About the key frame duration
The KfDur value (key frame duration) for key frame n corresponds to the
interval between key frame n and key frame n+1. Therefore, if the settings
are as follows:
Key frame 1 ... not effective
Key frame 2 ... KfDur 100
Key frame 3 ... KfDur 50
Key frame 4 ... KfDur 50
The interval between key frames 1 and 2 is twice that between the other
pairs of frames. For example, if the transition duration is set to 100 frames,
the transition will proceed as follows:
Key frame 4 t 3 ... 25 frames
Key frame 3 t 2 ... 25 frames
Key frame 2 t 1 ... 50 frames
Setting the type of interpolation
When executing the effect, using the F1 button in the menu, you can set
the type of interpolation between key frames as follows:
Lin: linear interpolation
S-Lin: S-curve interpolation
Spln: spline interpolation
V-Spln: parameterized spline interpolation
If you select V-Spln, with the F2(Tens) knob you can adjust the tension of
the spline curve in the range –100 to +100. This controls the smoothness,
with the initial value 0 and –100 giving the smoothest result.
