How to Write a UGC Creative Brief

The most common briefing failure is not vagueness. It is over-specification: a three-page document with every line of dialogue written out, handed to a creator whose entire value is sounding like a real person.

What is a brief actually for?

A brief exists to make the resulting video readable as a test. That is the whole job.

If a video wins, you need to know what won. If it loses, you need to know what lost. Everything in the brief should serve that, and anything that does not is either noise or an unnecessary constraint on someone you hired for their judgment.

This is a different purpose from the one most briefs are written for. Most are written to control the output, which produces videos that match the document and convert at nothing, because the document was written by someone who is not the audience.

There is a second job, and it is the one that makes briefs worth writing at volume: a good brief is reusable. If the angle, hook and must-show are separable fields rather than prose, you can hold four of them constant and change one, which is how a set of briefs becomes a test rather than five unrelated videos.

The version most teams write cannot do that. A narrative brief describing the vibe, the audience and the brand’s aspirations produces a video that is unrepeatable by design, because nobody can tell which part of the description the creator responded to.

What must a brief contain?

Five things, and nothing else needs to be in there.

One angle. A single claim the video is making. “This saves you two hours a week.” Not three claims, not a feature list. Briefs covering multiple angles produce videos testing none of them cleanly, and at a roughly 5% win rate most videos lose. A losing video that tested three things at once teaches you nothing, which means you paid for it twice: once to make it and once in the information you did not get.

The opening three seconds. This is the one place to be prescriptive. Specify the opening line or visual, because it determines whether anything else in the video is seen at all. The working benchmark is a 30%+ hook rate, and that number is decided here and nowhere else. Give the creator the opening, give them two alternatives if you have them, and let them own everything after.

What must be on screen. The product, doing the thing. Specify whether it is physical demonstration or screen recording, which state or screen has to appear, and whether a before-and-after is required and what “before” means. This is the section brands under-write most often, and it is why so much UGC describes a product without ever showing it working.

The non-negotiables. Claims that must be made exactly as written, claims that must not be made, legal disclosures, pricing accuracy, competitor mentions, anything category-regulated. Keep this list genuinely short. Every item is a constraint on natural delivery, and a long list produces a video that sounds like a compliance document, which is precisely the register UGC exists to avoid.

The technical spec. Unglamorous and it prevents most re-shoots: aspect ratio, target length, whether they speak to camera, audio requirement, lighting and framing basics, delivery format, and raw files rather than just the edit.

What should you leave out?

The script. Specify the opening and the points that must be covered, then let them use their own words. Scripted dialogue produces creators reading rather than talking, and viewers detect it instantly even when they cannot name what is wrong. This is the single largest difference between UGC that performs and UGC that looks like an advertisement shot on a phone.

Brand voice guidelines. Those were written for your marketing team, not for someone speaking to camera. They flatten exactly the quality you are paying for, and a creator following them sounds like a brand, which defeats the purpose of hiring a person.

Anything you would rather have their judgment on. Setting, wardrobe, props, time of day. If it does not affect what the video is testing, it is not your call, and specifying it wastes the one thing a creator brings that you cannot.

One more thing to cut: the explanation of why the product matters. Brands routinely open a brief with three paragraphs of positioning, and creators read it as context for the performance rather than as content for the video. What comes back is a creator explaining a value proposition, which is the exact register that fails on short-form.

If a fact needs to be in the video, put it under MUST SAY. If it does not, leave it out entirely. The middle ground, where background information is provided in the hope it will inform the tone, mostly produces videos that sound like someone reciting a briefing.

How long should a brief be?

One page.

If a brief runs past a page, it is usually specifying performance rather than outcome. Length reduces the creator’s judgment without improving the result, and it makes briefs slow to write, which matters more than it sounds. A briefing process has to sustain roughly one new ad per $3,000 of monthly spend. A brief that takes an hour to write becomes a bottleneck at any real volume, and the volume is what produces winners.

Short briefs also fail more usefully. When a one-page brief produces a bad video, you can see which of the five elements was wrong. When a three-page brief does, the cause is buried.

The one-page constraint also protects the creator’s contribution in a way that is easy to miss. Every additional sentence is a decision taken away from the person actually on camera, and the accumulated effect of a long document is a performance assembled from instructions rather than delivered.

There is a reasonable exception. Regulated categories genuinely need longer MUST NOT lists, and no amount of brevity should override a compliance requirement. Even there, the fix is usually a standing one-page compliance appendix attached to every brief rather than a longer brief each time, so the creative half stays short.

What does a working structure look like?

ANGLE       One sentence. The claim this video is testing.
HOOK        The opening line or visual. Alternates if you have them.
MUST SHOW   What appears on screen, and in what state.
MUST SAY    Exact claims required. Keep short.
MUST NOT    Claims, comparisons, disclosures.
SPEC        Ratio, length, audio, delivery, raw files.
DUE         Date. Not "ASAP".

Seven lines. Every one serves either the test or the delivery, and nothing else is in there.

The DUE line matters more than it looks. “ASAP” is not a date, it deprioritises you against every creator’s other work, and it removes your ability to hold anyone to anything. A real date, set against your testing cycle rather than your hope, is the difference between a schedule and a wish.

Two fields do more work than the rest. ANGLE is what makes the result readable, because it is the single variable the video is testing. HOOK is what determines whether the result exists at all, because a video nobody watches produces no data about the angle.

Everything else on that list is either a guardrail or a delivery detail. If you are short of time, write those two properly and let the rest be terse. A brief with a sharp angle and a specified hook, and one-line answers everywhere else, outperforms a thorough document with a vague angle every time.

The short version

Specify the outcome and the constraints. Leave the performance to the performer. One angle per brief, one page per brief, and the first three seconds written down, because everything else in the video depends on them.
