Why add captions, you ask? Adding captions and subtitles makes your videos more accessible to people who can't follow along with the audio -- either because they speak a different language, or because they are deaf or hard of hearing. To get started, simply:
- Open one of your videos in the lightbox view (from the Videos tab on your profile, for instance)
- Click 'Options' at the bottom-left of your screen, then choose 'Closed captions'
- Click 'Add new captions or transcript' in the video details pane, then upload your file
If a video on Google+ has captions available, just click the 'CC' button to turn them on. If you'd like more details on creating and uploading captions, feel free to check out the Google+ Help Center (http://goo.gl/YCpQk).
Let us know what you think in the comments, and happy captioning!
