Opening AVCHD MTS files on Mac OS

In macOS Sierra, when I try to access the .MTS video files from my Sony handy cam, the folder AVCHD always opens up the QuickTime preview window from where we can export the video to .mov file. In case, If I want to copy the .MTS file from the handy-cam’s hard disk directly, there is no straightforward option to do so. After playing around for some time, I have figured out a technique to copy the .MTS video files directly from the handy-cam’s hard disk. Here are the steps I have followed.

Steps for opening AVCHD MTS files on Mac

  1. Connect the handy-cam to the mac using USB.
  2. In the finder, you will notice three folders DCIM, PRVATE and AVCHD. AVCHD is the one which has the movie files. It appears as an application. On double-clicking, it will open the QuickTime preview window. So DO NOT double-click.

  5. You may see another folder BDMP, select it and right-click to open the pop-up menu. In the pop-up menu again select Show Package Content.

  2. Unfortunately this doesn’t work for me… the ‘stream’ folder doesn’t seem to contain anything at all… Which is strange, because when I watch the footage on the actual camera I can see everything fine…
