NDI®, the innovative network device interface technology from Newtek, on the whole is a game-changer for video production. NDI makes it possible to connect send and receive low-latency, high-quality, video across networks with relative ease. I used to like the “grades” of NDI to the grades of fuel for your car. “Pure” NDI is like premium fuel; It has the best quality, lowest latency, but “costs” the most in terms of bandwidth. It is perfect for “high-performance” networks.
NDI | HX was most like mid-grade fuel, where it easily works for most people and networks. Although NDI | HX still has amazing quality and just a hair more latency (like milliseconds), it takes up much less bandwidth, so it is perfect for almost any network. NDI|HX2 is most like ethanol. It has great performance, a lot of the features that make pure NDI awesome (like embedded metadata) but doesn’t cost you as much bandwidth as NDI.
