FCPX accepts VX footage. I use an old macbook with a lightning to firewire cable to import the footage (I think the clips are uncompressed .mov files) then wetransfer it to myself and DL onto my modern macbook, which doesn’t have the requisite port.
Never had any issues with MiniDV footage on there. I feel like FCPX used to get shit on a lot in the skate editing world, but it can do just about whatever you want it to do. It’s not super expensive to buy, and I’m sure you can find a cracked version on the high seas if you want to.
