About

In Kaltura’s Video Portal, you can upload extended audio description (EAD) files for media you own or have editing privileges for.

Extended audio description files are time-coded text files that the Kaltura player converts into spoken narration using browser speech synthesis. They make visual content in videos accessible for people with visual impairments.

EAD files are uploaded in VTT format and managed from the Captions tab, alongside caption files, using a dedicated upload option.

Access the extended audio description settings

1. Go to your My Media page.
2. Locate the video you want to add extended audio description to and click the pencil icon to the right of it.



The edit page opens with the Details tab selected by default.



3. Click the Captions tab to open the settings.

4. Type in a label (it's advisable to add an “EAD” suffix to clearly identify the file as extended audio description).
5. Click Save to upload the file.
