For any reasonably professional modern post workflow firewire is completely dead and there’s no new hardware being made. It doesn’t make sense to keep supporting it when there’s all kinds of new standards to implement. If this is something that one really needs (eg. archiving or onlining some old footage) then one should use a different workflow.

Export to prores if you’re on Mac. Or DNxHR if you’re on Windows. That said I don’t know what formats Vegas supports so you’ll need to pick on that works.
