NDI allowed us to send and receive 4K over the local network and break up some of our production requirements. You select which window or desktop you want as NDI stream in Streamlabs OBS rather than selecting in the application which to use. There is also vMix Desktop capture available from the creators of vMix that creates an NDI stream of every single open window and desktop available. This was then uploaded to YouTube so that viewers could watch the show in it’s full 4K glory. Create NDI stream with vMix Desktop Capture.

We were able to stream flawlessly to YouTube in Full HD (1920×1080) and also record the show as a 4K Mp4 at 25mbit. The second machine was an i7 6700K with a NVIDIA GTX1060 and handled it all with ease.
Vmix ndi 1080p#
This second computer was set up to accept the NDI output from the vMix Studio PC and then to stream in 1080p to YouTube AND record in 4K.
We then set up a shortcut on the 2nd vMix computer to start streaming and recording when the production started. As vMix is able to send and receive NDI video, the computers were then set up to send and receive the production output via NDI. 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 environment. As we decided to take our production up to 4K we took the opportunity to test out the possibility of sending the 4K output to another computer, all using NDI! We have both computers set up on the local gigabit network and vMix is installed on both machines. We produce record and stream via our studio PC with 4 HD cameras. Typically our productions are done all on the one vMix PC. This PC then streamed the show to YouTube in HD whilst recording a 4K copy to be uploaded later. Everything was produced on our studio PC and then the recording and streaming were sent via NDI to one of our other testing PCs. The latest vMix Fun Time Live Show video was produced live in 4K.
