Audio & Video Captioning

Most popular video streaming services provide automatic captioning of content.  However, the automatic captioning needs to be edited for accuracy.  Below, we detail how to edit the automatic captions generated by these services.

On the subsequent page, (3) locate the "Automatic" captions and select the "Duplicate and Edit" option on the right-side of the window.  If you do not see "Automatic" captions, and you recently uploaded your video, YouTube may have not generated them yet.  The time it takes YouTube to generate the automatic captions depends on the video's length and the complexity of the audio.  Check back again in an hour.
