NDI - Network Device Interface

Previous Next

NDI is an easy way to send and receive high quality, low latency video and audio between supported devices using a standard Gigabit enabled network.

For example you can produce one aspect of your show on one computer and send the output to vMix running on another.

vMix supports both sending and receiving NDI.

Receiving NDI Sources

See NDI / Desktop Capture for more information.

Sending video and audio from vMix using NDI

vMix supports sending a number of different types of output via NDI.
To enable a particular type of output for NDI, it must first be turned on from Settings - External Output


This is the main Output (or "Program") feed and includes the Master stereo audio mix

External 2 (4K and Pro editions)

This is an independent auxiliary output that can be configured to show Output, Preview, MultiView or a particular input.

See External Output for more information.

Cameras / Audio Inputs

Any Camera or Audio inputs currently being used in vMix can also be used remotely via NDI.

Audio Outputs

Master, Headphones, A and B mixes in vMix can all be independently accessed over the network using NDI.

The A and B mixes can be enabled by assigning them to NDI in the dropdown list in Settings - Audio Outputs

and also be checking the Audio Output box in the NDI section under Settings - External Output
