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.

How to Edit Zoom Automatic Captions

Captions are automatically added to Zoom videos when they are saved in the cloud.  These captions can then be edited online in the UNT Zoom web portal

If you have saved your Zoom meeting recording locally to your own computer, rather than in the cloud, please refer to the Sharing a local recording Zoom Help Center page.

To start, log into the UNT Zoom web portall.  Select (1) "Recordings" in the left-side navigation bar, and then (2) select the title of the video for which you wish to correct the captions from the list in the central pane of the web portal.

Within the subsequent page, the captions should appear along the right side.  If there are no captions, and this is a recently recorded Zoom meeting, then Zoom may not have finished generating them.  Check back again in an hour.  Scroll through the captions on the right side.  When you find a caption in need of editing, hover your mouse cursor over it and an edit icon in the shape of a pencil in a box will appear.  Select (4) the icon, to edit the caption text.
