Chapter 13 Special FX
Linear and Nonlinear (Curve)
The transitions between the play directions (forward and reverse) and speeds can be configured in sev-
eral different ways, as illustrated by the next example. The diagram below describes a clip that is played
repeatedly from beginning to end and from end to beginning:
Clip played alternately forward and backward
The lower speed diagram recognizes only two states of constant speed: In this example, these are approx.
+4 and -4. The transitions have been linearized
. This means that the play direction changes directly (the
straight lines are bent) and that the defined speed is adopted immediately. There is no gradual transition.
The change takes place “within” the Key Frame which, for this reason, is displayed extended at the corre-
sponding height.
