Using Proxies
If you're working with a project that uses Cineon or DPX image sequences, you can use
the Color proxy mechanism to work faster with high-resolution media. The proxy
mechanism in Color is not available to projects using QuickTime media, unless you’re
using native RED QuickTime media. RED QuickTime media is capable of generating proxy
data on the fly depending on how the Render Proxy, Grading Proxy, and Playback Proxy
pop-up menus are set.
• Enable Proxy Support: Turning this button on enables the use of lower-resolution
substitute media, called proxies, in place of the source media in your project. Using
proxies increases playback, grading, and rendering performance, although your shots
are displayed at lower quality. If you’re grading DPX or Cineon media, proxies may only
be used once they've been generated; proxies are generated using the same format
as the source media. (For more information on how to generate proxies, see
Generating
and Deleting Proxies .)
If you’re grading native RED QuickTime media, you can turn on proxy resolutions at
any time, without the need to generate proxy media; they’re generated on the fly.
Note: In all cases, while resolution may be reduced, proxies are completely
color-accurate.
• Render Proxy pop-up menu: Lets you choose a proxy resolution with which to render
your output media. This can be useful if you want to quickly render a set of media to
test the return trip of a roundtrip workflow. This menu defaults to Half Resolution and,
in most cases, should be left at that setting.
• Grading Proxy pop-up menu: Lets you choose a proxy resolution to use while adjusting
the controls in any of the rooms. This increases the interactivity of the user interface
and the speed with which the image being worked on updates while you adjust different
grading controls. When you finish making an adjustment, the image goes back to its
full resolution.
• Playback Proxy pop-up menu: Lets you choose a proxy resolution to use during playback,
increasing your playback frame rate by lowering the quality of the image. When playback
stops, the image goes back to its full resolution.
