Ok, found my old Sony PC5e miniDv camera circa 2000 and would like to get the footage from all my tapes onto my 2016 iMac. The camera socket connects to 4 pin male 1394 FireWire. I have tried a FireWire to USB cable and it doesn’t work. Before I buy more cables and connectors that don’t work has anyone had any experiences? I was thinking maybe the Apple thunderbolt to FireWire 800 then another attachment to get it down to 400 but maybe that won’t work either? Thanks!
