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

”iMovie 10.1.7 won’t import AVCHD files taken with my Sony 5K any longer after upgraded to macOS High Sierra. After starting iMovie and Importing Media from SD card reader on iMac – ‘Select All’ – iMovie stalls. The progress bar shows ‘Importing from…reference number .mov’ but stops on clip 1. However the clips are displayed and can be run temporarily. The .mts clips then go black with ? mark and ‘No Camera’. Up to a month ago I had no such problems for over 5 years with the same Sony 5K camera and running Sierra on my ageing mid 2007 iMac. Is the upgradation to High Sierra is the cause of the problem? Please kindly advise a solution if you know. Thanks in advance.”
