Stream with vMix
Connect vMix in a couple of minutes: two values to paste and a few settings to check.
vMix sends your video to Onzsa. It needs two things from us: where to send it, and a private key that proves it’s you. Your Onzsa server and stream key are in Settings → Channel under “Stream key”, and in Creator studio once you have set up a broadcast.
Connect vMix
- Click the gear icon next to the "Stream" button at the bottom of vMix.
- Set "Destination" to "Custom RTMP Server" — that is vMix’s name for a server it does not list.
- Paste your Onzsa server into "URL".
- Paste your stream key into "Stream Name or Key".
In vMix, the server goes in “URL” and the key in “Stream Name or Key”. Treat the key like a password: anyone who has it can stream to your channel. If it ever leaks, replace it in Settings → Channel — the old one stops working straight away.
Pick settings for your internet
Your upload speed decides how sharp your stream can be. The connection check in Creator studio measures it and fills these steps in for you. The steps below use 1080p at 60 fps; use the table to pick the row that fits.
- Click the gear next to "Quality" and set "Video Bit Rate" to 6000 kbps and "Audio Bit Rate" to 160 kbps.
- Set the size to 1920x1080. If a keyframe setting is shown, set it to 2 seconds.
- Make sure vMix itself is running at 60 frames per second (Settings → "General").
