vMix NDI (Network Device Interface)

vMix NDI (Network Device Interface) is a feature of the vMix software that allows users to send and receive high-quality, low-latency video and audio streams over a local area network (LAN). NDI is a technology developed by NewTek, which stands for Network Device Interface, and it enables video and audio to be transmitted between NDI-enabled devices and software applications using standard network protocols.

vMix is a popular live video production and streaming software that is commonly used by content creators, broadcasters, event producers, and other professionals for multi-camera productions, live streaming, and video recording. With vMix NDI, users can integrate their vMix setup with other NDI-enabled devices and applications within the same network, expanding the capabilities and flexibility of their live production workflow.

Here’s how vMix NDI works:

  1. NDI Output: vMix can output video and audio sources as NDI streams over the local network. This means that any NDI-enabled device or software on the same network can receive these streams and use them as input sources.
  2. NDI Input: vMix can also receive NDI streams from other NDI-enabled devices or software running on the network. These NDI streams can be used as input sources within vMix, just like any other camera or video source.

Benefits of using vMix NDI:

  1. Flexible Multi-Camera Setup: With vMix NDI, you can easily add more cameras to your production without the need for additional capture cards. NDI allows video sources to be sent over the network, eliminating the physical limitations of traditional HDMI or SDI connections.
  2. Low-Latency Video Transmission: NDI is designed to provide low-latency video transmission, which is essential for live productions where real-time interaction and synchronization are critical.
  3. Simplified Cabling and Setup: NDI reduces the need for extensive cabling and simplifies the setup process, as video and audio signals can be transmitted over standard Ethernet networks.
  4. Integration with NDI Ecosystem: By using vMix NDI, you can integrate vMix with other NDI-enabled devices and software, such as PTZ cameras, graphics systems, media servers, and video playback systems.
  5. Remote Contribution: With NDI, it’s possible to have remote contributors send video and audio feeds over the internet, allowing for decentralized live productions.

It’s important to note that while NDI offers many advantages, its performance depends on the quality and reliability of the network infrastructure. For optimal results, a well-configured Gigabit Ethernet network is recommended when using NDI for high-resolution video production.

Overall, vMix NDI provides users with a powerful and flexible toolset to enhance their live video production capabilities and streamline their workflow by leveraging the benefits of IP-based video transmission.
