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?
The general consensus is that any operating systems after Mojave break compatibility with Mini DV or they're not as reliable as older versions of Mac OS. LifeFlix is in active development, and it even works with the new M1 chip.
Alternatively, if you have access to a Mac with Mojave or earlier, or you can boot the Macbook Pro off a portable SSD running Mojave, you can use Apple's AVCVideoCap: https://www.cuttingcords.com/s/AVCVideoCap.zip
