Adding Closed Captions to Your YouTube Video

Video files uploaded to YouTube are automatically closed captioned. The closed captions appear after a delay (perhaps tens of minutes depending on the length of the video and the demands on YouTubes services). 

To edit the closed captions created by YouTube:

1. Log on to studio.youtube.com with the account used to upload the video (see figure 1).
