Destination
Found under your Twitch dashboard → Settings → Stream → Stream Key. This is the same key OBS uses — no OAuth needed to go live.
Optional: show connected channel name
Encoding
Changing this rescales every existing layer in every scene to fit, so nothing shifts out of frame.
A cap, not a guarantee — your connection can still push it lower under real congestion, but this stops the encoder from chasing a higher number than it should and tells it to hold resolution steady and drop framerate first if it has to give something up. 4500–6000 kbps is typical for 1080p30 on Twitch; go lower if your upload can't sustain that. Applies immediately if you're already live.
Tab / window / screen
Tick "share tab audio" in the picker if you want that audio in the mix.
Camera & microphone
Additional audio (co-host / guest)
Google Meet or vdo.ninja: put it in its own tab, share that tab, and tick "share tab audio". Discord or Teams: browsers can't capture a single app's audio, so share "Entire screen" and tick "share system audio" instead — or route the app to a virtual audio cable and pick it as a device below.
Mixed straight into the stream but not sent to your speakers, to avoid an echo — monitor it in the source app or your headset.
