I use a Sony SR5E hdd camera. Direct import from the camera into iMovie not a problem, however movies taken from the camera are converted to mts format and are not usable in iMovie. I have tested arround 10 conversion programs to do this, keeping HD quality output, and Turbo.264 was the only one being able to do this fast, clean, easy. If you need something to be converted from one format to the other, without visible loss of quality, this is it!
