If for any reason you need to convert Sony MHS-FS2 AVCHD mts files for instant editing in Final Cut Pro X, you may have interest in this guide. It explains how to transcode Sony MHS-FS2 AVCHD media to FCP X preferred Apple ProRes codec for a fast and smooth workflow.

How to transcode AVCHD mts files to ProRes for FCP X editing

“Hey folks, I’ve had trouble with Sony MHS-FS2 mts files in FCP X. FCP X hung several times trying to import all that media at once (leaving in location, not copying to the stupid library secret archive). I’ve broken it down into chunks to import, and some folders are fine, but the MTS clips don’t look promising (loooong progress bars of Processing Files for Import that don’t seem to progress). It seems to me that FCP X just can’t handle any volume of MTS files. Can anyone think of any alternative workflows, or anything I’m missing before I toss it in trash? Actually, this is my first FCP X project. I would really appreciate any help.”

You are probably trying to edit .MTS files extracted from the AVCHD wrapper. The performance issues you describe are a known issue. MTS files should never be removed from the AVCHD wrapper, and if you do, FCP X does not handle it well. The easiest and best solution is re-encode the Sony MHS-FS2 MTS files to ProRes codec before import using Video Converter for Mac.
