If you’ve enabled auto-captioning in your Zoom meeting settings, a captions file is available for your video in Kaltura. It will be in the format .VTT. Another method of generating a captions file is available directly in Kaltura.
Enabling machine captioning is the first step in providing an accessible video. Although machine-generated captions are more accurate than they once were, to ensure the accessibility of your video it’s necessary to edit the captions and correct any errors.
