You will need to use Sony’s Clip Browser to import the files, then Final Cut’s XDCAM Transfer to get them into a usable format. Then you can just drag them into FCS browser window and work with them. I have just used the XDCAM Transfer program to download the cards directly to the file I wanted but everyone says this is a bad idea as it does not do error correction which the Clip Browser program does. It is an easy process and, as I have an EX-3 I highly recommend the -1 or -3. Good luck.
