My friend shot videos with the new Panasonic Lumix DMC-ZS3. After downloading the AVCHD Lite .mts videos from DMC-ZS3 to iMovie 8/9/11 and exporting as .mov, the video is 2x speed faster than the audio in normal speed. QuickTime Player does not support the 720p MTS, and the VLC media player does not recognize the DMC-ZS3 .mts files from built-in memory of the camera.
The free to try method is to update VLC to see if it works for the DMC-ZS3 AVCHD Lite 720p MTS videos then. Another solution is to convert AVCHD Lite to MOV with third party software with perfect synchronization. If you have just purchased Lumix DMC-ZS3 digital camera, and have difficulties playing the recorded AVCHD Lite files on iMac, UFUSoft AVCHD Converter for Mac is the recommended Panasonic Lumix AVCHD Lite Mac Converter on OS X 10.4 Tiger, 10.5 Leopard, 10.6 Snow Leopard, 10.7 Lion and 10.8 Mountain Lion.
