How Do Subtitles Appear on Screens at In-person Events?

EventCAT provides four ways to deliver real-time subtitles to your audience.

1. Display the preview screen on a venue screen

2. View on personal devices via QR code

3. Share the subtitle page via URL link

4. Stream translated subtitles simultaneously using the Caption Overlay feature

All settings for each method can be easily configured on the EventCAT Controller page.
