Kaltura video owners or co-editors can upload captions files which were created outside of Kaltura (manually created or created by a 3rd party vendor such as 3Play, for example).
A video owner or co-editor can upload externally-created captions files by following these steps:
Go to Kaltura's "My Media"
1a) In Canvas, go to Canvas > Account > My Media.
1b) In Mediaspace, go to Guest > Login, then [Your Name] > My Media.
2. In My Media, select a video from your list of videos.
3. In the drop-down menu below the preview of the video, click Actions > Edit.
4. On the Edit screen, click the Captions tab, then Upload Captions File.
5. Select a captions file from your computer. Common file formats include ".srt" and ".dxfp," and ".vtt."
6. Enter the label text which will appear on the Captions menu in the video player: "English" or "Spanish," for example.
7. Click Save.
