How do i connect capture to ndi prieview in vista

hello, i’ve recently learned roughly about ndi preview and it’s capabilities. the issue is i can’t figure out how to connect capture to ndi preview. ive tried looking at user manuals, youtube, and the vista fourms but i can’t find anything. if somone could provide a youtube video or step by step instructions on how to connect it. that would be appriciated. thank you!

Does Capture explicitly support NDI output from its visualization?

My understanding is that it does not use NDI in this way.
It does however support NDI for streaming in video to represent video walls etc.

you could use NDI tools to test the NDI input on your system.
You could even possibly use some desktop capture of your capture system and stream that into Vista that way.
