Sony Creator ToolDiagnostic & Quality Check
3D LUT Validator & Diagnostic Tool
Ensure your 3D .cube LUT will import cleanly into your Sony FX3, FX30, A7C II, A7CR, A1 II, or ZV-E1 camera. Our analyzer verifies syntax, dimensions, mathematical limits, and checks for destructive color banding.
Upload .CUBE LUT to Inspect
What This Validator Checks
- Header syntax: TITLE, DOMAIN_MIN, DOMAIN_MAX, LUT_3D_SIZE
- Dimensions: 33³ or 17³ for Sony camera compatibility
- Data bounds: Clamping of negative (<0) and blown (>1) values
- Gradient continuity: Detects color banding / posterization
- File row count validation vs expected cube grid size
Upload a .cube file on the left to inspect its parameters, integrity, and Sony camera compatibility.
Guide
How to use LUT Validator
Best for: Videographers and filmmakers loading LUTs onto Sony cameras.
- 1Upload or drop any .cube file into the validator.
- 2Inspect the scorecard for dimension check, NaN check, and banding delta.
- 3View the 3D RGB lattice slice preview.
- 4If errors are detected, use the 1-click button to fix and convert it.
Tips
- High banding delta (> 1.2) indicates steep color transitions that may cause visible banding on 8-bit footage.
FAQ
What causes Sony cameras to reject a LUT?
Common causes: 1D format instead of 3D, grid size larger than 33x33x33, missing header lines, or negative numbers.
