How to Use the LUT Blender

The LUT Blender allows you to mix multiple Look-Up Tables (LUTs) at different strengths to create custom color grades. Combine a film emulation LUT with a contrast LUT, adjust blend percentage, and render a new LUT for your editor or camera.

What Is a LUT?

A LUT is a color lookup table, a mathematical transform that remaps input colors to output colors. LUTs are fast and repeatable. Apply the same LUT to 100 shots and they look identical. Popular in digital cinema for consistent color.

Common LUT Types

• Log to Rec.709: Converts flat log footage to broadcast standard. Essential for log shooters.
• Film Emulation: Mimics Kodak, Fujifilm, or other film stock looks. Adds character and warmth.
• Creative Grades: Brand colors (YouTube red, Netflix dark, etc.). One-touch stylization.
• Technical Correction: White balance, contrast, saturation adjustment. Fixes shot-to-shot inconsistency.

Blending LUTs

Blend two LUTs to find a middle ground. For example: 70% film stock LUT + 30% contrast boost LUT = softer look with defined highlights. Experiment with different blend percentages to taste.

Workflow Integration

Export your custom blended LUT as .cube file. Load into your NLE (Premiere, Resolve, FCPX) or camera. Apply to entire footage for consistent look, then fine-tune individual scenes with additional color grading on top.

FAQ

Q: Can LUTs replace color grading?
A: LUTs are a starting point, not final grade. Use them as base, then adjust individual shots for proper exposure and skin tone.

Q: Should I use in-camera LUTs or apply in post?
A: In-camera LUTs are a monitoring assist, not captured in the raw footage. Always apply final LUTs in post-production for maximum control.

Finding the right intensity

Most creative LUTs are built strong so their effect is obvious the moment somebody previews them. That makes them useful for selling a look and frequently too much for using one. Reducing intensity is not a compromise. It is the normal way these are applied in finished work.

Skin is where excess shows first. A look pushing contrast and saturation hard produces faces that read as sunburnt, jaundiced or plastic long before the rest of the frame looks wrong. Judge intensity on a face rather than on a wide exterior, because the audience will.

Different shots from one scene often need different amounts. A look sitting perfectly on a wide shot can be excessive on a close-up where the face fills the frame, and applying one intensity across a sequence is what makes graded footage look mechanically processed rather than considered.

Watch what happens at the extremes. Many LUTs crush shadows and clip highlights as part of their character, and reducing intensity pulls both back toward the original. If a look is only acceptable at full strength but destroys highlight detail there, the problem is the LUT rather than the amount.

Balance the shot before the look, every time. A LUT applied to an unbalanced image bakes in whatever was wrong, and adjusting afterwards means correcting through a transformation already applied. Exposure and white balance first, then the look, then intensity is the order that stays workable.

Vocabulary

LUT intensity. How strongly a lookup table's transformation is applied, expressed as a percentage. Reducing it blends the transformed image back toward the original rather than changing the transformation itself.

Creative LUT. A lookup table applying a stylistic look, as opposed to a technical one converting between colour spaces. Usually built strong so its effect is obvious in a preview, and usually applied at reduced intensity in finished work.

Shadow crush. Where dark tones are pushed to pure black, losing the detail that was there. Common as part of a strong look, and irreversible once rendered, so worth checking before committing.

Skin tone. The colours of human skin, the reference point most viewers judge an image by without realising. The first place an overdone grade becomes obvious, and the reason faces are checked before anything else.
