How to apply a LUT in Blender.

Updated November 6, 2026

In Blender, free-standing .cube looks are applied through color lookup tools in the Compositor and, on some builds, strip color controls in the Video Sequence Editor. Labels and availability shift between 2.8x–4.x releases, so use the Look Up Table / strip color path your build actually shows. If Sequencer has no .cube browser, grade a Rec.709 export in Resolve, Premiere, CapCut, or Final Cut, then finish VFX in Blender.

Before you start

• Use a desktop Blender build with Compositor (and Sequencer if you edit there). Confirm your version's color management docs for LUT loading.
• Unzip the download so Blender sees a real .cube file (not a .zip).
• If the footage is log, convert to Rec.709 first, or reserve a technical LUT only for that conversion. See Log vs Rec.709.
• Prefer 33-point cubes for everyday social and YouTube work; keep a 65-point copy if soft gradients matter.
• Decide Sequencer (edit cut) vs Compositor (node grade) before hunting menus that only exist in a tutorial for another app.

Step 1: Open the clip in Sequencer or Compositor

1. Import or strip-add your media into the Video Sequence Editor, or open the shot in the Compositor / render pipeline you use for grading.
2. Confirm color management is set for Rec.709 delivery if that is your target (do not fight a display transform that undoes the creative look).
3. If you only need a quick creative look and Sequencer LUT support is missing, skip ahead to Step 2's Resolve/Premiere path.

Step 2: Load the .cube

1. Compositor path: enable Use Nodes, add the color Look Up Table / LUT node your version documents, and browse to the unzipped .cube.
2. Sequencer path (when available): select the strip, open strip modifiers / color tools, and load the .cube from the control that accepts a LUT file.
3. If neither path accepts a free-standing .cube, export a Rec.709 still or short clip, apply the look in DaVinci Resolve or Premiere Pro, then re-import the graded media.
4. Format notes: What is a .cube file?

Step 3: Rec.709, order, and A/B

• Keep exposure and white balance sensible before the creative LUT; do not stack two heavy creative looks.
• Order of operations that usually stays honest: technical log→Rec.709 (if needed) first, then the creative Filmsilk look, then light secondary polish—not the reverse.
• Mute the LUT node / strip control to A/B a bright exterior, a dark interior, and a face close-up before you export.

Role of each tool: LUT vs color grade.

Step 4: Export a short test

• Export a few seconds at your delivery resolution and check on a second screen if you have one.
• Watch for crushed blacks, neon skin, and titles or graphics that pick up the look too hard.
• Save the .blend so the loaded LUT path stays with the nodes or strip modifiers.

FAQ

Does Blender support .cube LUTs?

Yes, with caveats by workflow. Blender's Compositor can apply color lookup tables, and some Video Sequence Editor builds expose strip color tools that accept LUTs. Exact node and modifier labels move between Blender versions (2.8x through 4.x). If your Sequencer build lacks a direct Load 3D LUT / .cube strip control, grade the Rec.709 export in DaVinci Resolve, Premiere, CapCut, or Final Cut, then bring the graded media back into Blender for 3D / VFX finishing.

Sequencer vs Compositor—which should I use?

For a simple creative Rec.709 look on an edit cut, check whether your Sequencer build has a strip modifier or color tool that browses a .cube. For shot-level grading with nodes, use the Compositor Color / Look Up Table path your version documents. Do not invent a Resolve node graph or Premiere Lumetri panel inside Blender.

Should I apply a creative LUT on log footage?

No. Convert log to Rec.709 first (or use a technical conversion LUT only for that step), then apply a creative Rec.709 look. Filmsilk looks expect Rec.709 input.

Why does nothing change after I load the file?

The file may still be inside a .zip, may not end in .cube, color management may be set so the LUT is bypassed, the node/modifier may be muted, or your Sequencer build may not load free-standing .cube files. Unzip, confirm the extension, check color management, unmute the node, or grade in Resolve/Premiere and re-import.

Where Filmsilk fits

Filmsilk ships standard 3D .cube looks for Rec.709 that load wherever your editor accepts .cube—including Blender when the Compositor or Sequencer exposes a LUT control, plus Resolve, Premiere, CapCut, Final Cut, After Effects, HitFilm, VEGAS Pro, Filmora, Photoshop, and Avid Media Composer after Color Management install. Try every look on your own frame before you buy. The Collection is $29 one-time; Filmsilk Complete is $39 with Studio export.
