NDI allows multiple video systems to identify and communicate with one another over IP, and to encode, transmit and receive many streams of high quality, low latency, frame-accurate video and audio in realtime.

What does the NDI do?
Network Device Interface (NDI) is a royalty-free software standard developed by NewTek to enable video-compatible products to communicate, deliver, and receive high-definition video over a computer network in a high-quality, low-latency manner that is frame accurate and suitable for switching in a live production
How does NDI 5 work?
NDI 5 offers an all-new Adobe Creative Cloud plugin which allows audio output both to the soundcard and the NDI output, meaning users can hear the very same audio as is going out to NDI, providing a full editor workflow for Adobe Video Production.
Can NDI work over Internet?
Cloud for NDI provides NDI service discovery forwarding across wide area networks (including the internet), and also offers multiple transport modes to suit available bandwidth between sites.
How do I set up NDI?
First of all make sure you have OBS Studio installed.
- Download the NewTek NDI plugin for OBS Studio. You can download the plugin from GitHub here or from the OBS Studio plugin directory here.
- Download and install the Camera for OBS Studio iOS App.
- Configure the device output.
- Add the NDI input into your OBS Studio Scene.
Is NDI Unicast or Multicast?
Recommended dedicated bandwidth for NDI and NDI|HX:
NDI relies on mDNS (multicast Domain Name System) to create a zero configuration environment. Unlike other video over IP based protocols, there is no need to remember IP addresses, host names, or port numbers.
How do teams use NDI?
In the Teams admin center, go to Meeting policies > Audio & video and select Allow NDI Streaming. After this change has populated, the end user must turn on local streaming for their specific client from Settings > Permissions. For more information, see Broadcasting audio and video from Teams.
What is an NDI signal?
NDI is a network protocol that enables audio, video, and metadata signals to be sent over standard networks in real-time. NDI is bidirectional, low latency, and can transmit video up to 4K and beyond. It is used in some of the largest broadcast environments in the world and many pro AV integrations.
How stable is NDI?
The peak signal-to-noise ratio (PSNR) of the NDI codec exceeds 70dB for typical video content. Uniquely, and importantly, NDI is the first ever codec to provide multi-generational stability. This means that once a video signal is compressed, there is no further loss.
What is NDI in AV?
NDI is video production over IP that you can use now on standard gigabit IP networks. Traditional control rooms and video productions utilized multiple paths, proprietary hardware, and distribution cores. With NDI, the network is your distribution and all video sources are available to all video destinations.
What is OBS NDI?
NDI stands for Network Device Interface, and it’s the protocol developed by NewTek for broadcasting high quality video and audio over an internal gigabit network.Use software like OBS and receive video and audio from other computers to record or stream. Install it on your mobile phone and use them as extra cameras.
How much bandwidth does NDI use?
For 1080p60 streams, Full bandwidth NDI® utilizes about ~150Mbps with latencies of ~16ms where HX can use anything between 1~50Mbps with latencies ranging between 80-200ms depending on the equipment used.
How many sources does NDI have?
vMix and NDI – what are the system requirements? The number of simultaneous sources that can be sent and received will depend on the speed of the processor. A modest 3 Ghz PC can generally receive 4 full HD NDI sources (or more) at the same time.
What is NDI 4 Discovery Server?
NDI® Discovery Server Print
Using the NDI® Discovery Server may help mitigate certain issues related to mDNS traffic on computer networks.The NDI® Discovery Server is a lightweight application that can run on your computer. You will need to know the IP address of the computer on which it is running.
Is NDI point to point?
NDI enables bi-directional video and audio over IP.Many methods comprise linear, one-way, point-to-point distribution of a single video output signal over IP to a single destination. NDI workflows permits multi-directional, two-way signal transmission over IP, to and/or from any NDI®-enabled device on your network.
Does NDI carry audio?
As well as video data, each NDI stream can carry up to 16 channels of embedded floating point audio and bi-directional data, meaning you can use NDI to control tally lights, PTZ cameras and the like all over one network connection.
Can you use NDI without Internet?
Now your camera is activated and able to deliver NDI video without an internet connection. The takeaway is that you should be prepared to spend some time setting things up initially with any of the new network-reliant tools.
What is the difference between SDI and NDI?
What is the difference between NDI and SDI? SDI is a technology that has been around for decades.NDI is a much newer technology that uses the latest video compression methods to make sending and receiving high-quality video possible over standard computer networks.
Is NDI compressed?
NDI uses compression to enable transmission of video streams in the network. According to NewTek, NDI is one of the most efficient codecs in existence: “NDI achieves significantly better compression than the majority of codecs that have been accepted for professional broadcast use.
What port does NDI use?
port 5960
The NDI messaging server uses port 5960. Subsequent ports required by the sending device to accommodate the total number of NDI video streams it supports are assigned in ascending order. Ports must be open through the entire path between network subnets.
Does NDI need mDNS?
As default, NDI utilizes mDNS (multicast Domain Name System)1 to create the zeroconfiguration environment for discovery. This service sends an IP multicast message that asks the host to identify itself.
