That all depends on the camcorder + what connections it has. If you see yellow, red and white, that means it’s composite. So you’d need a composite video cable to a composite-female to usb adapter… then if needed, a usb-c to usb-a female adapter.you’d also need a copy of the video capture software.. obs studio.. available https://obsproject.com/
unless your mini dvd uses one of those slightly strange Sony formats.. you should be good to go. Put the camcorder into playback mode, ensure it’s plugged into a power supply, shut down your Mac, make the connection between camcorder + mac, start up your mac, get obs studio going, ensure there’s a mini dvd in there, then press play on the camcordef and that should be it
good luck to you
