Stream on Twitch

Use Facecast as your live face source on Twitch via OBS Studio — the same browser-tab + Window Capture pattern, then OBS handles the RTMP push to Twitch.

Requirements

→Active Facecast session (trial / Day Pass / Pro)
→OBS Studio (free, obsproject.com)
→Twitch account + Stream Key

Start a Facecast session in your browser

Open facecast.org/faceswap, allow camera access, pick a face, and confirm the swap is rendering smoothly. Leave this tab open — it is your video source.

Capture the browser tab in OBS

In OBS, add a new Window Capture source and select the browser tab running the swap. Crop the OBS scene to the video area only (not the full browser chrome).

Tip: Use a dedicated browser window with the tab pinned so the OBS capture doesn't drift if you switch tabs.

Get your Twitch Stream Key

Twitch Dashboard → Settings → Stream → Primary Stream Key. Copy it. Treat it like a password — anyone with this key can stream as you.

Tip: Pick a Twitch ingest server closest to your physical location for the lowest latency.

Configure OBS to push to Twitch

OBS → Settings → Stream → Service: Twitch → paste your Stream Key. Click Apply, then OBS → Start Streaming.

Go Live and engage

Open your Twitch channel page or Stream Manager to confirm you're live. Switch the source face mid-stream for surprise moments — viewers love it.
