Chapter 2 Setting a Script’s Global Parameters 93

The starting frame does not always have to be set to 1. For example, to quickly trim off

the first 20 frames of your project, change the timeRange to “21-240.” Doing this

restricts the frame range displayed in the Time Bar and the processing and rendering of

your script to only the frames you need.

Here are some more examples of frame ranges you can define in Shake.

Several parameters and controls in Shake either inherit the timeRange parameter

directly, or allow you to assign its value:

• The Home button in the playback controls

• The Render Parameters window

• The Time Range parameter in the Mixdown Options of the Audio Panel

• The Flipbook Render Parameters window

useProxy

A proxy is a lower-resolution image that can be temporarily substituted for the high-

resolution plates in your script, allowing you to work and see rendered tests faster.

Because the images are smaller, you drastically decrease the processing time, memory

requirements, and the amount of time spent on reading and writing files as you work.

Naturally, the trade-off is that the quality of the image displayed in the Viewer suffers as

well, which is why proxies are generally used only when creating low-resolution comps

or creating test previews. After assembling a script using proxies, you can return your

script to the original, full resolution in order to render the final output.

These controls are linked to the proxy buttons found at the upper-right corner of the

Shake interface, and allow you to switch among different resolutions to reap the

aforementioned benefits. For more information on using proxies, see Chapter 4, “U
