I'm looking to build a vmix PC with about 30 input sdi with w790 mainboard, Intel Xeon W3400/2400 and GPU Quadro A5000. I don't know if vmix has support to optimize for that hardware?

Or can someone suggest me how to build a PC vmix around 24-30 inputs (x3-4 Decklink Quad)

W790 WS

You won't like this answer (and as a vMix enthusiast I hate to say it) but that many hardware inputs isn't well suited for vMix.

And it's not vMix's fault either- general purpose PC hardware just doesn't fit this use case well. I run a 16 input machine with an A6000 and it chokes sometimes. (This is due largely to my build being a dual socket so NUMA / the CPU interconnect fabric is being largely tapped out.)

Every few years Netflix releases slides about how they improve their architecture to work better on multi CPU machines. It's worth a glance:

If you were to try and do it, you've picked the right CPU (super high PCIe lane count).

Maybe Blackmagic Videohub can be used in your case?

It's hard for me to imagine a scenario where 30 SDI inputs would be needed in vMix for live streaming :)
