How Ecamm Live + StreamTranslate works together

Ecamm Live is the Mac-native streaming app of choice for podcasters, course creators, and Mac-first content creators. Its Web Widget Overlay feature accepts arbitrary URLs — including StreamTranslate's real-time translation overlay.

Podcasters and webinar hosts especially benefit from live translation because their audiences are often more globally distributed than gaming streamers. Spanish, Portuguese, French, German, Japanese, and Mandarin are the most-requested target languages from Mac creators.

Ecamm Live's Web Widget Overlay has an interactive mode toggle, which StreamTranslate works with — though typically you'd leave it off since subtitle overlays don't need user interaction. Set the overlay to 1920x1080 transparent and position it where you want subtitles.

Setup steps

In Ecamm Live, open the Overlay panel → + → Web Widget. Paste your StreamTranslate overlay URL. Set the size to 1920x1080, transparency on, and position at the bottom of your scene. Save.

Frequently asked questions

Does it work with multiple cameras in Ecamm?
Yes — the overlay sits above all video layers in Ecamm's compositor, so it renders consistently regardless of which camera or scene you switch to.
Will it work with Ecamm Live's interview features?
Yes — StreamTranslate transcribes whatever audio is on your local mic. For multi-speaker interviews with guests on Zoom/Ecamm Interview, currently only the host's mic audio is transcribed by StreamTranslate.
Is StreamTranslate available without OBS for Mac users?
Yes — StreamTranslate is entirely browser-based and works in any Mac streaming app that supports browser sources or web overlays, including Ecamm Live, mimoLive, and OBS for Mac.
