Stills in IMovie

[David Minard]

For "Ken Burns" effects and other use of stills in IMovie (and for that 
matter, Final Cut Express), what resolution should I use in Photoshop? 
I am assuming some of these will have an extreme "zoom in." I also 
assume that I should use an aspect ratio of 4:3, right?

Any other pointers in this regard would be greatly appreciated.
