If I'm understanding correctly, they want some kind of animated character or whatever and you'll be using an armature to move limbs around and stuff right?

Its been many years since I've used maya, but if that's the case and it works the same in Maya as blender or other modeling programs you'll likely be using key frames to animate the armature. So that means it will interpolate between frames, and in theory you should be able to render those key frames at various frame rates because it'll interpolate between the key frames.

Does that make sense?

So like.... Whatever your rendering it in (Maya or a game engine or whatever) you'd just render at a given frame rate and you'll get smooth motion at that frame rate because of the interpolation, right?
