106 Chapter 5 Setup

Â Grading Proxy: 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.

Â Playback Proxy: Lets you choose a proxy resolution to use during playback,

increasing your playback framerate by lowering the quality of the image. When

playback stops, the image goes back to its full resolution.

Playback, Processing, and Output Settings

The following settings affect playback quality and speed.

Â Video Output: The options in this pop-up menu correspond to the video output

options available to the broadcast video interface that’s installed on your computer.

Choose Disabled to turn off video output altogether.

Note: Currently, Digital Cinema Desktop previews and Apple FireWire output are not

available for monitoring the output from Color.

Â Force RGB: This option is disabled for standard definition projects. This setting is

meant to be used when you’re working with high definition Y´C

source media

that you’re monitoring on an external broadcast monitor via a supported broadcast

video interface. It determines how the RGB image data that’s calculated internally by

Color is converted to Y´C

image data for display:

Â If Force RGB is turned off, this conversion is done by Color in software. This

consumes processor resources, and may noticeably reduce your real-time

performance as a result.

Â If Force RGB is turned on, Color sends RGB image data straight to the broadcast

video interface that’s installed on your computer, and relies on the interface to do

the conversion using dedicated hardware. This lightens the processing load on

your computer, and is recommended to optimize your real-time performance.

When monitoring legalized video between 0 and 100 IRE, there should be a minimal

difference between the image that’s displayed with Force RGB turned on or off.

Generating and Deleting Proxies

In order to use proxies while working on your project, you need to first generate a set

of half- and quarter-resolution proxy media for your project.

Â To generate a set of proxy media for your project, choose File > Proxies > Generate

Proxies.

Â To delete all of the proxies that have been generated for a project, choose File >

Proxies > Delete Proxies.
