What is a LUT and where do I get .cube files?

A LUT (look-up table) maps every input color to an output color; it is the standard way colorists save and reuse a grade. .cube is the most widely supported format: you can export one from DaVinci Resolve, Premiere or Final Cut, download free or paid LUT packs, and camera makers publish official LUTs that convert their Log footage to normal color.

My footage is Log — can I use the built-in looks directly?

The built-in looks are designed for normal Rec.709 video, so on flat Log footage they will look washed out. Load your camera maker’s Log-to-Rec.709 LUT first and export, then apply a look to that result — or use a creative LUT made specifically for your Log format.

Will the preview match the exported video?

The preview applies the LUT to the extracted frame pixel by pixel with trilinear interpolation, and the export uses FFmpeg’s lut3d filter — the same math, so only tiny rounding differences remain. Intensity is pre-mixed into the LUT; because a LUT is a point-wise mapping, that gives the same result as blending pixel by pixel.

Is my video uploaded? Is it free?

Nothing is uploaded — preview and export both run in your browser (the export uses FFmpeg WebAssembly), and everything is discarded when you close the page. The tool is free, with no sign-up and no watermark.

🌇Apply LUT to Video Online - .cube LUTs & Cinematic Looks

Apply a LUT and give your video a consistent, cinematic grade in one step. Load your own .cube file — 3D LUTs, 1D LUTs and DaVinci Resolve LUTs with a 1D shaper are all supported, and LUTs with a non-0–1 domain or an oversized grid are resampled automatically — or use one of seven built-in looks: teal & orange, warm film, cool blue, bleach bypass, high-contrast black & white, vintage fade and moody, each generated in code as a 33³ 3D LUT. An intensity slider blends the effect from 0 to 100%. Once you upload, a frame is extracted and graded pixel by pixel in your browser for a live preview; drag the divider across the image to compare the original and the graded result, and pick any point in the video to preview. When you are happy, FFmpeg’s lut3d filter processes the whole video with tetrahedral (default, most accurate), trilinear or nearest interpolation, and outputs an H.264 MP4 with the original audio kept. You can also download the current LUT, intensity included, as a .cube file for CapCut, Premiere, DaVinci Resolve and other editors.
