I’m on a Mac Mavericks 10.9 using iMovie ’11, but it doesn’t recognize the .MTS movie files from my camera. What’s up with that? VLC player will play them but then I’m not able to edit the MTS in iMovie on Mavericks. Fortunately, I’ve worked out the best solution to importing MTS to iMovie program under Mavericks. Share with you now.

Convert MTS to AIC MOV MOV for iMovie

Part I. Import MTS to iMovie from Camcorder

MTS files are part of the AVCHD video format used by a number of digital camcorders. The iMovie video editing application that comes with Apple’s iLife suite lets users import MTS files into the application directly from a camcorder. Steps:

>1. Connect the digital camcorder to the computer through the USB connection cable that came with the device. Double-click the “iMovie” application icon to launch it.
>2. Click the “File” menu and select the “Import from Camera” option.
>3. Click the “Camera” option and select “AVCHD” from the menu that appears.
>4. Slide the “Automatic/Manual” slider to the “Manual” position and place a checkmark next to the videos that you want to import.
>5. Click the “Import Checked” button to import the movies into the iMovie application.

While, the point here is if you only have the single MTS video clips out of your AVCHD camcorder stored on hard drive for editing in iMovie, some problems would occur. As far as I know, currently there is no way to import single .mts files to iMovie that you have previously transferred from the camera to your computer unless you have used the Archive method which saves the whole file structure of the camera onto your computer.

And for 60p or 50p MTS footage, even the latest iMovie 11 can not import directly. That’s why you can always meet questions like “how do I get 60p (50p) AVCHD (MTS) in iMovie“…
