I looked it up and it says that it can make 24pfs look like 60fps or higher in slow motion, so you don't get that choppy looking 24fps slow motion. This site:
says that Twixtor can speed up objects too, but does it look good?
Can I speed up a car shot at 24fps, and it will look smooth, as if the car was actually going fast, and not choppy Three Stooges style fast motion? The video made it look smooth, but is there a limit?
