I'm using the above mentioned camera for importing HD 1080i video into iMovie. On the Sony it is using the highest possible quality setting, so quite large files. It has a 120Gb hard drive and offers about 900 minutes of record time at that setting. When I import the movies into iMovie however, my mac pro 8 core maxes out and seems to be converting the files. I read on another forum that it does this to convert from Sony's heavily compressed proprietary H.264 files (that the mac can't use) to something more useable. However it says that it will increase the file sizes by around 5X to 10X their original size!! That means 40Gb for one hour of video! Not very cool. Questions: a) Is there any way to have the Mac convert these to a still very high quality but reasonable file size for use in iMovie? b) If not does anyone know if iMovie will eventually include better support for this camera, particularly in terms of importing the original files "as is" or at least close to it, so we don't get this enormous use of hard disk space. I have 1000 Gb drive but that's only 25 hours at that rate, and the drive is already half full with other stuff. c) Do you need a mac pro to play back these files / import them - what about a new Macbook Pro? Can it play back full HD from an external fw800 drive?
