Starting with version 1.54 Nobe Display supports NDI® streaming. This means you can share your video signal with anyone in the world using any 3rd party streaming application using the built-in system video input device (webcam).
First step is to download and install NDI Tools from NewTek:
Once you have Nobe Display installed, start DaVinci Resolve, go to the Timeline Node and apply Nobe Display Connect OpenFX plugin:
Next, open Nobe Display either from /Applications in macOS, from the Desktop shortcut or directly from the OpenFX inspector by pressing "Open Display" button and hit "Connect" button in Nobe Display application:
Once you do that, you should be able to see the live preview from DaVinci in Nobe Display window. Go to Options / NDI® to see the current status:
Now, launch NDI® Virtual Input app (Applications folder on macOS or menu start on WIndows) and find our Nobe Display Connect source in the Sources menu:
From now on you should be able to see a new video device in your system and in the apps compatible with the system video input device (Zoom, OBS, Skype*, etc)
