Using Temporary Proxies Unless you specifically do otherwise, Shake generates temporary proxies (also called on-the-fly proxies) that are created only for frames that are displayed, as needed, and that are discarded once your computer's disk cache is full. Whenever you set the useProxy parameter to something other then Base, Shake scales down the resolution of frames at the position of the playhead as you view them, in order to accelerate your script's performance. Unlike the interactiveScale setting, the image is left at the proxy resolution until you return the useProxy parameter to the Base resolution. Important: The useProxy parameter affects both Flipbooks and FileOut nodes. Temporary proxy images are written first into memory, and then to the disk cache as memory runs out. Shake keeps track of how many times each cached frame has been viewed, and eliminates the least viewed frames first when the cache runs out of room. To change to a lower proxy using the default proxy resolutions, do one of the following: m In the Globals tab, switch useProxy from Base to P1, P2, or P3. m Use the pull-down button menu in the title bar. When activated, the proxy button in the title bar is highlighted with the selected proxy. Chapter 4 Using Proxies 141

Using Proxies

141

Using Temporary Proxies

Unless you specifically do otherwise, Shake generates temporary proxies (also called

on-the-fly proxies) that are created only for frames that are displayed, as needed, and

that are discarded once your computer’s disk cache is full.

Whenever you set the useProxy parameter to something other then Base, Shake scales

down the resolution of frames at the position of the playhead as you view them, in

order to accelerate your script’s performance. Unlike the interactiveScale setting, the

image is left at the proxy resolution until you return the useProxy parameter to the

Base resolution.

Important:

The useProxy parameter affects both Flipbooks and

FileOut

nodes.

Temporary proxy images are written first into memory, and then to the disk cache as

memory runs out. Shake keeps track of how many times each cached frame has been

viewed, and eliminates the least viewed frames first when the cache runs out of room.

To change to a lower proxy using the default proxy resolutions, do one of the

following:

In the Globals tab, switch useProxy from Base to P1, P2, or P3.

Use the pull-down button menu in the title bar.

When activated, the proxy button in the title bar is highlighted with the selected proxy.
