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.
