92 Chapter 2 Setting a Script’s Global Parameters

Note: The global controls also appear in the Parameters1 tab when Shake is first

started, or whenever you create a new script.

The global parameters that can be seen in the Globals tab of the Shake interface are

divided into several groups.

The Main Global Parameters

These parameters control the duration and format of the output from your script. While

these parameters can be changed at any time, it’s a good idea to set them to the

proper values before you begin any serious compositing.

timeRange

This parameter defines the number of frames in your project. This parameter can be

changed at any time. The timeRange is generally represented by a starting value and

an ending value, separated by a dash. For example, a 10-second clip in a project that’s

set to a frame rate of 24 fps would have a timeRange parameter set to “1-240.”

The fastest way to set the timeRange is to open the Globals tab and click Auto, which is

located to the right of the timeRange field.

Clicking Auto automatically populates the timeRange parameter by calculating the

duration from the earliest frame in any FileIn node to the last frame in any FileIn node.
