I have to import 40 tapes in mini DV and HI8 tapes from Sony HDR-HC3 and TRV350 cameras. I need digital formats. Both cameras have 4 pin IEEE 1394 firewire output ports. Unfortunately, I got rid of all my old laptops with firewire and don't feel like buying another old laptop with windows 7. So I thought to buy a 4 pin to 9 pin firewire adapter or wire. Then connect to an apple thunderbolt 2 adapter turning the 9 pin firewire into a thunderbolt 2 connection. Then connecting the previous to a thunderbolt 2 to thunderbolt 3 (USB-C) connection. Then plugging this into my windows 10 USB-C. Anyone have experience if this will work?
