Closed-captioning is available for any video that has been originally captioned by the service the video has been pulled from.
Enabling closed-captioning
When a user watches a video lesson which has closed-captioning, a “CC” button will appear. Click the button to enable/disable the subtitles.
Enabling subtitles in different languages
Some videos may be subtitled in different languages. To go through the options, click the “CC” button again.
No captions available
If the video doesn't have any available subtitles, the "CC" button won't appear at the bottom of the video.
Note: While some videos may contain subtitles on YouTube, many actually use a speech recognition technology to automatically generate subtitles. This feature is unavailable on Edpuzzle, as the automatically generated subtitles aren't always accurate.
