Hello everyone,

Does Vmix work with a DeckLink Quad HDMI Recorder Capture Card, which is built into an external Sonnet's Echo Express SEIII and connected to a Windows PC via Thunderbold 3?

I found this tutorial once:

Thanks to all!

The issue will be the bandwidth.
The DeckLink Quad HDMI Recorder is a x8 card which will be pushing the limits of a Thunderbolt 3 connection (if all ports are connected).
A single Thunderbolt 3 port is generally equivalent to a PCIe 3.0 x4 slot.
Many Thunderbolt enclosure manufacturers are touting connectivity for x8 and x16 cards, however, I think that is somewhat misleading because as I understand it, the maximum connectivity you can get is x8 via a dual port connection (which they don't really disclose).

I hope that puts things in perspective somewhat.
