Actually, as I have come to understand 24 fps is the minimum to look smooth for human eyes. Some consoles even use 60 fps.
But I must admit that I too found it rather odd to find this high framerate in compressed video. If you are wondering the source, it was Ultimate.Spider-Man.S01E01.Great.Power.HDTV.x264-aAF (and E02, E03, E04).
