Accessing Secondary Grading Menus
Chapter 15, Secondary Colour Grading

In Lustre, you can perform secondary colour grading on shots. With secondary colour grading, you isolate and then colour grade colour ranges and objects in your shots. Secondaries are defined by a combination of keys and geometries--keys to isolate colours and geometries to isolate objects or areas in the image. To colour grade an object that moves through time, you can animate the associated geometry using trackers.

Note: Trackers are used for precise secondary animation. However, when a tracker is not required, Keyframes are predominantly used to animate secondaries.

Secondary colour grading is done in the middle of the colour grading process--after the first modifications you make to RGB and Hue curves and before applying Sparks. In Log mode, you can modify brightness, contrast, and hue. In Linear mode, you can modify lift, gain, hue, and saturation.

Note: If you create effects for your image using Sparks, they are processed after secondary colour grading. See Chapter 16, Creating Lustre Sparks Effects.

You can create and colour grade up to 12 unique secondary layers for each shot. Secondaries are processed in numerical order. However, you can toggle secondaries on and off and view the results in the Player. You can also save key presets, secondary presets, and geometry presets. You can also import garbage mask setups, tracker data, and stabilizer data from other Autodesk products.

Hint: GPU acceleration makes faster playback available for certain secondary grading features. See GPU Acceleration.

Warning: The Histogram, Waveform, and Vectorscope functions do not update when GPU acceleration is enabled.
