Improved Smoothness for Speed Modifiers in V12

[Igor]

Hi,

In PTE AV Studio 12, we fully rewrote the interpolation algorithm between keyframes - it has greatly improved the smoothness of speed modifiers over long time intervals.

For example, if you use a speed modifier ("Smooth") to create a long panorama (20 seconds) with a fast pace of movement, V12 demonstrates a smoother beginning and ending for the animation than V11. 
At slow panning speeds, there is no noticeable difference between V11 and V12.
