OS X Mountain Lion: About AVCHD files and QuickTime Player
Learn about using AVCHD files with QuickTime Player in OS X Mountain Lion.
QuickTime Player in Mountain Lion allows you to play back, inspect, trim, export, and share video from AVCHD media. The AVCHD format is used by high definition consumer devices such as hard disk-based camcorders and digital still cameras with video.
AVCHD media is usually accessed by connecting your camcorder or camera to the Mac via a USB cable. Some devices, such as digital cameras, may also have removable memory cards that can be read using a USB card reader or the SD card slot included with some Macs.
Important: Check the documentation that came with your device (or its online support information) for information about the recommended method of transferring AVCHD media to your Mac.
Once you've transferred your AVCHD media to your Mac, it will appear as a folder on your drive. To access your clips in the media, open the folder and double-click the file named AVCHD, BDMV, or PRIVATE.
If your AVCHD media has a single video clip, then QuickTime Player will simply open the clip in a player window.
Working with Multiple AVCHD Clips
If your AVCHD media has multiple clips, then you'll see them grouped together, like this:
Simply select the clip you are interested in, then click Open to open in a player window.
AVCHD clips are sorted in the clip browser from oldest to newest. You can select both single and multiple clips as well as resizing them in the browser.
