Controls Tab
Random Seed
The Random Seed control contains the value used to seed the random number generator.
Given the same seed, a random number generator always produces the same results. Change
the seed if the results from the randomizer are not satisfying.
Smoothness
This control is used to smooth the overall randomness of the Shake. The higher the value, the
smoother the motion appears. A value of zero generates completely random results, with no
smoothing applied.
Lock X/Y
This checkbox is used to unlock the X- and Y-axis, revealing independent slider controls for
each axis.
Minimum and Maximum
This control is used to determine the overall strength of the shake. The low values represent the
lowest value that can be generated by the randomizer, and the high values represent the
highest values. To create a Shake that moves a center crosshair anywhere within the image, set
the Minimum to 0.0 and the Maximum to 1.0. To restrict the motion to a smaller shake in the
bottom-right corner of the image, set the Minimum to 0.70 and the Maximum to 0.90.
Example
1 Create a new comp, and then add and view a Text node.
2 Type some text in the Text node.
3 In the viewer, right-click over the Center control of the text and choose Modify With >
Shake Position.
4 In the Inspector, select the Modifiers tab and set the smoothing to 5.0.
5 Set the Minimum to 0.1 and the Maximum to 0.9.
This adds some chaotic movement to the text. However, we can change this over
Go to frame 0 and in the Inspector click the Keyframe button to the right of both the
Minimum and the Maximum controls.
6 Go to frame 90 and adjust the Minimum to 0.45 and the Maximum to 0.55.
7 View the results.
Now, the text starts out by flying all over the screen and tightens in toward the
center of the screen as the comp plays.
