look into [line] help you can choose a lower time grain than the default one . it will make things smoother
with simple math you can interpolate between 2 position. interpolate_position = (X*position_2 + (1-X)*position_1) where X vary from 0 to 1.
thanks Cyrille , it wil be useful to me too ... math lessons are way back for me ...
