What makes it difficult to mix frame rates and resolution? I would naively assume that you could just record each scene with whatever framerate and resolution you wanted, combine the whole thing into a single movie with the max resolution and framerate you used out of the bunch, and be done. For example, if you put 24fps material into a 48fps video, it still displays at 24fps.
Edit: since it's an ongoing theme in this discussion, I should point out that my "just record each scene" description is from a technical perspective only. Making it result in a nice-looking work of art is, of course, another matter entirely.
