This iExpressions allows to smooth the keyframed motion of a property.

• Width

  determines the amount of smoothness. The larger the width, the more smooth is the result - a value of 2 means, for example, that the values within a window of 2 seconds are taken into consideration to smooth each value.

• Samples

  determines the accuracy of the smoothing. The more samples the more accurate is the result. For optimal quality it is recommendet to use a value that is 25 or up to 50 times larger than the value of "Width".
