iMovie should just "fill" the screen with the photo.  You could scan  
a few of your various sized photos, bring them into iMovie to verify  
what iMovie will do.   iMovie really doesn't care about dpi, it just  
has a final resolution of 72 dpi no matter what the resolution is of  
the photo.

I agree with Nick, scan at hight resolution possible on the scanner.
