Effects in Avid Liquid: The Basics
For Example...
For example, you have an effect with two Key Frames. The first Key Frame is called KF1; the second, KF2.
To keep things simple, the only difference between KF1 and KF2 is the color of the clips’ borders: With
KF1, the image has a red border, while with KF2 it has a blue border.
The beginning of the effect is represented by KF1 (red border). KF1’s values are positioned at the bottom
left-hand corner of the grid. KF2’s values are in the top right-hand corner (blue border). The horizontal
axis between KF1 and KF2 is the time axis; the vertical axis represents the change in the effect, in this
case, the color of the border.
Linear Acceleration
The diagonal line through the grid shows that there is a steady rate of change over the duration of KF1:
border color changes steadily from red to magenta to purple to blue as you run the effect. This is linear
acceleration, the rate of change is constant from beginning to end.
