Vizrt Group - NDI


Network Device Interface (NDI®) is a free standard originally developed by NewTek to enable video-compatible products to communicate, deliver and receive broadcast quality video in a high quality, low latency manner that is frame-accurate and suitable for switching in a live production environment.

NDI is now a brand under the Vizrt Group which is adopted and integrated into products by hundreds of companies, in development with thousands and readily accessible to millions of people. NDI is the most widely adopted and used IP standard in the world and presents compelling new opportunities for video in any workflow or environment.

At NAB 2019, NewTek and Vizrt unveiled NDI 4 with an array of new capabilities merging the fields of live video and post production by including the ability to record unlimited NDI video channels for true multi-camera editing with full synchronization with any video or audio format, 4K and beyond included. Recording is limited only by disk and network performance.
Recordings are time-stamped and time base corrected; any number of channels on any number of machines are in full harmony. Video editing from a variety of sources, from the same event, can be edited simultaneously making multi-cam editing truly accessible for the first time. NDI recording supports alpha channel, any number of audio channels, and works with 16bpp sources at full precision.

NDI gives users more flexibility than ever thought possible. NDI devices are connected with each other and automatically discovered on the network. NDI 4’s other increased efficiencies include improvements in video quality without an increase in bit-rate, support for a 16 bit video path, and many more input and output colour formats.

NDI 4 provides support for a discovery server allowing for the use of a server or the cloud to coordinate and connect all sources. Also included an NDI | HX which is now fully integrated into the NDI Embedded SDK. Additionally, support for Epic Games Unreal Engine in NDI 4 makes it possible for apps created in Unreal to appear as NDI sources.

In the past three years, NDI has become the way video producers, from game streamers to tier one broadcasters, work. NDI can encode, transmit and receive many streams of high quality, low latency, frame-accurate video and audio in real time. This benefits any network-connected video device, including cameras,
