Panasonic camera recorded in?
If it was some proprietary format, that's a problem but there are many camera's out there that record in QuickTime format.
What did you try, in regards to getting the files read?
I have a 2006 mac OS X 24 inch totally updated with Snow leapard and all updates and Ilifes, I can not find a still camera that also has HD movie ability that will work in Imovie. Any suggestions. I had to return a beautiful Panisonic that even recorded in sterio because it would not read the files.
