Uses for NDI

Hello Everybody!


Today we’re going to be talking about Network Direct Interface, or NDI for short. If you’ve been reading about NewTek products such as the Tricaster or the Input Module then you have probably seen this acronym before. Today we’re going to be talking a little bit about what NDI is and why it’s a beneficial tool to any live production studio.


The current standard for in the video world today is SDI, which operates on a one way path and requires a cable or circuit that passes one video signal. SDI does allow higher bandwidth, however as a studio grows and more and more inputs are required for camera and audio equipment the number of cables required for these inputs also increases. Eventually you’ll have so many cables that it will become increasingly difficult to manage all of them in addition to turning your studio turning into a cluttered and unsightly mess.

SDI requires a cable for each input.


NDI alleviates that issue by operating on an already existing network that can connect to your equipment.


NDI can operate on an already existing network that is passing information across it. This means that it doesn’t require too much dedicated equipment to make it work. While SDI would require multiple cables and inputs added to your Tricaster, NDI instead would link up with the inputs through the network. NDI can even be used in addition to SDI, allowing additional inputs to be used that couldn’t be accessed by SDI alone. For example the Tricaster 8000 has eight camera inputs on it, but by utilizing NDI you could link up an additional four inputs to the Tricaster to bring it up to 12.



There’s also a ton of NewTek products that are compatible with NDI and can enhance the quality of your productions! Do you want to add a graphic straight from Adobe Premiere on your laptop? Download NDI for Adobe Creative Cloud which is part of a free tool kit download on
NDI is intended work on every modern network, which means there is little holding you back.
