01 — PREVIEW

See exactly what a LUT does, before you use it.

Load your stills and footage, browse hundreds of LUTs and judge them on your own shots, with the measurement tools of a grading suite.

One-key before / after

Compare with a split wipe or toggle with a single shortcut. Frame-by-frame video playback with millisecond timecode.

Live scopes

RGB histogram, waveform, vectorscope with skin-tone line, plus a color temperature indicator.

Adjust, don’t settle

LUT intensity, white balance, tint, highlights, shadows and skin tones. Intensity is kept on export.

02 — FIX NEW IN 2.0

A badly calibrated LUT is no longer a lost LUT.

Harsh contrast, breaking colors, orange skin, artifacts in gradients: the toolbox repairs, cleans and converts your LUTs, then exports them as clean .CUBE files.

6 tools · Tools menu

Normalization

Converts any LUT to the standard 33×33×33 .CUBE format, compatible with all your software.

Repair

Reduces artifacts, clipping and color issues. Brings back blown highlights and crushed blacks.

Smoothing

Softens harsh color and contrast transitions. No more banding in skies and gradients.

Color / Contrast isolation

Keep a LUT’s look without its contrast, or its curve without its color cast. Extracts just one of the two transforms.

Skin tone protection

Limits the LUT’s effect on skin. The look applies to the scene, faces stay natural.

Batch LUT converter

Converts a whole library to another format, or to a cleaned-up version, in a single pass.

03 — ORGANIZE & EXPORT

Your whole library, finally readable.

Thousands of LUTs spread across folders? Each one shows its color strip, metadata and size. Find the right one in seconds.
