Connect a player for live stream captions
Learn about adding captions to your live streams with CaptionHub
With CaptionHub Live you can seamlessly add captions to your live streams.
CaptionHub Live uses AI to transcribe, translate, and publish captions directly into video players, fully synchronised with stream audio.
Supporting 50+ source languages and simultaneous translation into 250 languages, it features termbases, custom dictionaries, formality settings, and full control over visibility.
CaptionHub Live uses the HLS output of a video stream. Using HLS’s built-in buffer, it produces captions just in time for the end user.
