AVCHD video is not recognized or cannot be transferred to a Macintosh computer.

Macintosh® computers do not support AVCHD video recorded in 60p (1080 and 720). If you want to easily transfer video to a Mac, we recommend changing the recording format on the camera. Depending on the camera, you can change it to MP4 or AVCHD such as 24i, 60i, etc. Alternatively, you can manually copy videos  recorded in 60p (1080 and 720) to your computer.

Media converter software is available for Mac computers that may allow you to transfer video that was recorded in 60p. This software is available at Sourceforge website.

IMPORTANT:

• AVCHD video is only supported with iMovie® 10.0 software or newer. It is recommended the iMovie software on the computer be updated to the newest version to ensure compatibility.
• The computer requires an Intel® Core Duo processor or better to support AVCHD video.
• If both AVCHD and MPEG2 or MP4 formatted movies are recorded, the AVCHD movies may not be recognized. If this happens, import all the MP4 or MPEG2 movies to the computer and then delete them from the camera. Afterwards, disconnect and reconnect the USB cable so the AVCHD movies can be recognized.
• Power Mac® G5 does not support the AVCHD format.
