Selling video LUTs as downloads: the look your buyer applies to footage you have never seen

Every other download seller knows roughly what the buyer will do with the file. A LUT seller does not. Your look was built on your camera, your lenses, your light, your favourite time of day — and the buyer applies it to footage shot on a different camera, in fluorescent office light, at noon, on skin tones you never tested. If it survives that, you have a product. If it only survives your showreel, you have a refund thread with screenshots. The craft of selling LUTs is not making a beautiful grade. It is making a grade that degrades gracefully on footage that was never yours.

The product is a translation, not a filter

Say in the listing, in plain words, exactly what is in the download: how many LUTs, in which formats, at which cube sizes. The working format is .cube — it opens in Premiere Pro, DaVinci Resolve, Final Cut Pro, and most mobile editors. If you also ship .3dl or a camera-specific format, name it separately rather than letting buyers discover it in a folder. Cube size matters to the buyers who know: a 64-point cube interpolates more smoothly than a 16-point one, especially in skies and gradients where banding shows first. Name the size you ship.

Then split the pack the way professionals actually work: conversion LUTs and creative LUTs are different products wearing one name. A conversion LUT takes a specific log profile to a standard colour space and should be judged on accuracy — skin where skin should be, greys that stay grey. A creative LUT is a taste decision stacked on top. Ship them in clearly named folders, say which is which on the listing, and never bake a creative look into a file you have labelled as a conversion. The buyer who cannot separate the two cannot fix either when something looks wrong.

Your preview footage is the lie you have to correct

Every LUT listing shows the seller's best frames: golden hour, clean light, a subject chosen because the look flatters them. The buyer concludes the LUT did that. It did not — the light did most of it, and the LUT will meet their worst-lit footage first: a wedding reception under mixed tungsten and DJ lights, a product shot under an office panel, a vlog in a car at midday.

Correct the lie before the purchase, not in the support thread after it. Show each look on at least three kinds of footage — daylight exterior, indoor mixed light, and a low-light frame — and on more than one skin tone, because a look that holds on one face and turns another green is not finished. Show the ungraded log frame beside the graded one, at the same size, without a beauty crop. And state the exposure the test footage was shot at: a LUT built for correctly exposed log will punish the underexposed footage beginners most often feed it, and the honest sentence "expose for the profile, then apply" on the listing prevents the angriest review in this niche — the one that calls your look broken when the footage was two stops under.

Name the camera, name the profile

A LUT is only correct for the input it was built from. The same look built for one manufacturer's log profile will land wrong — milky, oversaturated, skin shifted — on another's, and "works with any log footage" is the sentence that generates your support load. Name the profiles your pack is built for, camera family by camera family, in the listing and in a compatibility note inside the download: this pack is built for these named log profiles, tested on these cameras, and not tested on the ones you did not touch.

Name the files the same way. The buyer mid-edit searches their LUT browser for the camera in their hand, not for your mood words. A file named for its profile and its look — profile first, look second — gets found and used; a folder of evocative one-word names gets opened once, renamed by the buyer if you are lucky, and abandoned if you are not. Keep the names stable across updates for the same reason every file seller should: a project file references a LUT by its path and name, and a renamed LUT is a missing LUT when that project reopens.

One hundred percent is a starting point, not the product

Almost nobody's footage wants your creative LUT at full strength. Beginners do not know that, apply it at 100%, watch their footage go crunchy and orange, and conclude the pack is bad. Professionals know it and reach for the intensity control — which lives in a different place in every editor, and does not exist under that name in all of them.

Ship the judgement with the files. Either include reduced-strength variants of each creative look, clearly named as the same look at lower intensity, or write the two-line version into the install guide: where the intensity or opacity control is in each major editor, and the range you designed the look to be used at. A look designed to sit at 60–80% should say so. This is the cheapest quality upgrade in the whole product: nothing about the grade changes, and the buyer's first result goes from "too much" to what you intended — because what you intended was never the slider at the top.

The install path is part of the delivery

A .cube file does nothing until it is in the right folder, and the right folder is different in every editor — a LUTs directory inside one application's support folders, a shared folder another application watches, an import inside a third that copies the file somewhere the buyer will never find again. An install guide written for one editor is, for a third of your buyers, a rumour.

Write the install steps per editor, with the actual folder path or import menu for each one you claim to support, and test them on a clean install rather than your own machine — your machine already has three years of accumulated LUT folders and will lie to you about what a first-time buyer sees. Put the guide inside the download as a file that survives outside your store page, and name the version on it. When an editor update moves a folder — and editor updates do — a revised guide shipped to past buyers is a small email that prevents a week of "your update broke my LUTs" messages about a change you did not make.

The licence line LUT buyers actually hit

LUT licensing has one question that generates nearly all the disputes: the buyer is not grading their own holiday video — they are grading client work, paid work, work other people will be credited for. Spell out the operative lines in plain words, in the listing and in a licence file inside the download: use in commercial and client video is allowed, including work the buyer is paid for and work published by their clients; redistributing or reselling the .cube files themselves — in a competing pack, a freebie bundle, or a "10,000 LUTs" compilation — is not; and whether one purchase covers a whole editing team or one seat per editor is your call, but it is the question every small production company will ask, so answer it before they have to email you.

Footage rights deserve their own honesty line in the other direction. Your preview frames are your footage or licensed footage — say so, and never build a listing on frames pulled from someone else's video, however good the grade looks on them. The LUT business runs on before-and-afters; a seller caught grading footage they had no right to use loses the trust the whole listing depends on.

An update that changes the look is a recall

LUT packs grow: you add the looks buyers keep requesting, build the version for the new camera profile everyone just switched to, ship version 2. One rule protects every project your buyers have already finished: never change the look of an existing LUT in an update. A saved project does not store your grade — it stores a reference to your file, and it re-reads that file every time the project opens. Silently "improving" a shipped LUT means a buyer reopening a delivered project for one small client revision finds every shot looking different from the version the client approved.

Add, do not revise. New looks go in under new names; a genuinely better version of an old look ships beside the original, named as the new version, with the original left exactly as it was. Ship the update as the full pack plus a plain-language changelog — what was added, what is new-named, what was deliberately left untouched — and put the pack name, version, and date in a README inside the download so a buyer can tell in ten seconds whether the folder on their drive is current. Announce updates to past buyers with the added looks first: "now includes the profile you asked for, nothing you already use has changed" is the whole pitch, and it is only true if you kept the discipline above.

A short launch checklist for LUT sellers

1. Name the contents in the listing: LUT count, formats (.cube first), cube size, and which files are conversions versus creative looks.
2. Preview honestly: every look on daylight, mixed indoor light, and low light, on more than one skin tone, with the ungraded log frame beside it.
3. Name the input: list the exact camera log profiles the pack is built and tested for, in the listing and in a compatibility note inside the download.
4. Name files for search: profile first, look second, stable names you commit to never renaming in updates.
5. Ship the intensity judgement: reduced-strength variants or per-editor instructions for the intensity control, with the range you designed for.
6. Write the install guide per editor, tested on a clean install, included as a file inside the download with its version on it.
7. Write the licence and the update policy before you need them: client and commercial use yes, raw-file redistribution no, team seats answered — and updates add new files, never change an existing look.

A note on delivery, because every step above ends at a download: I build FileFreight for sellers of files like these — flat-rate digital delivery with licence keys, where you connect your own Stripe account, Pro is $19/month with 0% platform fees (a free tier takes 5%), sales tax and VAT handling stay with you as the seller, there is no LUT importer and no video-editor integration, and it is not a Shopify app. Whatever you deliver with, judge it by the test in this article: your look has to survive footage you have never seen, inside projects you will never open — so the delivery has to carry the profiles, the install guide, and the untouched originals with it.
