OBS sermon captions — how to add live translation to your church livestream

What you need

• Voco Church plan (OBS integration included)
• OBS Studio (free — obsproject.com)
• A live Voco session

Setting up the OBS browser source

1. 1Get your overlay URL from VocoIn the Voco dashboard, go to Integrations → OBS and copy the Browser Source URL for your desired output language.
2. 2Add a Browser Source in OBSIn OBS, click the '+' button under Sources and select 'Browser'. Name it (e.g. 'Voco Spanish captions') and click OK.
3. 3Paste the URL and set dimensionsPaste your Voco overlay URL. Set the width to 1920 and height to 200 (for a standard lower-third bar). Tick 'Shut down source when not visible' to save resources.
4. 4Position and style the overlayDrag the browser source to the bottom of your scene. The Voco overlay has a transparent background, so it layers over your video feed cleanly.
5. 5Test liveStart a Voco session and speak a test sentence. Captions should appear in the OBS preview within ~500ms.

Using captions for in-room screens vs livestream

You can use two separate OBS scenes or outputs: one with captions for your in-room projector feed, one without for social media livestreaming (where the broader audience may not need translation). Alternatively, run one output with captions for all viewers — many churches find international livestream viewers appreciate translated captions.
