Hey Mike,
I guess I would start off first with the question of how do you WANT it displayed? What can the projector deliver? If the projector can deliver at 1280 x 720 do you want to utilize that? (Is the file going to be blown up to fill the screen anyway?) What kind of creative approach are you taking? Do you want to accentuate the 1960’s 4:3/B&W look and contrast it to the contemporary?
For me it would start at the creative and then go back to your timeline from there. For me, personally I’d rather see something shot at 720p/widescreen stay that way if the projection can exploit it. Your other footage is already dated and the audience knows that. Rezing it up to 720p/widescreen isn’t going to kill it but you could even keep that portion 4:3 (and/or even at DVcam dimensions) so you don’t lose as much rez and keep the entire frame without cropping.
Just my 2 cents, but I guess the first question is what is your creative intent for the piece.
