Local Network Streaming

Local Network Streaming using NDI (recommended method)

NDI® is a technology that makes it easy to send and receive multiple channels of broadcast quality, low latency video over an existing Gigabit Ethernet Network. (see more on our NDI page)

NDI is the recommended method to use for local network streaming due to its quality and low latency.

Step 1

In vMix, select the Settings button at the top right corner. Then choose the Outputs/NDI tab. Select the NDI button positioned to the right of Output 1 so it is green and says NDI On. This will make Output 1 available as a source over the network via NDI. Click OK to save.

Step 2

For each computer on the local network that will be watching the vMix output (or local network stream), download and install the free Newtek NDI Tools pack available at the following link:


This tool pack contains the NDI Studio Monitor program that will allow you to watch the vMix output being sent over NDI.

Step 3

Make sure any computers that want to watch the vMix output are on the same local network as the vMix computer. Open the NDI Studo Monitor program that was installed in Step 2.

Once opened, hover your cursor over the top left until you see the hamburger (3 lines) menu.

A menu will then appear. This menu should show the computer name of the vMix computer. Under that it should then allow you to select vMix - Output 1.

It should then start playing the video and audio output coming out of vMix.


Local Network Streaming using WMV

vMix also supports streaming to multiple users on the same network via WMV Streaming
To setup WMV streaming follow the steps below:
1. Click the cog icon (setup) next to Record at the bottom of the main vMix window
2. Select the WMV Streaming tab
3. We recommend 640x360 as the size (resolution) and 1500000 as the bit rate. You can increase the bitrate and resolution as required.
4. Click OK to save your settings
5. Click the Record button to begin streaming
The stream will now be accessible via Windows Media Player or VLC on the local network by typing in the following URL:
x.x.x.x will need to be replaced with the IP address of the computer running vMix.
As WMV Streaming uses the vMix recording feature, if you want to keep a recording of the stream as well you can use the External output in vMix
and connect it to Microsoft Expression Encoder, a separate free application that can stream the output of vMix in the same way as WMV Streaming
To use Expression Encoder, first setup your External Output settings in vMix Settings and click the External button at the bottom of the main vMix window.
Then in Expression Encode select vMix Video as the video source and vMix Audio as the audio source when setting up your stream.
