How to Write a Video Ad Brief Without Wasting Time

A good ad film starts long before anyone picks up a camera. It starts with a brief. We've seen projects stall for two weeks simply because nobody worked out who the film was actually speaking to. Below is a concrete checklist so that doesn't happen to you.

Why bother with a brief at all

A brief isn't a box to tick. It's a document that saves you money and stress. Without it, the production team guesses: what tone, what length, what to put front and center. Guessing leads to revisions, and revisions cost money. The more you settle on paper before filming, the fewer surprises you'll hit during editing, when changing anything is already expensive and slow.

A brief also helps you. It forces you to answer questions you'd need to answer anyway: why you're making this film, who's meant to watch it, and what should happen as a result.

The film's goal: what should happen after someone watches it

Start with one sentence: what should the viewer do or think after watching. That's not the same as "brand promotion." The goal needs to be specific.

Examples of well-defined goals:

• the viewer clicks a link and signs up for a demo,
• the viewer remembers the company name at a trade show,
• the viewer understands how the product works without reading a manual,
• the viewer starts trusting the brand enough to leave a phone number.

If the brief lists several goals at once, the film usually ends up serving none of them well. Pick one main goal and stick with it. Everything else is a side effect at best.

Audience: who are we talking to

Another mistake we see often: the brief says "all our customers." That's not enough. The more precisely you describe the viewer, the easier it is for the writer and director to pick the right language, pacing, and examples.

Worth describing:

• who this person is, professionally or in their life (a small business owner, a parent of a school-age kid, an IT specialist),
• what they already know about your industry, and what they don't,
• what objections or doubts they have about your product,
• where they'll watch this: scrolling their phone in the evening, or watching a presentation at a business meeting.

That last point leads straight into the next section.

Distribution channel and format

A film for Instagram Reels and a film for the company website are two different jobs, even on the same topic. Different framing (vertical versus horizontal), different pacing, different length, different approach to sound, since on social media a lot of people watch without audio on.

In the brief, list every channel the film will run on, and the priority between them. If the main placement is Reels and TikTok and the website is secondary, that's the order you plan framing and editing around. A single "universal" version almost always turns out weaker than versions built for a specific channel.

Length, tone, and style

Length follows from the channel and the goal, not from how much footage you'd like to fit in. A short social spot usually runs somewhere between ten and thirty-some seconds. A brand film for the website or YouTube can run a minute, two, sometimes more, if the content earns it.

Tone and style are easier to describe with examples than with adjectives. Instead of writing "we want modern and professional" (which every client says), give:

• a brand whose communication style you like,
• a specific film or ad you've seen and would like something in that spirit,
• what to definitely avoid (e.g. humor, sentimentality, fast cuts).

Visual references

This is one of the most underrated parts of a brief. Three links to films you like tell the director more than a page of description. You don't need to name what exactly you like about a given film, sometimes intuition is enough. What matters is pointing to: editing pace, type of music, how the product is shown, color palette.

If you have brand materials (a style guide, sample graphics, previous films), include those too. The crew shouldn't have to guess which shade of blue is yours.

Budget and deadline

Many clients treat budget as confidential information best kept close to the chest. In practice, this makes work harder for both sides. Without knowing the budget, the production team proposes solutions that later need trimming, which costs extra time.

Give a range, even a rough one. A short social spot usually starts at a few thousand PLN (roughly 1 EUR ≈ 4.3 PLN) and goes up, a fully produced brand film usually runs into the tens of thousands of PLN, depending on shoot days, locations, and the number of edit versions. Same with the deadline: give a final date and say whether it's fixed (say, a product launch) or flexible.

Materials to prepare on your end

Before you start writing the brief, gather what you already have. It makes the first meeting shorter and easier for both sides.

What to prepare	Why
Logo and brand guidelines	Consistent colors and typography in the film
Previous video/photo materials	A reference point for style
Product/service information	A script built on facts, not guesswork
List of people to film (if relevant)	Planning shoot days and availability
Access to locations	Sorting out logistics before the shoot

Common mistakes in briefs

• No single goal: the brief tries to cover sales, brand image, and recruitment at once.
• The audience description stops at "our customers," with no specifics.
• No references, but a long tone description made of adjectives.
• Hidden budget, so the first quote misses expectations entirely.
• No clear decision-maker: several people sign off on the brief, each with a different vision, and revisions pile up once they're already expensive.
• A deadline set for "yesterday" with no advance warning to the production team.

A ready-to-copy brief structure

You can copy the structure below into a document and fill it in point by point.

1. Project name and point of contact (who approves the final result)
2. Film goal (one sentence: what should happen after watching)
3. Target audience (who the viewer is, what they know, what objections they have)
4. Distribution channels and priorities (where the film will be published)
5. Format and length (vertical/horizontal, seconds/minutes)
6. Tone and style (examples, not adjectives)
7. Visual references (links to films, brand materials)
8. Key message (one, at most two sentences the viewer should remember)
9. Budget (range)
10. Deadline (final date, fixed or flexible)
11. Client materials (logo, photos, data, locations, people)
12. Constraints (what to avoid: competitors, taglines, legal elements)

Frequently asked questions

How long should a good brief be?

It's not about length, it's about completeness. One page with concrete answers beats five pages of generalities. In practice, a well-filled version of the structure above fits on one or two pages.

Does the brief need to include a finished script?

No, and often it's better if it doesn't. The script is the director's job, built on the brief. If you already have a specific idea for certain shots, it's worth noting as inspiration, but leave room for the production team's own proposals.

What if I don't know the budget yet?

Give the range you're working within, even a very wide one. The production team will then scale the shoot (number of shoot days, locations, number of edit versions) to fit what's realistic, instead of quoting a number up front and then having to cut the budget by force later.

Who on the client side should fill out the brief?

Ideally one decision-maker who then approves each stage. If several people with different visions are drafting the brief, it's worth flagging that upfront and naming who has the final say on approving the script and the edit.

If you'd rather work through this process together, at DOPEST.video we start every production with exactly that conversation: we ask about the goal, the audience, and the budget before proposing a script and a quote.
