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

“I’ve worked with Sony ILCE-9 MTS files in many projects currently in iMovie. Now suddenly all those files in all those projects I’ve worked on have no audio. Like iMovie suddenly does not recognize the audio on them and they’re all completely silent with no audio. All these files had audio before, and all I can think of that changed is I did a few updates on my Mac and in the app store. Is there a fix for the issue?”

Current iMovie 10.1.8 and High Sierra does not convert the MTS files like it used to do in the past. Try converting the Sony ILCE-9 MTS files to AIC .mov using the Video Converter for Mac.
