Vito supports attaching WebVTT (or VTT) files to pre-recorded videos. This is a specific format of text file with timestamps that video players can use to display an overlay of captions and/or subtitles for the audio track of your video. These can be toggled on or off by the participant, using the media player controls.
Currently, you need to head to your hub’s Backstage area to add VTT captions to videos.
Next, click on the Content menu item and select Videos from the dropdown. You’ll see the media library and be able to select the relevant video.
From there, click the blue button to add captions or subtitles, enter the language and label (these should match) and upload your VTT file. It will be attached to the video right away. You may need to republish the video in the hub for the captions icon to appear.
