LuttieLUT Export — Create .cube and .3dl Files in Your Browser
A LUT (Look-Up Table) is how a color grade travels from your creative tool to your NLE. Luttie lets you build a grade with RGB curves, color wheels, and HSL secondaries — then exports it as a .cube or .3dl file that works in DaVinci Resolve, Premiere Pro, Final Cut Pro, and CapCut. No plugins, no software, no install.
Every format your workflow needs.
Luttie exports standard LUT formats that load into every major video editing application — without any conversion steps.

Frequently asked questions
What is a .cube LUT file?
A .cube file is a 3D Look-Up Table — a small data file that maps every input color to a new output color. It encodes a complete color grade in a compact, software-agnostic format that every major NLE understands. You create your grade visually in Luttie, and the .cube export captures that transformation mathematically so you can apply it in one click to any footage.
Does Luttie support DaVinci Resolve LUTs?
Yes. Luttie exports standard .cube files at 17pt or 33pt that DaVinci Resolve reads natively. In Resolve, go to Color > LUTs > Apply LUT, or drag the file directly onto a node. The same file works in Premiere Pro (via Lumetri Color), Final Cut Pro (as a custom LUT), and CapCut.
What's the difference between a 17pt and 33pt LUT?
The number refers to the grid size of the 3D LUT cube. A 17pt LUT has 17×17×17 = 4,913 data points, which is smaller and faster to load. A 33pt LUT has 33×33×33 = 35,937 points, giving much more precise color reproduction — especially in subtle transitions. For delivery and professional work, 33pt is recommended. For quick previewing, 17pt is fine.
Can I export a LUT pack?
Yes — with a Pro account, you can export a LUT pack that includes three .cube files at 50%, 75%, and 100% intensity, bundled in a single .zip file. This makes it easy to offer flexibility when sharing a color grade, so editors can dial in exactly how strong the look should be on their footage.
