>interpolated/in-betweened That's the problem: no matter how smart your algorithm is, you cannot make animation look smooth by only adding frames. Not even human animators could do that. The framerate of animation is irrelevant. What matters is the number of drawings per second, not the number of frames. An intelligent system would interpolate between drawings, which would often require modifying or deleting frames from the source. I'm not some purist claiming that this is an evil technology. It just plain doesn't apply to animation, except for pans or the rare scene animated at a full 24 FPS.
