What is NDI?

NDI, or Network Device Interface, is a protocol developed by NewTek that allows video and audio sources to be shared over a local area network in real-time. It enables streaming of high-quality video from cameras, production systems, and more, without the need for physical connections like SDI or HDMI. This technology facilitates a more flexible and scalable broadcasting environment, particularly beneficial for live productions and remote streaming setups.

With NDI, multiple devices can share video feeds over the network, reducing the clutter of cables and offering an efficient way to manage multiple sources. It’s widely used in professional broadcasting environments, allowing for seamless integration with various software and hardware setups, ensuring high-quality output while minimizing latency.

What is OBS?

Open Broadcaster Software, or OBS, is a free and open-source software suite for recording and live streaming. It is widely favored by content creators, gamers, and professional broadcasters because of its versatile features and flexibility. OBS allows users to capture screen activity, webcam footage, and other multimedia inputs, mixing them into a single output stream.

One of the main advantages of OBS is its ability to incorporate various plugins and integrations. By connecting NDI to OBS, users can enhance their streaming capabilities by easily adding high-quality, real-time video feeds from different NDI-compatible devices. This integration makes OBS a powerful tool for professional-quality broadcasts and productions.

How do I install the NDI plugin for OBS?

To install the NDI plugin for OBS, you first need to download the NDI runtime package from the NewTek website. This runtime package contains the necessary components for NDI to function correctly on your system. After downloading, follow the installation prompts to properly set up NDI on your machine.

Once the NDI runtime is installed, you can then download the NDI plugin for OBS from the official OBS website or GitHub repository. After downloading the plugin, extract the files and copy them into the OBS Studio installation directory, specifically into the ‘obs-plugins’ folder. Restart OBS, and you should find NDI options available in your software.

How can I add an NDI source to OBS?

To add an NDI source in OBS, launch the software and make sure your NDI device is connected to the same network as your computer. In OBS, right-click in the ‘Sources’ panel, then select ‘Add’ followed by ‘NDI Source’ from the dropdown menu. This action opens a window where you can name your new source for easy reference.

After naming the source, you will see a dropdown list of available NDI feeds detected on your network. Choose the desired NDI source you want to add. Make sure to configure settings such as audio options and video quality, if necessary, before clicking ‘OK’ to finalize the addition. Your NDI source will now appear in the Sources list, ready for use in your broadcast.

What are the system requirements for using NDI with OBS?

To use NDI with OBS, your system should meet certain minimum requirements to ensure smooth operation. Generally, you will need a modern processor (such as an Intel Core i5 or equivalent), at least 8GB of RAM, and a good graphics card to handle video processing tasks. Furthermore, a gigabit Ethernet connection is strongly recommended to support the high bandwidth requirements of NDI.

Additionally, keep your operating system up to date. NDI compatibility may vary depending on the version of your OS, so it’s advisable to use the latest version of Windows or macOS to minimize compatibility issues. Ensure you have enough storage space for your recordings, and a stable internet connection if you plan to stream online.

Can I use multiple NDI sources in OBS?

Yes, you can use multiple NDI sources in OBS simultaneously. This feature is particularly advantageous for professional broadcasts where several camera angles or graphics need to be integrated into the stream. Each NDI source can be added separately following the process of right-clicking in the ‘Sources’ panel and selecting ‘NDI Source’ for each additional device.

When using multiple NDI sources, monitor your system’s performance. Streaming multiple high-quality video feeds can be resource-intensive, and it’s essential to ensure that your hardware can handle the load. You may need to adjust settings such as resolution and frame rate to maintain smooth performance during your broadcasts.

What should I do if my NDI source is not showing up in OBS?

If your NDI source is not appearing in OBS, the first step is to verify that your NDI device is correctly connected to the same network as your broadcasting computer. Ensure both devices are on the same IP subnet, as NDI sources can only communicate within the same network. Restarting your NDI device and OBS can sometimes resolve connectivity issues.

If the problem persists, check the NDI runtime installation to confirm it was completed successfully and that your system meets the required specifications. Additionally, some firewalls or antivirus programs may block NDI traffic. Temporarily disable such applications to determine if they affect detection and re-enable them once you’ve confirmed functionality.

Does using NDI with OBS incur any latency?

Using NDI with OBS typically incurs minimal latency, making it a viable choice for real-time broadcasting applications. The latency largely depends on your network speed, the quality of the NDI streams, as well as the performance of your hardware. In optimal conditions and with a robust gigabit network, the latency is often imperceptible to viewers.

However, if you experience noticeable latency, consider troubleshooting your network setup. Ensuring a wired connection instead of relying on Wi-Fi can significantly reduce lag. Additionally, tweaking NDI settings in OBS can help to lower latency further by adjusting bandwidth usage or selecting lower resolution and frame rates suitable to your broadcast needs.
