Forcing Closed Captioning On for YouTube Videos
Apr 15, 2017
If you are a YouTube publisher and added closed captions (CC) to your video, you will find that YouTube does not show these closed captions by default. The viewer usually controls the CC settings when watching the video and by default, YouTube sets it to off.
As a publisher, you sometimes feel the need to force closed captions on. For example, For example, I soccasionally forget to mention a few things when recording training videos. It does not make sense for me to spend time re-recording the entire session. So I just add closed captions at appropriate points and force the functionality on. My added tips show up where I inserted them as closed captions irrespective of viewer's YouTube settings. Obviously the viewer can switch this off while watching the video and it is their choice.
To force closed caption on go to Video Manager and edit your video. In the tags field, add a tag
yt:cc=on. You are done.
