Bit of a challenge question that. Unlikely anyone will know. But may have an uncle who works for Steve or the bloke who invented iMovie08 who started it all Seriously I could do with knowing .. because if you go to the Apple iMovie09 Support Camcorder Page - and look at the list of compatible camcorders you may be as shocked as I am to find out that there are VERY FEW AVCHD HD camcorders that are compatible .. if indeed any!!! Yeah. Go on . have a look if yo dont believe me, Thomas. Now - I have had excellent results with my current Panasonic SD5. Great camera and iMovie 08 and 09 did the business in style. Nice... go on YouTube... type in thefartgallery and see the Harley Davidson vids I have done to see how wunnerful the new features of IMovie09 are .. where was I .. Ah yes - so I go out and get a HS9 and SD100 Panasonic. Now - seems the HS9 will be fine. It uses the same light sensor as the SD5 ... IE 3 x CCDs. BUT all the new Panasonics are using 3MOS (3 x CMOS Sensors). And use a different shutter system .. this causes probs .. and is described in the Missing Manual as "video jelly". Now .. if you then use the stabilization feature this makes it even worse!!! AND iMovie cant handle the Cinema modes of these 3MOS cameras To make it even further appalling ... Canons are useless here for the same reason AND Sonys .. so unless you want to use a naff unit like a Samsung or a Panny SD camcorder ... using AVCHD then forget it So what DID iMovie use for its demo footage! Come on!!!!!!
