Many people have complained about the Smoothness setting for keyframes, mostly because they would prefer it to default to zero instead of one.
I have a new complaint: Smoothness is NOT spatial, but is temporal as well. This is NOT what the help file describes, to whit:
"Smoothness adjusts spatial interpolation: how motion occurs within the frame. A Smoothness setting of 0 produces linear motion from one keyframe to the next. Increasing the setting produces a curved path."
The help file continues:
"If you want to adjust temporal interpolation how motion occurs over time change a keyframe type by right-clicking a keyframe and choosing a new interpolation curve type (hold, linear, fast, slow, or smooth)."
Thus, one control for what happens in space (curved vs. straight), and another for how quickly the keyframes change over time.
Wrong.

Keyframe Veg
Use the Vegas replace function to insert any still photo in place of my media when you open the VEG file.
Both events have eleven keyframes, spaced evenly along the timeline. The movement between each keyframe is exactly the same distance (generated by a script). Thus, you would expect that the movement would be exactly the same as what you would get with just two keyframes, one at the beginning, and one at the end.
WRONG!
Instead, when smoothness is set to one, you get a start/stop feel to the movement as each keyframe is passed. When smoothness for all keyframes is set to zero (which what I did for the second event), the motion is totally smooth.
This sure seems like a bug in implementation. At the very least, the feature is not accurately described in the help file.
