3D LUT & Color Management

OmniScope supports applying colour transforms to input sources using 3D LUTs, 1D LUTs, ICC profiles, and OpenColorIO (OCIO) configurations. This lets you preview graded images, match monitor profiles, or convert between colour spaces — all without affecting the original signal.

Input 3D LUT

Each input source can have its own 3D LUT applied before the signal reaches the scopes. This is useful for monitoring how the image will look after a grade, or for converting log/RAW signals to a display colour space.

Applying a LUT

1. Open the 3D LUT browser — Options > 3D LUT or use the keyboard shortcut ⌥D (macOS) / Alt+D (Windows) to toggle LUTs on all inputs

2. Select a LUT file from the browser

3. Enable Input LUT in the input settings

The LUT is applied per input slot, so each connected source can use a different transform.

Supported Formats

Format	Extension
3D LUT	.cube, .3dl, .csp, .lut
1D LUT	.cube, .spi1d (1.10.139+)

LUT Options

Option	Description
Tetrahedral interpolation	Higher-quality LUT interpolation (more accurate but slightly slower)
Apply to output	Include the input LUT in NDI/SDI output signal
Apply to snapshot	Apply the LUT when comparing snapshots in split mode

ICC Profiles

ICC profiles can be loaded to compensate for monitor colour characteristics. OmniScope can also read the system's display ICC profile on macOS.

Setting	Description
Display ICC profile	Use the monitor's ICC profile for accurate colour display (macOS)
Custom ICC profile	Load a specific ICC profile file

OpenColorIO (OCIO)

OCIO support requires a Pro license.

OmniScope integrates with OpenColorIO v2 for professional colour pipeline management. Load a custom OCIO configuration to access all colour spaces defined in your pipeline.

• Set the OCIO config path in Preferences

• Select input and display colour spaces from the OCIO configuration

• Colour space primaries from the active OCIO config are shown in the CIE Plot

3D LUT / ICC Scope

The dedicated 3D LUT / ICC scope shows the effect of the colour transform in a separate viewer, letting you compare the original and transformed image.

Keyboard Shortcuts

macOS	Windows	Action
⌥D	Alt+D	Toggle input 3D LUT on all sources
