I have to use the Lumix DMC-FX75 for a work web project. I stupidly selected the AVCHD option instead of MJPEG thinking 'Ooh fancy HD feature' before realizing it's a nightmare on my imac (just bought maybe 6 months ago) I'm not so well versed in video editing as it is and have tried to upload the video files on a mac & pc with no luck. From reading some threads here I've found that it can be done through imovie 09. How can I upload the video files from the memory card into imovie so I can edit the footage? (where are they? What is their file extension?) I'm a total novice so I would appreciate the help desperately!
