Panasonic TM700 records 1080i and 1080P 50/60 fps.

FCP X can only accept 1080i and it can not import 1080 50/60p files. You must use a convert tool to change 50/60 fps MTS to MOV with pro res.
I use *** to comlete the conversion from MTS to pro res. It works like a charm.
Actually even though 1080i videos, I still to convert them to pro res as I save all my video MTS only off the camcorder to the hard drive of my iMac. FCP X will recognize the BDMV whole structure to import MTS files. I do not like putting all messy folders on my mac. So I prefer to convertion. It is my way.
Good luck.
