I've noticed that on 10.8 QuickTime takes control over the AVCHD content folder on my cameras memory card, turning it into a package and requiring you to open it up in QuickTime and convert the videos to mov files. Is there any way to disable this? I would much rather have raw access to the .mts files so I can work with them in FCPx.


MacBook Pro 13" Early-2011. 8GB of RAM. 320GB HDD. OS X 10.8.1.

  • Have you tried changing the default application for mts files from an information window?

  • ALl I got is VLC. Quicktime doesn't open MTS files.

  • You could also try editing QuickTime Player's Info.plist. Does the folder end with something that looks like a filename extension? If it does, mdls could give its UTIs.

  • I'll try that. It's a folder on a windows and ubuntu.

  • You can still do a secondary-click (right-click or two-finger-click) on the package and select “show package contents” from the contextual menu to access.
