With Brainstorm, you can rapidly accomplish the following:
•
Compare the results of multiple values for a single property so that you can find the value that works best.
•
Explore the results of randomly modifying any number of properties to achieve a creative result.
Open a template project or apply an animation preset to a layer, select some properties (or entire property groups),
and then use Brainstorm to quickly modify these properties. Starting from such complete material, you can use
Brainstorm to very quickly create your own projects and animations.
You can use Brainstorm on any number of properties and property groups, from one or more layers in the same
composition. For example, you can use Brainstorm to refine the single Stroke Width property for a star on a shape
layer; or you can select the entire Contents property group and use Brainstorm to explore the entire space of properties
for all shapes on the layer.
You can use Brainstorm on any property that has numeric values or options in a pop-up menu in the Timeline panel.
Examples of properties on which you can’t use Brainstorm are Source Text, Mask Path, and the Histogram property
for the Levels effect; however, you can use Brainstorm on the properties of the Levels (Individual Controls) effect.
Brainstorm operates on all selected keyframes. For a property with no keyframes, Brainstorm operates on the global,
constant value.
