Using the ACES CDL Grading Mode

Silverstack XT has the capability of reproducing ACES workflows.

Different versions of the ACES workflow are available from the Preferences panel:

  • v 1.0.3 (ACEScc and ACEScct)
  • v 1.0.2
  • v 1.0.1
  • v 1.0.0
  • v 0.7.1
  • v 0.7.0
  • v 0.2.0

These ACES versions have different IDTs (Input Device Transforms) and ODTs (Output Device Transforms). Please, make sure that the ACES version used in Silverstack XT matches the one used during the post production process for maximum color accuracy.

The grading nodes displayed in the ACES mode are divided in two parts:

  • ACES color transformation panel
  • CDL controls

Additionally, Silverstack XT offers the ACES CDL Advanced grading mode. This grading mode lets you add multiple grading nodes between the IDT and ODT for advanced workflows.

Managing ACES Versions

In the Silverstack preferences you can manage the available ACES versions and transforms:

The dropdown lets you select the ACES version for new looks. Every new look will be initialized with the ACES version selected in the dropdown in the preferences.

That means that every look in the library made with an ACES grading mode has an associated ACES version (you can find that version in the “ACES Mode” column in the Silverstack library). Saving looks with different ACES versions to the library will make it easy to compare the look of different ACES versions effortlessly.

In the section “Available ACES Transforms” you can find the available ACES versions and its associated transforms. The icon in the status bar will either signalize an available set of transforms (green checkmark) or a set of transforms that can be downloaded from the servers (download icon with downwards arrow).

Click the button “Check for New Versions” at the bottom of the preferences window to see if new ACES versions are available to download from the Pomfort servers.

Supported ACES IDT and ODT formats

Before starting to create your grades, select the correct IDT (matching your camera system) and the ODT (matching the output display color space) from the color transformation panel. LiveGrade Pro currently offers the following set of IDTs and ODTs:

The CDL controls behave the same way as in the CDL Grade mode and can also be exported as usual from a saved grade. ACES grades can also be exported as 3D LUTs, including the CDL values, IDT and ODT.
