Would this work to connect a Blackmagic UltraStudio Mini Recorder to my late 2016 MacBook Pro?

I will use the Blackmagic to capture footage from a camera via BNC. I just see everyone complaining that this won't work for what they want to do. Here's what it will look like: Camera -> External Monitor in via BNC -> External Monitor out Via BNC -> Blackmagic -> Thunderbolt -> Adapter -> Laptop
