iMovie won’t import Sony Alpha a7 II AVCHD MTS files

iMovie won't import Sony Alpha a7 II AVCHD MTS files properly? Are there any good workarounds to go through this? In this tutorial, we will show you a workaround to re-encode Sony Alpha a7 II AVCHD footage to Apple InterMerdiate Codec for use in iMovie flawlessly.

"I've worked with Sony Alpha a7 II 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 Alpha a7 II MTS files to AIC .mov using the Video Converter for Mac.
