LUTs for Video: What They Are and How to Use Them
LUTs are lookup tables that map input color values to output values. In video editing, a LUT can convert a known camera signal or create a particular look. The result depends on the recording’s color profile, the LUT’s expected input and the rest of the color workflow.
What are LUTs in video editing?
A LUT tells an application how to change values representing color and tone. It is a repeatable transform: the same input receives the same mapped output within the defined pipeline. It does not recognize a face, repair focus or decide which part of a wedding shot should draw attention.
A technical LUT might prepare footage recorded in a particular Log encoding for a specified output. A creative LUT might produce warmer highlights, cooler shadows or a different contrast response. Read the intended input and output instead of choosing only by the example image on the download page.
| Two ways to classify LUTs | What the distinction means | What to check |
|---|---|---|
| 1D LUT | Maps channels along one-dimensional curves. | Whether the format and transform suit the application. |
| 3D LUT | Maps combinations of RGB values through a three-dimensional table. | Supported format, input/output assumptions and image quality. |
| Technical or conversion LUT | Has a defined transform within a color pipeline. | Source gamut/gamma, output and conversion already applied. |
| Creative or look LUT | Changes the appearance for a stylistic purpose. | The starting color space it expects and whether it suits the scene. |
These classifications overlap. A 3D LUT can serve a technical purpose or a creative one. “3D” does not mean a spatial effect or a guarantee of better results. The OpenColorIO LUT documentation describes 1D and 3D forms.
Choose a LUT file that matches your footage
Before downloading a LUT pack, write down the recording profile and the delivery you need. Camera brand alone is not enough: two clips from one camera can use different gamma and gamut settings. Phone HDR recordings and standard SDR recordings also require different handling.
- Identify the source. Check metadata, camera settings or the person who recorded it. Do not assume a flat-looking image must be Log.
- Read the expected input. A LUT designed for one Log signal is not automatically compatible with another.
- Check the output. Determine whether it produces a display-ready image, a creative intermediate or another signal.
- Inspect the project. Automatic color management or a previous effect may already perform the same conversion.
- Confirm application support. Check that the editor supports the LUT’s format and the place where you plan to apply it.
A folder labelled “cinematic LUT pack” describes a collection, not compatibility. Keep the instructions with the files so another editor can understand which specific LUTs were used. For manufacturer material, start with the camera maker’s documentation; ARRI’s color FAQ illustrates why look formats and workflows are specific.
How to apply LUTs to video: a practical workflow
1. Check the unprocessed source
Inspect exposure, white balance, skin, highlights and noise before choosing a look. Compare representative shots rather than a single attractive frame. A transform cannot restore detail that the source recording clipped or never captured.
2. Establish the color pipeline
Choose how the source enters the working color space and how the result reaches its output. Use the technical LUT where the workflow calls for it. Avoid combining automatic Log conversion with a second conversion LUT unintentionally.
3. Balance the shot in the appropriate stage
Use exposure and white-balance adjustments in a position that makes sense for the chosen pipeline. An adjustment before a conversion and the same adjustment after it can behave differently. Keep the stages understandable so you can identify which one causes clipping or an unwanted cast.
4. Add the look and compare
Place a creative LUT where it receives the input it expects. If the tool offers a mix or strength control, use it to evaluate the look, not to conceal a fundamentally incorrect transform. Bypass the effect and compare color and tone with the balanced version.
5. Check multiple shots and the export
Review faces, bright fabric, dark areas, saturated lights and transitions between cameras. Export a short sample and check it outside the editor. If the output changes unexpectedly, examine output color settings and viewing conditions before adding another LUT.
Applying LUTs in Premiere, DaVinci Resolve and Final Cut
| Application | Documented route | Important check |
|---|---|---|
| Adobe Premiere | Lumetri Color can load a LUT through Input LUT; current color-management controls also provide source-clip options. | Choose the intended stage and avoid a duplicated source conversion. |
| DaVinci Resolve | LUT application can form part of a node-based grade alongside Resolve’s color-management options. | Know what signal reaches the LUT node and what transform follows it. |
| Final Cut Pro | Camera LUTs and a Custom LUT effect serve different places in the workflow. Apple documents importing supported camera LUT files. | Match the camera/input assumptions and the intended output color space. |
Follow the documentation for your installed version: Adobe: add a LUT, Adobe: source color management, Blackmagic: color workflow and Apple: apply LUTs. Menu labels and supported formats can change.
LUT vs preset vs color grading
| Tool or process | What it provides | What you still need to do |
|---|---|---|
| LUT | A mapping of color values. | Choose compatible input and output, then judge the image. |
| Preset | Saved settings for a particular application or effect. | Check its dependencies, version and starting conditions. |
| Color correction | Adjustments intended to establish a usable, consistent image. | Evaluate exposure, balance and continuity across shots. |
| Color grading | Creative decisions about the finished appearance. | Use the scene, story and delivery as the reference. |
A LUT is one possible tool inside a grade. A complete grade may include tracked or selective adjustments, shot matching and decisions that cannot be reduced to a reusable color table. Start with the problem you need to solve instead of applying an entire collection in sequence.

Why a LUT looks wrong
| Symptom | Possible cause | First check |
|---|---|---|
| Excessive contrast | Wrong expected input, duplicated conversion or an unsuitable transform. | Bypass the LUT and check source, project and output settings. |
| Skin looks orange, green or magenta | Source white balance, lighting or a look that does not suit the scene. | Compare faces before and after each processing stage. |
| Bright detail disappears | Clipped recording or values pushed outside the useful output range. | Inspect the source and the transform, rather than adding sharpening. |
| Cameras still do not match | Different profiles, exposure, lighting or balancing. | Match sources before judging one shared look. |
| Banding or harsh gradients | Source precision, compression, transform or processing limitations. | Compare a clean source sample and a high-quality test export. |
| The export looks different | Output tagging, color settings, player or display differences. | Review the delivery pipeline and test in the intended viewing context. |
Use the same comparison sequence when troubleshooting: source → input handling → balance → creative look → output. Change one stage at a time and keep the version that worked so you can return to it.
Example: matching two event cameras
Imagine a ceremony recorded with two cameras, one in Log and the other in a standard picture profile. Applying the same conversion LUT to both is unlikely to produce a reliable match. Identify the signals, bring them into a consistent working context and balance each shot. Then evaluate a creative look across the sequence.
This is a workflow example, not a claim about a particular client or a guaranteed result. With mixed event lighting, one global setting may still leave individual shots needing attention. Our camera matching guide explains the next steps.
LUT questions
What is a LUT in video editing used for?
It can transform a known source signal or provide a reusable look. The same file can be useful across compatible clips, but it does not automatically correct their exposure or lighting.
What is LUT in video editing terminology?
LUT stands for lookup table. “LUT video” is often used as shorthand for a video treated with a lookup table or for a downloadable LUT intended for video work.
Can I use one LUT with every camera?
Only when its expected input is appropriate for the material reaching it. Check the source profile and existing color-management transforms rather than relying on the camera brand.
Does every editor support LUTs?
No. Applications differ in file-format support, controls and placement in the pipeline. Check whether your version supports LUTs before buying a pack, and test a compatible file first.
Are free LUTs worse than paid LUTs?
Price is not a compatibility or quality test. Look for clear input/output documentation, useful examples and terms that fit the intended work. A paid collection can still be inappropriate for your footage.
Can a LUT replace color grading?
It can contribute to a grade. It does not replace shot-by-shot judgment, selective correction, continuity and checking the final delivery.
