To import your video you'll need a firewire connection.
If your camera doesn't have a Firewire (usually FW400) port, it will likely have a Composite or Component out. To deal with that you'll need a Composite or Component to DV converter. The converter must output Firewire. (Something like the Canopus ADVC-300)
If your computer doesn't have a Firewire (FW) port (and the new ones do not) but has a Thunderbolt (TB) port, you'll need a TB 2 to FW 800 dongle then a FW 800 to 400 adapter. If you have a really new MacBook, you'll also need a TB 3 to TB 2 adapter.
The most straightforward connection chain looks like this: Camcorder>FW 400 out>FW 400 to 800 converter>FW 800 to TB 2 dongle>then either TB 2 in or TBt 2 to TB 3 adapter. The TB3 uses the same plug as the USB-C form.
Worst case chain looks like this: Camcorder > Composite or Component out > Analog to DV converter (eg Canopus ADVC-300) > FW 400 out to FW 800 converter > FW 800 to TB 2 converter > TB2 to TB3 converter.
The caveat is: There is no guarantee any of this will work. In the "ye olden days" of tape based DV, these forums were FILLED with the struggles of people trying to get their camcorders to talk with computers. And ... keep in mind this was the time when the standard connection was a straight forward FW 400 cable.
Your best bet maybe to find a video transfer service - sometimes public access channels have legacy equipment - and pay them to do it. It will likely be cheaper than trying to do it yourself.
Good luck
