Load a clip and try LUT-style looks in real time. Compare before and after with a split slider, then save a still or export the grade as a .cube LUT for your editor.
Runs entirely in your browser. Nothing is uploaded to any server.
Flip through presets and sliders on your real footage instead of generic sample images.
The split view shows the original and graded image side by side on the same frame.
Export the grade as a standard .cube LUT that most editors and many cameras accept.
Each pixel passes through exposure, white balance (temperature and tint), shadow lift and highlight gain, gamma and contrast. Because those steps act on each color channel independently, they are precomputed into three fast lookup tables. Saturation and split toning, which depend on pixel brightness, are then applied per pixel.
The .cube export samples exactly the same math on a 33 by 33 by 33 color grid, which is a common LUT size supported by DaVinci Resolve, Premiere Pro, Final Cut Pro, OBS and many others. The preview works on an 8-bit, display-sized copy of the frame, so expect small differences compared with a high-bit-depth grade in a professional editor.
Push shadows toward one hue and highlights toward another, the core of looks like teal and orange.
Precomputed tables keep playback smooth even at 960 pixels wide.
Size 33 3D LUT with domain 0 to 1, ready to import.
No. Frames are drawn to a canvas and graded locally in your browser.
Yes. The .cube file is a standard 33-point 3D LUT that most editors can import as a look or creative LUT.
Grading is done per pixel on the CPU. The preview is capped at 960 pixels wide to keep it smooth; the PNG export uses full resolution.
No. The grade is designed on the video as displayed (Rec.709-style). Apply it after any log-to-Rec.709 conversion.
This tool focuses on previewing and exporting the LUT and stills. Apply the LUT in your editor to render the final video.
