iMovie does not see my Mini DV tapes

I am trying to import Mini DV on my 2020 MacBook Pro. My camera is a 22 year old Sony HDR-HC7E. I have a 400 to 800 Firewire cable, and 2 Apple adaptors - Firewire 800 to Thunderbolt 2 and Thunderbolt 2 to 3. I have tried using iMovie which sees that a camera is plugged in but cannot import the video. I have also tried LifeFlix and it did not import the video either. My Sony camcorder is not on the list of camcorders supported by iMovie. Is there another software I could use to capture my videos?
