I don t understand because it does not make sense.
Lets say we've got 1 fps video - 1 frame each second. With 5/2 frame interpolation the output'll be 2.5 fps:
1st frame - at time 0, 2nd - 0.4 second, 3rd - 0.8 second, 4th - 1.2 sec, 5th - 1.6 sec an so on.
Imagine that red circle is an object moving from left to right.
In the interpolated frame sequence this object will be at positions of the black dot.
