How vMix + StreamTranslate works together

vMix is the pro-grade broadcast platform of choice for IRL streamers, esports productions, and conference webcasts. StreamTranslate adds a real-time translation layer on top of any vMix scene by sitting inside the Web Browser Input — the same way you'd add a lower-third or scoreboard graphic.

Speech-to-text is handled by Deepgram nova-2 for English, German, Spanish, French, Portuguese, Italian, Polish, Russian and Dutch; nova-3 covers Mandarin, Cantonese, Japanese, Korean, Arabic, and Hindi. A 7-provider translation race (GoogleFree, MyMemory, Libre, Lecto, plus Azure, DeepL, and Google paid as fallback) returns the best translation in under 500ms.

Because everything runs in the cloud and renders as a transparent browser layer, vMix doesn't pay any CPU cost — even on 4K productions. The translated subtitles are baked into your output stream before it goes to Twitch, YouTube, Restream, or any other destination.

Setup steps

In vMix, click Add Input → Web Browser → paste your StreamTranslate overlay URL → set transparency to On → resize and position the layer over your scene. Go live. That's it.

Frequently asked questions

Does StreamTranslate work with vMix Pro and vMix HD?
Yes. Any vMix license tier that supports Web Browser Input (Basic HD and up) works with StreamTranslate. The integration is identical across tiers.
Will subtitles add latency to my vMix output?
No noticeable latency. The browser layer renders in real time inside vMix, so subtitle frames are composed alongside your video without any added encoder delay.
Can I use StreamTranslate with vMix Call participants?
Yes — StreamTranslate transcribes whatever audio your mic captures in vMix, so multi-mic setups (vMix Call guests, in-room cameras, headset mics) are all picked up if routed through the program audio bus.
