Control who can see captions & transcript – CaptionHub

Normal Timbra projects are in public mode. This means the captions are accessible to all users who have the URL. This is intended for public video streams.

You can change the Visibility mode of the project under Advanced options. The options are Public (the default) and Private.

Private mode

In private mode the endpoints are locked down. Timbra exposes caption data only to users who are signed in to Timbra as a superuser, or as a producer on the project, and via the API.

You can use this feature to:

Evaluate CaptionHub privately (including downloading the output as VTT)

Build captions delivery with user authorisation using a proxy

Display in-room captions to attendees using the in-room display

Limitations in private mode

No support for the WebSocket API

No support for the in-room companion

No support for viewing the captions in a video via the HLS integration

Brightcove and Mux plugins can’t be used, but the Brightcove player can be configured to use captions using the Video.js plugin.

No support for the transcript widget
