vMix is a professional live production and streaming solution for Windows. It supports multi-camera switching, graphics overlays, and simultaneous output to multiple destinations. This guide covers connecting vMix to WAVE via RTMP, SRT, and NDI, configuring multi-bitrate outputs, and resolving common issues.

Prerequisites

RTMP output setup

{% stepper %} {% step title=“Open streaming settings” %} In vMix, click the Stream button in the bottom toolbar, or navigate to the gear icon and select Streaming. {% /step %}

{% step title=“Add a streaming destination” %} Click Add to create a new streaming destination. Select Custom RTMP Server from the provider list. {% /step %}

{% step title=“Enter your WAVE credentials” %} Configure the destination with the following settings:

{% step title=“Configure the quality profile” %} Click the Quality dropdown and select Custom:

{% step title=“Start streaming” %} Click Start on the streaming destination. The status indicator turns green when the connection is established. Verify in the WAVE dashboard that your stream shows as Live. {% /step %} {% /stepper %}

{% callout type=“tip” title=“RTMPS for encrypted streams” %} To use encrypted RTMP, change the URL to rtmps://ingest.wave.online:443/live. vMix 25+ supports RTMPS natively. This is recommended for content that requires encryption in transit. {% /callout %}

SRT caller setup

SRT provides lower latency and better error resilience than RTMP. vMix supports SRT in both caller and listener modes.

{% stepper %} {% step title=“Open Output settings” %} Click the gear icon in the vMix toolbar and navigate to Output / NDI / SRT. {% /step %}

{% step title=“Select SRT Output” %} In the Output section, click the dropdown and select SRT. Set the Mode to Caller (vMix initiates the connection to WAVE). {% /step %}

{% step title=“Configure encryption (optional)” %} If your WAVE stream has SRT encryption enabled:

{% callout type=“warning” title=“Passphrase must match exactly” %} The passphrase is case-sensitive and must match the WAVE stream configuration character for character. A mismatch causes a silent handshake failure. {% /callout %} {% /step %}

{% step title=“Start the SRT output” %} Click Start on the SRT output. Monitor the connection status in vMix — a green indicator means the connection is active. Verify in the WAVE dashboard. {% /step %} {% /stepper %}

NDI output to WAVE

If your production facility runs NDI on the local network, you can route NDI sources through WAVE for cloud distribution.

{% callout type=“info” title=“NDI requires WAVE Synapse” %} NDI-to-cloud routing requires the WAVE Synapse device management module. See the Synapse documentation for setup instructions. {% /callout %}

{% stepper %} {% step title=“Enable NDI output in vMix” %} Navigate to Settings > Output / NDI / SRT and enable NDI Output. Choose which output (Program, Preview, or a specific input) to publish as an NDI source. {% /step %}

{% step title=“Discover the NDI source in WAVE Synapse” %} In the WAVE dashboard, navigate to Synapse > Devices and run a discovery scan. Your vMix NDI output should appear as a discovered source on the network. {% /step %}

{% step title=“Create a route from NDI to cloud” %} In Synapse, create a route from the vMix NDI source to your WAVE stream channel. Synapse handles the protocol conversion from NDI to WAVE’s cloud ingest automatically. {% /step %} {% /stepper %}

Multi-bitrate configuration

vMix can stream to multiple destinations simultaneously, which is useful for sending different quality tiers to WAVE or streaming to WAVE alongside other platforms.

{% stepper %} {% step title=“Add multiple streaming destinations” %} In the Streaming settings, click Add to create additional destinations. You can have up to 3 simultaneous streaming outputs in vMix (depending on your edition). {% /step %}

{% step title=“Configure each destination” %} Set each destination to stream to WAVE with a different quality profile:

Each destination requires a separate WAVE stream channel with its own ingest URL and stream key. {% /step %}

{% step title=“Start all outputs” %} Click Start All or start each destination individually. Monitor all connections in the vMix streaming panel.

{% callout type=“tip” title=“WAVE handles adaptive bitrate automatically” %} If you only need adaptive bitrate for viewers, you do not need to send multiple bitrates from vMix. WAVE transcodes your single ingest stream into multiple quality tiers automatically. Multi-bitrate from vMix is useful when you want precise control over each tier’s encoding settings. {% /callout %} {% /step %} {% /stepper %}

Troubleshooting

vMix shows “Connection failed” or “Timeout”

Stream connects but has poor quality
