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.
If you use Brainstorm on a single one-dimensional property (such as Opacity, but not Position), the Randomness value that controls the amount of
variation (mutation) is replaced by a Spread value. The variants that are presented in the Brainstorm dialog box are then not random, but
represent a range of values around the central value. The original composition appears in the center tile of the dialog box, and you can only select
one variant on which to base the next Brainstorm operation.
Though you can’t directly use Brainstorm on expressions, you can use Brainstorm on the properties of Expression Control effects, to which
expressions can refer.
1. Set a work area and region of interest for the duration and spatial area of the composition that you want to preview during the Brainstorm
session. (See Work area and Region of interest (ROI).)
