SproutVideo offers the ability to display subtitles along with videos. We currently support subtitles using the WebVTT standard. We do not currently support the entire standard. If you have any questions about our implementation or what do do and do not support, please contact our support team.
Go to the video for which you'd like to add subtitles, then expand the "Additional Video Settings" section, and click on the "Manage Subtitles" button:
Click the "Add New Subtitle Track" button:
Select the language for the subtitle track, paste the WebVTT formatted subtitle contents into the box provided, and click the 'Add Subtitle Track' button:
Your video will now display the subtitle button in the video player and viewers will be able to select the subtitle track when watching the video.
We chose the WebVTT standard because it is starting to become widely adopted by all of the major web browsers for HTML5 subtitle and captioning support and provides a simple, extensible, and human-readable format on which to build timed text tracks. The WebVTT format is very simple. A WebVTT file must start with the header "WEBVTT". After that it is followed by one or more "cues". At it's simplest, a cue consists of a "timing" and "cue text". Here is an example:
WEBVTT 00:00:01.000 --> 00:00:10.000 This is the first line of text, displaying from 1-10 seconds 00:00:15.000 --> 00:00:20.000 And the second line of text, appearing from 15-20 seconds

Subtitles are supported on all devices when using the Adobe Flash video player. The HTML5 player supports subtitles in the following environments:
