LUT Generator: Turn Your Grade into a .cube File
Build a look with real grading tools on your own clip, then save it as a standard 3D LUT. The file is calculated in your browser, with no upload, account or watermark.

A LUT generator turns a colour grade into a lookup table: for a grid of input colours it records the output colour, and any editor that reads .cube files can then apply the same transformation to other clips. Open a clip above, grade it with Looks, Adjust, Creative or the Pro tools, then choose Export, the LUT (.cube) tab and Export .cube (Shift+L). The studio evaluates your whole grade exactly at every grid point and writes the file in your browser.
Grading on your own footage is the point. A LUT built on a stock photo often looks wrong on a different camera or scene, whereas here you see the result on the shots you will use it on, with scopes to check skin and highlights. If you would rather start from something ready-made, every one of the roughly 300 looks can be exported the same way: see free LUTs. To put a LUT back onto a video in the browser, use apply LUT to video.
How to make a LUT
Open representative footage
Choose Open video or photo (Ctrl/Cmd+O). Pick a clip that contains skin, a neutral grey or white, and both shadows and highlights, so you can judge the look on all of them.
Build the grade
Start with Auto colour or a look, then refine it: Temperature, Contrast and Saturation in Adjust, split toning in Creative, or Wheels and Curves in Pro mode. If the footage is log, set the Footage menu first.
Check it on other shots
Open a second clip, or scrub to a different scene, and use Compare (B) to see the grade against the original. A look that only works on one shot won’t travel well as a LUT.
Export the .cube
Choose Export, then the LUT (.cube) tab. Pick a LUT size of 17, 33 or 65 and choose Export .cube, then Download .cube. The studio lists anything in your grade that a LUT cannot hold.
Test the file
Load the .cube in your editor, or here with Import LUT in Creative, on a clip without any grade. It should match what you saw in the studio.
What a LUT can and can’t store
A 3D LUT is a pure colour mapping: one input colour always gives the same output colour, wherever it is in the frame and whenever it appears. Anything that depends on position, neighbouring pixels or time therefore can’t be stored, and the studio warns you when your grade contains it.
- In the file: the Footage conversion from camera log or HDR, Match colours, the Correction layer (white balance, tone, wheels, curves, HSL), added layers without a mask, the look at its Intensity, and an imported LUT, in the order you placed it.
- Left out: layers limited by a qualifier or window (a LUT can’t tell a sky from a blue shirt), Grain, Vignette, Halation, Bloom, Soft focus, Sharpen and the VHS tape effects, and keyframes, where the start grade is used.
If you rely on a masked layer, keep the masked part in your editor: export the LUT for the overall look, then rebuild the qualifier or window there. Grain and a vignette are easy to add on top in any editor.
Which size: 17, 33 or 65 points?
The size is the number of grid points along each of red, green and blue. Between the points, the editor interpolates, so a bigger grid follows sharp curves and strong hue shifts more closely.
- 17 (4,913 entries, a file of around 140 KB): fine for gentle looks, and the size some monitors, cameras and capture devices expect. Strong curves can show slight banding or hue drift.
- 33 (35,937 entries, about 1 MB): the everyday standard and what most editors and LUT packs use. Our studio grades internally on a 33-point grid, so this matches the preview closely.
- 65 (274,625 entries, about 7 MB): the most precise, for steep contrast curves, colour keys turned into looks or log conversions you want as exact as possible. Larger files load a little more slowly and some devices refuse them.
Our exports use the common .cube layout with a TITLE line, a 0 to 1 domain and red changing fastest, which Resolve, Premiere, Final Cut Pro and most other software read without fuss.
Log input or Rec.709 input?
A LUT expects a particular kind of input. Our exports always produce Rec.709 output, and what they expect as input depends on the Footage setting while you graded.
Rec.709 footage (the usual case)
With Footage on Standard video (Rec.709), the LUT expects ordinary video: phone clips, most camera files, or log footage that has already been converted. Apply it after any conversion in your editor.
Log footage
With Footage set to a camera log profile, the conversion is baked in, so the LUT expects that camera’s log footage directly: in effect a conversion and look in one file. That is convenient on one camera, but you can’t use it on other footage, and you shouldn’t stack it on top of the camera maker’s own conversion LUT. For a pure conversion with no look, export straight after choosing the profile; the S-Log3 to Rec.709 page also has ready-made files.
Using your LUT in other apps
Every editor below reads .cube. The free LUTs page has step-by-step folder locations for the big three; in short:
- DaVinci Resolve: copy the file into the LUT folder (Project Settings > Color Management > Lookup Tables > Open LUT Folder), click Update Lists, then apply it to a node on the Color page.
- Premiere Pro: in Lumetri Color, a creative LUT goes in Creative > Look (Browse) with its own Intensity; conversion LUTs go in Basic Correction > Input LUT.
- Final Cut Pro: add the Custom LUT effect from the Color category of the Effects browser and choose your file in its LUT menu.
- CapCut desktop: Adjustment > LUT > Import, then set the strength slider.
- OBS Studio: add the Apply LUT filter to a source and pick the .cube, which is a quick way to put the same look on a live webcam.
Many camera monitors and recorders can load a LUT for monitoring; check the sizes and formats the manual lists before you rely on one on set.
LUT generator questions
How do I create a LUT from a photo or reference image?
Open the photo you want to grade and build the look on it, or open your video and use Match colours in Pro mode with the reference image, then export the result. Matching is a starting point, so refine it before exporting.
What LUT size should I choose?
33 points suits almost every editor and look. Use 65 for steep curves or log conversions that need the most precision, and 17 when a monitor or device asks for small LUTs.
Why does my LUT look different in my editor?
Usually the input doesn’t match: the clip is still log when the LUT expects Rec.709 (or the reverse), the editor adds its own colour management, or another LUT is stacked on top. Masked layers, grain and vignettes are not in the LUT either.
Is the LUT made on a server?
No. The table is computed from your grade by this page in your browser and saved straight to your device. Your footage is never uploaded.
Can I turn a LUT back into an editable grade?
Not into sliders. You can load any .cube with Import LUT, set its LUT intensity and grade around it, but a LUT is a table of colours, not a list of settings.
