In the quiet, precise world of post-production color work, a new tool has arrived to fill a gap that many colorists have long navigated around. Cut Point Labs, releasing LUT Tuner for macOS in mid-2026, offers those who shape the visual tone of film and video a focused instrument — one that lets them inspect, adjust, and export color lookup tables without the weight of a full grading suite. It is a small but meaningful act of craft-respecting design: giving specialists exactly what they need, and nothing more.
Cut Point Labs Launches LUT Tuner for Mac Post-Production Workflows
Tweak a LUT without opening a full grading project
Mark
Why does a colorist need a separate tool just to edit a LUT? Wouldn't the grading software they already use handle this?
Mimi
Grading software is built for full color correction workflows—it's heavy, it requires a project structure, it takes time to load. If you just need to tweak a LUT or verify how it behaves on a specific shot, opening all that feels like overkill. LUT Tuner is purpose-built for that moment.
Mark
So this is really about speed and focus.
Mimi
Exactly. You're not color grading a scene. You're inspecting a tool—a LUT—and making small adjustments to it. The interface gets out of your way and lets you see the curve, make the change, and move on.
Mark
What about the preview options? Why does it matter that you can test against video, stills, and patterns?
Mimi
Different LUTs behave differently depending on what you throw at them. A creative look might crush blacks in a way that works for one shot but breaks another. Being able to quickly test against your actual footage—or against a known test pattern if you're troubleshooting—tells you whether the LUT is doing what you expect.
Mark
And the export is just a standard .cube file?
Mimi
Yes. It's not locked into any proprietary format. You edit it, export it, and it works in any grading software that reads .cube files. That's the whole point—it's a utility, not a walled garden.
Mark
Who benefits most from this?
Mimi
Teams that manage shared color looks across projects, DITs who need to verify LUTs on set, finishing artists who inherit LUTs from other colorists and need to adjust them without opening a full project. Anyone in the pipeline who touches color but isn't doing full-scene grading.
Der Puls
- Color professionals have long faced an inefficiency — opening heavyweight grading software just to inspect or tweak a single LUT file wastes time and disrupts momentum.
- LUT Tuner arrives as a purpose-built macOS tool that lets colorists load, preview, edit, and export .cube 3D LUT files in a focused, single-purpose interface.
- The app supports a wide range of media formats and codecs, offers curve-based editing with per-channel control, and uses tetrahedral interpolation for color-accurate previews.
- Teams managing shared color looks across multiple projects can now inspect and adjust LUTs independently, potentially tightening handoffs and reducing turnaround friction.
- The tool is currently landing as a lightweight but capable alternative for post-production pipelines where speed and precision matter more than feature breadth.
In the quiet, precise world of post-production color work, a new tool has arrived to fill a gap that many colorists have long navigated around. Cut Point Labs, releasing LUT Tuner for macOS in mid-2026, offers those who shape the visual tone of film and video a focused instrument — one that lets them inspect, adjust, and export color lookup tables without the weight of a full grading suite. It is a small but meaningful act of craft-respecting design: giving specialists exactly what they need, and nothing more.
Cut Point Labs has released LUT Tuner, a macOS application designed for the practical, often unglamorous work of color grading in post-production. The premise is simple but valuable: open a standard .cube 3D LUT file, preview how it behaves on your footage, make targeted adjustments, and export a clean result — all without launching a full grading project.
The app is built for colorists, editors, finishing artists, and digital imaging technicians who need to inspect and modify LUTs quickly. The workflow centers on loading a .cube file, choosing a preview source — a still image, a video clip, or a generated test pattern — and viewing the LUT's response curve on screen. Editing is curve-based, with the ability to work in individual RGB channels or in combination, and includes radius-based neighboring influence so adjustments ripple naturally to nearby points. Keyboard nudging, full undo and redo, and a reset-to-original option round out the precision controls.
Media support is broad: still formats include PNG, JPEG, TIFF, EXR, DPX, and HEIC, while video support spans ProRes, DNxHD/HR, H.264, HEVC, AV1, CineForm, and more across .mov, .mp4, and .mxf containers. The app defaults to tetrahedral interpolation for accurate color preview, with trilinear available for comparison. When edits are complete, users export a standard .cube file and can compare against the original or bypass the LUT entirely to view raw media.
The release speaks to a real gap in professional workflows. Full grading software is powerful but carries significant overhead — opening a project just to verify a LUT's behavior is often more friction than the task warrants. LUT Tuner occupies a lighter, more deliberate space, offering enough control for meaningful work while keeping complexity out of the way.
Cut Point Labs has released LUT Tuner, a macOS application built specifically for the practical work of color grading—the kind of work that happens in post-production when you need to adjust a look quickly without firing up a full grading suite. The tool lets you open a standard .cube 3D LUT file, see exactly how it will behave on your footage, tweak it if needed, and export a clean version, all within a focused, single-purpose interface.
The software is aimed at colorists, editors, finishing artists, and digital imaging technicians—the people who work in post-production pipelines and need to inspect and modify LUTs without the overhead of launching a complete grading project. The workflow is straightforward: you load a .cube LUT file, choose what you want to preview it against (a still image, a video clip, or a generated test pattern), and the app displays the LUT's response curve on screen. From there, you can make targeted adjustments using curve-based editing controls.
The editing interface offers several modes for precision work. You can adjust individual RGB response points or gang them together, working in red, green, or blue channels independently or in combination. The app includes radius-based neighboring influence, which means adjustments to one point can affect nearby points in a controlled way. Full undo and redo are available, along with keyboard nudging—you can move points in precise increments using Shift and Option keys for half-step and quarter-step adjustments respectively. If you make a mess of things, you can reset to the original at any time.
Preview flexibility is central to the design. LUT Tuner can display generated ramps and test patterns, or you can load your own media through a single open-media workflow. For still images, it supports PNG, JPEG, TIFF, EXR, DPX, and HEIC formats. Video support includes .mov, .mp4, and .mxf containers with a broad range of codecs: ProRes, DNxHD and DNxHR, H.264, HEVC, MPEG-2, AV1, VP9, CineForm, JPEG 2000, and uncompressed video. (ProRes RAW is not supported.) The app uses tetrahedral interpolation by default for accurate color preview, with trilinear interpolation available if you want to compare how the LUT behaves under different calculation methods.
Once you've made your edits, you can compare your work against the original LUT or bypass the LUT entirely to see the raw media. When you're satisfied, you export a clean .cube file conforming to standard 3D LUT structure. The tool handles common identity, creative-look, display, and technical transform LUTs, and the export uses whatever LUT size is shown in the interface at the time of export.
The release addresses a real gap in post-production workflows. Color grading software is powerful but heavy—opening a full project just to tweak a LUT or verify its behavior can be inefficient. LUT Tuner sits in that lighter-weight space, offering enough control and visibility to do meaningful work without the complexity. For teams working across multiple projects or managing shared color looks, the ability to inspect and adjust LUTs independently could streamline handoffs and reduce turnaround time.
