Putting BabelCast captions into OBS and ProPresenter
BabelCast captions live in the browser, so they drop into almost any production tool that can show a web page. If you run OBS or ProPresenter, you can have translated captions on the big screen in a couple of minutes using the session's display view.
Adding captions in OBS
Copy your meeting's display link from its page in the portal (or open the display view and copy the URL from the address bar). In OBS, add a new Browser source, paste the URL, and set the width and height to match your canvas. The display view is a clean, high-contrast caption board on a dark background, so it works placed full-screen or cropped down to wherever you want it.
- Add a Browser source and paste the display URL.
- Size it to your scene, full-screen or cropped toward the lower third.
- Pick the language in the URL by adding ?lang=es (or any target language code) to the display link.
Adding captions in ProPresenter
ProPresenter handles this the same way through a web block or browser input: paste the display URL, size the region, and send it to your output screen. It's a live page, so it updates on its own. There are no slides to advance and nobody has to sit on a clicker.
If it can show a web page, it can show your captions. There's no plugin to install and nothing to render.
Do a dry run before the room fills up. Start talking, check that the text lands where you want it, and nudge the size until the back row can read it comfortably. One note before you plan a slick lower-third: a transparent, overlay-style caption source with styling controls is on our roadmap, but it hasn't shipped yet. Today's workflow is the full display board.
Free listeners on every plan. Try it yourself.
