Apple Color 1.0 - Manual (Page 322)

322 Chapter 17 Render Queue
On the other hand, you may need to render the entire program after all, such as when
you need to generate another set of media in a different format, or if the project is
short enough that there’s no need to break up the rendering.
Which Effects Does Color Render?
Projects that are imported from XML and EDL project files may have many more effects
than Color is capable of processing. These include transitions, geometric
transformations, superimpositions, speed effects, and still images. When rendering your
finished program, your import/export workflow determines which effects Color renders.
In particular, if you import an EDL to grade and export 2K DPX image sequences to be
printed to film, Color renders the shots in your project very differently than if you’ve
imported an XML file, and are rendering QuickTime files to be sent in a return trip back
to Final Cut Pro.
In all cases, the corrections you’ve made using the Primary In, Secondary, Color FX, and
Primary Out rooms are always rendered.
Rendered Effects for 2K Output
When you’ve imported an EDL and are outputting 2K DPX image sequences, all of the
transformations you've made in the Geometry room’s Pan & Scan tab are rendered.
Effects that you need to create to finish the project that aren’t rendered by Color
include video transitions, speed effects, composites, and titles. These must be created
in another application such as Shake.
Effects Aren’t Rendered When Sending to Final Cut Pro
When you’re shepherding a project through an XML-based Final Cut Pro to Color round
trip, all transitions, filters, still images, generators, speed effects, superimposition
settings, and other non–Color compatible effects from the original Final Cut Pro project
are preserved within your Color project, even if those effects aren’t visible.
The Graphics Card You’re Using Affects the Rendered Output
Color uses the GPU of the graphics card that’s installed in your computer to render
the color correction and geometry adjustments that you’ve applied to the shots in
your program. Different video cards have GPU processors with differing capabilities,
so it’s entirely possible for the same Color project to look slightly different when
rendered on computers with different graphics cards. To ensure color accuracy, it’s
best to render your project on a computer using the same graphics card that was
used when color correcting that program.
