'll see the message "You uploaded a .SRT file with an incorrect filename. Please use this format: filename.en_US.srt"
If you don't see any subtitles after uploading your .srt file and clicking the "CC" button on the video player, then you might not have selected the correct line endings in step 4.
You can also add subtitles to a video you've already uploaded. To do so, select the video and expand it. Click "Options > Edit This Video" at the bottom of the video player and refer to steps 7-9.
