Huge iMovie file size.

I made 3 movies in Quicktime from Keynote presentations, sizes 4, 24 and 48 MB, but when I import them into iMovie, the project file grows up to 7+ GB. Could somebody tell me why this happens, and is there a way to make it smaller or am I doing something wrong. That takes up almost all my free hard drive space, and taht is only 1 of three project I want to create.

iM is a DV-editor, meant to copy (=import lossless) from miniDV camcorders via firewire ..

means, iM works with the same compressor/codec/format as camcorders, dv, that is a 13GB/h...

no, no workaround for this, for sure, after finishing your projects, the many export options of iM allow a stronger compression ...

Hi David

Karsten is 100% on this I just want to speculate around how I would do.

Easiest way:
is to get an external hard disk BUT THIS SHOULD be:
- a FireWire disk - no USB/USB2 - will not behave if one stores video material on it and tries to work with is here
- has to be Mac OS Extended or Mac OS Extended (journaled) - DOS/UNIX/Mac OS Exchange will not work

There should be at least 10Gb free space on internal hard disk (thumb-role
is 10% free space). at less than 5Gb the Mac OS gets problems due to that it
really is UNIX with a Mac interface. = lots of temp-files (invisible) and virtual
memory management.

Worse way:
Tidy up the internal hard disk so that it has about 10 - 25Gb free space by
storing old documents elsewhere - eg DVD disks, ext hard disks etc.
