So, I have Nikon D3200 that was gifted to me a few years ago, camera works great.
I've gotten into streaming since getting Fibre to the home (1000Mbps/750Mbps) and people have requested I get a cam feed.

Every bit of info I can find says that the D3200 can be captured via USB direct from camera to computer, using Vmix. Even on Nikon's website, they say this software and another one (which doesn't work as it excludes the 3200 for some reason).

Examples:

"Option 1: USB Plug-n-Play

Quick & Easy

This method is ideal for those seeking a high quality video stream with the simplest setup and no additional hardware.

Connect your Nikon camera to your computer using the USB cable that was included with your camera.

Download and install any third-party conferencing/broadcasting software that is compatible with both your Nikon camera and your computer’s operating system.

Software like Ecamm Live (Mac), Vmix (PC), SparkoCam (PC) have compatibility with select Nikon cameras via USB and can seamlessly connect to streaming applications like Zoom, WebEx, Twitch, Facebook Live and others."

Etc.

And if it does work, is it just the crappy live preview that you get that's like 640x480? Or is it the full 24 Megapixel rez?
