Subtitles and closed captions in Gradual

Auto-Generated or Human Generated Captions in Gradual virtual events

Updated over a week ago

Offer auto-generated captioning for all your virtual events in Gradual! This is available in livestream events, webinars, and meeting rooms, and to all customers.

Auto-generated captions only support English at this time, but will attempt to translate non-English spoken audio to English.

There are two modes for captions in livestream stages: automatically generated captions and human-generated captions. Automatically generated captions are available to enable in the dashboard for all events.

Captions in Livestream Events

Gradual livestream events support displaying auto-generated captions on each stage within your livestream event.

Enabling captions in livestream events

You can opt to enable captions by default for all livestream events, or on a per-event, per-stage basis.

Enable captions by default for all livestream events created

If you'd like all livestream events to automatically enable captions by default, the dashboard admins can make that setting change in the main dashboard.

  1. Navigate to the main dashboard and to the Events tab

  2. Select the Settings button in the upper right

  3. Toggle on 'Live captions for livestream events'

  4. Once this is enabled, captions are turned ON for all newly created livestream stages moving forward

Enable or disable captions per-event or per-stage

To enable or disable captions in the event, for a stage, you can do so via the dashboard.

  1. Navigate to the dashboard and to the event dashboard

  2. From the Event SetUp tab, navigate to the Stage Settings

  3. Select the stage where you'd like to enable and offer captions

  4. Select the Edit text in line with that stage, to open the Edit Stage pop up

  5. Toggle on 'Live Captions'

  6. This will offer captions on that stage only - if you'd like it to be available on all stages, you will follow steps 3-5 for each stage

To enable or disable captions for a stage, you can do so via the dashboard from within your event under Event Setup --> Stage Settings --> Edit

Captions can be enabled or disabled per stage. This means you can have stages within the same event with or without captions or different caption modes.

Human-Generated Captions

If you do not wish to use auto-generated captions within Gradual, you may use other commercially available tools (e.g. AI-Media, EEG Falcon, 3Play, Verbit, Webcaptioner) to embed your captions into your H.264 RTMP stream and displayed in Gradual.

Gradual supports receiving closed captions embedded in the H.264 video stream using the CEA-608 standard for a single language. Captions are by default configured to be US English (en-US) and should be transmitted on caption channel 1 (cc1). These are the default configurations for most caption providers.

If you want to use this method of captions, please reach out to Gradual Support at [email protected] well in advance of your event so the proper settings can be adjusted.

User experience - Live in the event

Captions will not automatically appear for users, but attendees can opt to generate the captions from the CC button in the settings bar at the base of their video feed. This is available for users on a computer browser or a mobile device.

The CC button will appear once the host has started streaming, and there is spoken word.

Auto-generated captions only support English at this time, but will attempt to translate non-English spoken audio to English.

Gradual meeting and webinar events support displaying Closed Captions in the main room and in all breakout rooms.
