Once you upload your videos into YouTube, the program will automatically create closed captions for you.
(If you don’t know how to upload videos into YouTube see my previous post http://edutips.commons.uaa.alaska.edu/uploading-to-youtube-and-embedding-videos-in-blackboard/)
Sign into YouTube and go to the creator studio. Once in there select the video you want to edit the closed captions.
Once opened, you’ll see the menu bar shown in the image below.
Select the CC button below your video to open up the Closed Captioning options. Once opened you’ll have to select a language in a dialog box select English. After you select English, you’ll see the English(automatic) button, click on that.
You’ll now be able to see all the Captions that are in the video and you’ll see and edit option which will prompt a popup that asks if you want to overwrite the existing subtitles, select overwrite. After that you’ll be able select through each caption in the correct time and edit them by simply clicking on the text box and typing in the correct wording. Once you have fixed the wording issues in the captioning simply hit the publish edits option and you will now have updated, correct Closed Captioning in your YouTube videos.
