Video Switcher (hardware)

I am looking to maybe get something like this… : Feelworld Live PRO L1 Multiformat Video Mixer Switcher 2 Inch LCD Display 4X HDMI Input USB3.0 Live Streaming/Camera Production/Live Broadcast (with USB Cable + Adapter) : Electronics

Does anyone know if ManyCam would support something like this?

I got one. It works well with ManyCam. The USB cable didn’t work well. I used a USB to HDMI converter from Amazon for about $20. This unit used less processing power on my Mac than having individual cameras plugged directly into my Mac.

Thanks! Appreciate the confirmation. I am getting one
