Reverse LUT DaVinci Resolve: Inversion Setup & CST Guide

Master the reverse LUT DaVinci Resolve workflow using our professional guide. Learn how to remove LUT from footage, undo LUT grade bakes, and configure a color space reverse transform (reverse CST) in node graphs to unbake color grade metadata without channel clipping.

Setting Up Invert Nodes in DaVinci Resolve

When colorists try to manually reverse a LUT in DaVinci Resolve, they often apply an inverse 3D LUT directly onto a node. However, if the node input is not set up correctly, this math can clash with Resolve's timeline settings. To perform a clean Resolve Invert LUT operation, you must isolate the transform. Place a Color Space Transform (CST) node before the LUT, matching the camera's input curve (e.g. Sony S-Log3) to Rec.709. Then apply the reverse LUT node. This ensures the look-up table receives linear or log-referred data coordinates rather than compressed monitor feeds, avoiding severe hue shifts.

Dealing with Clipping and Gamut Mapping Out-of-Bounds

A common issue in LUT inversion is highlight clipping. Because sRGB caps values at 1.0 (white), any colors that exceeded this range during shoot are clipped. Reversing the LUT will pull the values down, but will leave a flat plateau. To resolve this, use Resolve's gamut mapping and highlight recovery settings on the raw node. By extending the dynamic range before passing it to the Reverse LUT, you allow the math to calculate smooth gradients rather than generating sharp, pixelated borders.

Best Practices for Resolve Color Management (RCM) Inversion

For professional workflows, utilizing DaVinci Resolve Color Management (RCM) or ACES is highly recommended. RCM automatically maps input feeds (such as S-Log3) to the timeline working space (like DaVinci Wide Gamut/Intermediate). When importing Rec.709 elements, instead of manually applying nodes, right-click the clip and specify the Input Color Space. RCM will automatically apply the inverse mapping, translating the clip into your timeline space without introducing color channel clipping.
