What you need
- Voco Church plan (OBS integration included)
- OBS Studio (free — obsproject.com)
- A live Voco session
Setting up the OBS browser source
- 1Get your overlay URL from VocoIn the Voco dashboard, go to Integrations → OBS and copy the Browser Source URL for your desired output language.
- 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.
- 3Paste the URL and match the canvasPaste the Voco display URL. Set the browser viewport to match the region and resolution you designed for; 1920 × 1080 is common for a full-HD canvas, but it is not a universal lower-third size.
- 4Keep the live source connectedOBS documents that 'Shutdown source when not visible' unloads the page and that 'Refresh browser source when scene becomes active' reloads it. Leave both off initially so a hidden scene does not discard or repeatedly restart the live caption page.
- 5Position and style the overlayPlace the Browser Source above the camera or programme feed in the Sources list, then transform it into the safe lower-third region. OBS renders sources higher in the list above those beneath them.
- 6Test scene changes liveStart a Voco service, speak through the real pulpit microphone, switch through every scene used on Sunday, and confirm the captions stay connected and readable in both Preview and Program.
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.
Current OBS reference
OBS Browser Source is a built-in web renderer on Windows, macOS, and official Linux packages. Its URL, viewport, visibility, refresh, custom CSS, and page-permission controls are documented by OBS; use those current labels rather than copying settings from an old screenshot.
