OBS NDI Output Network Requirements?

Hey y'all,

I noticed my OBS on my NDI output computer is using about 55-60 Mbps. The computer receiving it is only using ~9 Mbps.

I wanted to use NDI as a solution for a project I'm doing where I have some PCs where Streamers can play games together in person, and then I would be able to pull all their streams into my own stream and switch between them. So I would just have them stream with their own stream collection, but then turn on NDI Output on Program for each of them. I want to know the network requirements per setup I should consider. How can I add that up?

I did want to point out, where I am testing this (not the workplace) as a proof of concept, one NDI's upload is much higher than a speedtest with my ISP says. I assume that is because NDI is all local, which is why I am interested in finding out how I can roughly calculate how much I would need per NDI (and Stream to Twitch/Youtube), since if a speedtest doesn't show relevant data for that I need to know.

Thank you!

I'd recommend looking into NDI vs NDI HX, and especially NDI Tools (free) from NewTek.
My 1080p60 NDI PoE PTZ camera sends a HX stream of around 25-30mb/s, received by my OBS Studio PC. Beware (in regards to network bandwidth calculations) configs that enable sending video traffic to multiple destinations

I believe our camera's are going to be SDI into a switcher, but this is a great call on the network stuff thank you!

For NDI Tools, is that better than just using the DistroAV plugin for sending or receiving? I will look into it.
