I’m not sure if i got your question right but here is my way:
Just go to link below, download the right plugin for your version of FCP and then just drag and drop the card number folder to the log & transfer window.
If you got any error you should do 1 more step, make a new folder inside the card number folder and name it “VIDEO” all capital letter then put the HVR folder inside the “VIDEO” folder then drag the card number folder to log and transfer window.

or like other said just use mpeg streamclip or clipwarp. longer transfer time. (in my experience)
