Have you got the JVC GZ-EX250 or GZ-EX210? Have you shot some videos with them? Are you looking for a way to help you ingest EX210 or EX250 1080p clips to FCP for editing?
As far as I know the JVC GZ-EX250 is identical to its linemate the EX210, except for storage: GZ-EX250 features an SD/SDHC/SDXC memory card slot, as well as an internal 16GB flash memory, the EX210 only features an SD/SDHC/SDXC memory card slot. But the recorded videos are same. They all can record 1080p Full HD .mts/.m2ts videos with AVCHD codec and can output 1080/60p video as well.
But if you try imporing the High Definition MTS to FCP, you are likely to get some incompatible troubles, particularly 1080p@60fps movies. AVCHD, including 60fps, is a high compression format, it is a good format for playing on Widnows, but it is not a good editing format on Mac. To put the MTS videos from GZ-EX250 and GZ-EX210 in to FCP without any problem, you need to use the professional MTS to FCP Converter to transode MTS/M2TS movie to a comfortable format for FCP, like ProRes. The tool also can convert AVCHD to any other video format for Mac software with included profiles, so it can keep the HD quality with the best settings.
Below are the simple but useful steps for transcoding 1080p AVCHD videos for FCP.

Step 1: Launch the MTS Converter and load the 1080p 60 MTS files to the program.
Tip: This Mac AVCHD converter also supports several MTS/M2TS files combined into one file with the function "Merge into one".
Step 2: Choose Final Cut pro >> Apple ProRes 422 (*.mov) as output format by clicking the Format bar.
Tip: For FCP 7 or above version, you can choose many output formats,such as Apple ProRes 422 (HQ)(*.mov), Apple ProRes 422(LT) (*.mov), Apple ProRes 422(Proxy) (*.mov) and Apple ProRes 4444 (*.mov)
Step 3: Click the "Settings" icon to make the best settings for editing footages in FCP on Mac. You can set the video frame rate as 30fps(NTSC) or 25fps(PAL), video size as 1920*1080 to keep the best output quality.
Step 4: Click convert button to start converting JVC GZ-EX250/JVC GZ-EX210 AVCHD to FCP.
When the AVCHD to FCP conversion is 100% completed, you can easily transfer the converted file to FCP 6/7 without problems and rendering.
