Using LUTs in other apps

Luttie doesn't install a plugin into your editing app. You export a LUT, a standard .cube file, and load it the way that app loads any LUT.

A native Luttie plugin, for DaVinci Resolve first and then Premiere Pro, is in development. It has no release date yet; the film emulation plugin page has a waitlist. Until it ships, the steps below are how a Luttie look gets into your editor.

Keeping your LUTs in one folder

Instead of downloading LUTs one at a time, Luttie can keep a folder of them up to date. On your Account page, under LUT folder, choose a folder and Luttie makes a Luttie LUTs folder inside it. Each sync adds what's new:

• the free LUT library, for every account
• the packs you own, and every pack on Lifetime
• on Pro, the looks you save in the editor Pro

Everything sits in one Luttie folder inside it, with Free, Packs and My looks in that. In the editor, File → Sync LUT folder syncs from there, and a look you save goes straight into the folder.

It works in Chrome and Edge. Other browsers can download the same files as a zip. Browsers don't allow Documents or Desktop themselves to be chosen, only a folder inside them.

DaVinci Resolve

1. In Resolve, open Project Settings → Color Management → Open LUT Folder, copy the .cube in, then click Update Lists.
2. On the Color page, right-click a node and choose LUTs, then your file.

With the Luttie LUT folder, skip step 1: open Preferences → General, click Add under LUT Locations, choose your Luttie LUTs folder and save. Your LUTs then appear in one Luttie folder in Resolve's LUT browser, and new ones arrive with each sync. This works in the free version and Studio.

Putting the LUT on its own node lets you adjust its strength with the node's key output. Full Resolve guide.

Premiere Pro

In Lumetri Color → Creative → Look, choose Browse and select the .cube. The Intensity slider under it sets the strength. Full Premiere guide.

Final Cut Pro

Add the Custom LUT effect to a clip, then in the Inspector set LUT to Choose Custom LUT File…. Its Mix slider sets the strength. Full Final Cut guide.

CapCut

• CapCut desktop: Adjustments → LUT → Import, then apply it to the clip. Full CapCut guide.
• CapCut on a phone can't import custom LUTs. Grade in Luttie and bring the exported image or video in instead.

Filmora

Select the clip, open Color → Basic and turn on LUT. Choose Load new LUT… (on a Mac, Import LUT…) and select the .cube. The Strength slider sets how much it applies, and Protect Skin Tones keeps faces from shifting. Filmora LUTs.

Photoshop

Add a Color Lookup adjustment layer (Layer → New Adjustment Layer → Color Lookup) and load the .cube in its 3DLUT File menu. Lower the layer's opacity to reduce the strength. Full Photoshop guide.

After Effects

Add an adjustment layer, apply Apply Color LUT and choose the file. Full After Effects guide.

Lightroom

Lightroom can't load a .cube directly. Adobe Camera Raw can build one into a profile, which Lightroom then lists alongside your other profiles. Steps for Lightroom.

Capture One

Capture One can't load a .cube. In the export dialog, choose Capture One as the format (beta), or turn an existing .cube into one with the LUT converter. You get a zip with a style (.costyle) and the ICC profile it applies:

1. Unzip both files into Capture One's Styles folder (on Windows, Styles50 inside %LOCALAPPDATA%\CaptureOne) and restart Capture One.
2. Apply the style from the Styles tool. It sets the profile under Base Characteristics → ICC Profile.
3. Set Base Characteristics → Curve to Linear Response, so Capture One's own contrast curve doesn't stack on the look.

The profile assumes standard Rec.709 colours, so on raw files the result is close to the editor's rather than exact. It applies to the base layer only.

Affinity Photo

Add a LUT adjustment layer (Layer → New Adjustment Layer → LUT), click Load LUT… and select the .cube. Lower the layer's opacity to reduce the strength. Affinity Photo LUTs.

darktable

Set a 3D LUT root folder in preferences → processing first: the module's file picker stays inactive until you do. Put the .cube in that folder, turn on the lut 3D module in the darkroom, choose the file and set the application colour space to Rec. 709. darktable LUTs.

RawTherapee

RawTherapee's Film Simulation tool reads HaldCLUT images, not .cube files. Turn the .cube into a HaldCLUT .png with the LUT converter, put it in the folder set under Preferences → Image Processing → HaldCLUT directory, and restart RawTherapee. Then on the Color tab, turn on Film Simulation and pick it; Strength sets how much it applies. RawTherapee LUTs.

Lumix cameras

Panasonic Lumix cameras can load a LUT to show it on the screen while you shoot, and newer bodies can record with it. In the export dialog, tick Panasonic VLUT to get a .vlt, Panasonic's own format. Recent bodies also read a .cube of up to 33 points.

1. Grade a V-Log photo or a frame from V-Log footage, with Film → Source or the Camera panel set to Panasonic V-Log. The camera applies the LUT to V-Log, so a LUT built on a normal photo looks wrong there; the export dialog warns you.
2. Copy the file to the top level of the SD card, not into a folder. On cards formatted FAT32 (32 GB and smaller) keep the name to 8 characters.
3. Load it from the card in the camera's LUT menu: LUT Library on newer bodies such as the S5 II, or V-Log View Assist → LUT File Read on the GH5 II and S1H. The exact path varies by model, so check your camera's manual.

If the LUT looks wrong

• Far too contrasty or saturated: the LUT was probably built for normal (Rec.709) images and is being applied to log footage, or the other way round. Match the LUT to the footage. See Log footage.
• Too strong: lower the app's intensity or opacity control, or export with Also at 50% and 75% strength.
• Missing vignette or grain: LUTs can't carry those. See what goes into the LUT.
