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. Time Range 1-100 1-100x2 1-100x20 1-20, 30-40 1-10x2, 15, 18, 20-25 100-1 Number of Frames 100 50 5 31 13 100 Frames Rendered 1, 2, 3... 100 1, 3, 5... 99 1, 21, 41... 81 1, 2, 3... 20, and 30, 31, 32... 40 1, 3, 5... 9, 15, 18, 20, 21, 22 ... 25 100, 99, 98... 2 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 highresolution 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, "Using Proxies," on page 137. Chapter 2 Setting a Script's Global Parameters 93
