Summary: First, know that you cannot edit the HD video from this camera(AVCHD format)on a Mac. So the user friendly IMovie software that came with your Mac isn't an option for HD video you shoot with this camera. Apparently you can edit video on a Mac that you shoot in MP4 format, but then why did you buy an HD camera if that's what you wanted to do? No worries, you think. I'll just edit my HD movies using the Windows compatible editing software that comes with the camera.
