Apple Color 1.0 - Manual (Page 106)

106 Chapter 5 Setup
 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.
 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.
 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.
 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

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

R
image data for display:
 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.
 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.
 To generate a set of proxy media for your project, choose File > Proxies > Generate
Proxies.
 To delete all of the proxies that have been generated for a project, choose File >
Proxies > Delete Proxies.
