Importing the 8GB of high-res* footage taken with my defunct Sanyo Xacti VPC-HD1000 on its first and only six cave dives took over 90'... but now I've got about 90' of MPEG4 source material neatly stored in my iPhoto library and ready to be edited into a wanna B movie with iMovie 08 on my iMac. That is, screening is in progress!
Since mixing high and low resolution footage within one movie is a really bad idea, I'll import the 14GB of low-res* footage taken with my Sea&Sea DX8000G later on, as soon as I've got an external HDD.
