How to use NDI Cameras in OBS

Integrating NDI (Network Device Interface) cameras with OBS Studio allows for efficient, high-quality video production over a local network. Here's a comprehensive guide to setting up and optimizing NDI cameras within OBS Studio.

Understanding NDI and Its Benefits

NDI is a protocol developed by NewTek that facilitates the transmission of high-definition video and audio over standard IP networks. By leveraging NDI, content creators can connect multiple video sources, such as cameras and computers, without the need for traditional video cables. This flexibility simplifies setups, reduces costs, and enhances scalability in live productions.

Setting Up NDI Cameras with OBS Studio

  1. Install the NDI Runtime:
    • Begin by downloading and installing the latest NDI Runtime from NewTek's official website. This ensures your system can handle NDI streams effectively.
  2. Install the OBS-NDI Plugin:
    • To enable NDI functionality within OBS Studio, you'll need the OBS-NDI plugin.
    • Download the appropriate installer for your operating system from the OBS-NDI plugin release page.
    • Run the installer and follow the on-screen prompts. Ensure that the NDI Runtime installation option is selected if it's not already installed.
  3. Verify Plugin Installation:
    • After installation, restart your computer.
    • Open OBS Studio.
    • Navigate to the "Tools" menu; the presence of "NDI Output Settings" confirms a successful plugin installation.
  4. Add NDI Sources in OBS:
    • Ensure your NDI cameras are connected to the same local network as your OBS system.
    • In OBS Studio, click the "+" button in the "Sources" panel and select "NDI Source."
    • In the properties window, choose your NDI camera from the "Source Name" dropdown menu.
    • Adjust settings as needed and click "OK" to add the NDI camera to your scene.

Optimizing Your NDI Setup

  • Network Considerations: For optimal performance, use a wired Gigabit Ethernet connection. While NDI can function over Wi-Fi, a wired setup minimizes latency and ensures stable video streams.

  • NDI Filters in OBS: The OBS-NDI plugin offers a "Dedicated NDI Output" filter. This feature allows you to output specific sources or scenes as NDI streams, providing flexibility in complex productions.

Advanced Applications

  • Mobile Device Integration: Transform your smartphone into an NDI camera using apps like NDI's HX Camera. This setup allows for wireless video capture, expanding your production capabilities without additional hardware.

  • Multi-Computer Setups: Utilize NDI to connect multiple computers running OBS Studio. This configuration is beneficial for distributing processing loads, such as handling gaming on one system while streaming from another.

Conclusion

Integrating NDI cameras with OBS Studio revolutionizes the way live productions are conducted, offering flexibility and efficiency. By following the steps outlined above and considering network optimizations, you can harness the full potential of NDI technology in your OBS workflows.
