4 .. function:: AssumeFPS(clip clip[, clip src, int fpsnum, int fpsden=1])
7 Returns a clip with the framerate changed. This does not in any way modify the frames, only their metadata.
8 The framerate to assign can either be read from another clip, *src*, or given as a rational number with *fpsnum* and *fpsden*.
10 It is an error to specify both *src* and *fpsnum*.
