How to Brief a Video Agency (With a Free Template)

A third of marketing budgets is wasted because of poor briefs. That was the finding when the BetterBriefs Project and the IPA surveyed over 1,700 marketers and agency people across 70+ countries, and it puts the global cost of bad briefing north of 200 billion dollars a year. So learning how to brief a video agency properly is not admin. It is the highest-return ten minutes in your production budget. Here is exactly what to send, with the same one-page video brief template we use with our own clients. No download gate, no email capture. It is all on this page.

Why most video briefs fail

Most briefs fail because of a perception gap nobody talks about. In the BetterBriefs research, 80% of marketers believed they write good briefs. Only 10% of agencies agreed. On strategic direction the gap is even worse: 78% of marketers think their briefs provide clear strategy, and just 5% of agencies agree (BetterBriefs and IPA, 2021).

The cost of that gap is rework. Around 69% of marketers and 73% of agencies say rebriefing is a regular occurrence, and every rebrief burns days from your timeline and goodwill from your team. And here is the strange part: roughly nine in ten people on both sides agree the brief is one of the most valuable tools in marketing, and one of the most neglected. Everyone knows it matters. Almost nobody does it well. Which is genuinely good news for you, because a clear one-pager instantly puts you ahead of most of the industry.

This matters more than ever because more brands are commissioning than ever: 91% of businesses now use video as a marketing tool (Wyzowl, 2026), and around a quarter of companies outsource video creation to freelancers or agencies (Wistia, 2026). A lot of people are briefing an agency for the first time. This guide is for them, and for anyone whose last project came back not quite right.

What a video agency actually needs from you

Six things: the job, the audience, the message, the budget, the deadline and the deliverables. Everything else is helpful colour. If your brief nails those six, any decent agency can take it from there.

Notice what is not on that list: the idea. You do not need a concept, a script or a shot list. That is what you are paying the agency for, and over-specifying the execution is one of the fastest ways to get a worse film (more on that in the mistakes section). Brief the problem, not the solution.

There is one question Gully wishes more clients would ask alongside the brief: “if we gave you this budget with no deliverables in mind, what would you come up with?” We think about every brief that way regardless, interrogating it with a fresh perspective rather than taking it as gospel, and often helping the client work out how many deliverables the brief really needs. A brief is the start of a conversation, not a purchase order.

And be ready to hold up your end afterwards. The projects that run smoothest are the ones where the client commits to what they agreed: feedback on time, decisions from the right people, and one consolidated set of notes per round. Put those names and dates in the brief itself.

The video brief template (free, straight from this page)

Here is the video brief template we wish every new client used. Ten fields, one page. Copy it into a doc, fill it in, send it. If a field genuinely does not apply, say so rather than deleting it, because “no budget agreed yet” is useful information too. Call it a video project brief, a creative brief or a video production brief; the shape is the same.

That is the whole template. The BetterBriefs researchers found 89% of marketers and 86% of agencies agree it is hard to produce good work without a clear brief, so those ten fields are doing more for your final film than any amount of feedback later will.

Then do not just email it. Book 30 minutes and talk it through, because the conversation around a brief is where the good stuff surfaces: the context you forgot to write down, the internal politics, the thing your CEO said in the lift. Most video projects are driven by internal priorities like company goals and product launches (over half, per Wistia’s 2026 data), and a quick conversation is usually where the real objective behind the stated one shows up. It is also the moment to agree what success looks like for both sides. Clients rarely raise that unprompted, so we ask it ourselves at the start of every project, and the projects where it gets answered are the ones that end with a happy wash-up rather than a shrug.

Budget: the part everyone avoids

Put the budget in the brief. We know the fear: “if I tell them the number, they will spend all of it.” But withholding it does not save money, it just forces the agency to guess the scale of the answer, and guessing is where projects go wrong. When someone tells us “we need a video”, the first thing Gully asks back is not about the creative at all.

“

Honestly, it’s what’s the budget, because depending on what the budget is will be the way that we scope it up. We can do ambitious projects on small budgets or big budgets, but it’s really important to be transparent and open about the budget at the start of the project.

The budget decides how a job is crewed, who is put on it, and which creative routes are even on the table. For calibration: professional UK productions run from about £5,000 to £200,000, and most of our projects land between £10,000 and £40,000. We broke the bands down line by line in our UK video production cost guide, which is worth reading before you set the number.

And if the number and the ambition do not match? A good agency says so up front. We have turned down projects where the creative was worlds away from the budget, because taking them on would only let the client down later. That candour is a feature. Treat it as one when you hear it.

Deliverables and timings: work backwards from launch

Think in assets, not “a video”. One production can feed a whole quarter of channels if it is planned that way: our Revolut campaign with Grace Beverley delivered 50 deliverables from a single job. Nobody watches the same export twice, so a hero film plus platform-native cutdowns for TikTok, Reels, Shorts, LinkedIn and paid placements is the shape of most modern briefs. List the platforms in field 7 and let the agency propose the exact matrix, because what works on each platform differs more than most brands expect.

On timings, work backwards from the launch date and be honest about approvals. As a rule of thumb from our own production data, a properly planned project wants around three weeks of pre-production and two weeks of post-production, and a fast turnaround can compress to about 10 working days from brief to broadcast when everyone is decisive. The single biggest timeline killer is not the shoot. It is feedback rounds with too many voices, which is why the template asks you to name your decision makers up front.

Usage belongs here too. Say where the work will run (organic, paid social, TV, events, internal) and for how long, because talent, music and stock licensing all scale with usage, and adding it retrospectively always costs more than briefing it at the start.

Briefing mistakes that cost you money

Five patterns come up again and again, and every one of them has a cheap fix.

Prescribing the execution. “We want a drone shot of the office at sunrise” is a shot request, not a brief. Brief the outcome and let the team that makes films for a living find the best way there. The creative brief video agencies actually want to receive describes a problem worth solving.

Hiding the budget. Covered above. It does not create negotiating power, it creates a wrong-sized proposal and a fortnight of back and forth.

Briefing by committee. If six stakeholders each add a “small thing”, the single message in field 6 becomes four messages, and a film that says four things says nothing. One owner writes the brief.

No success measure. “Make something great” feels generous but it is unjudgeable. Give the work a number: views are fine, actions are better.

Fire and forget. The brief is a living agreement. When something changes (budget, launch date, a legal note) update the agency the day you know, not at the review. Remember those rebrief figures: most rework traces back to a brief that quietly changed.

What a good agency does with your brief

Expect questions. That is the tell. An agency that reads a loose brief and simply says “no problem, here is a price” is either not paying attention or pricing in a lot of guesswork you will pay for later. When a brief lands with us, we pull it apart with a fresh perspective, sense-check the deliverables list against the objective, and come back with the questions that shape the scope: who signs off, where will this run, what does success look like in numbers.

Then you should receive two things: a creative response that shows the thinking, and an itemised quote you can compare line by line with any other agency’s. If either is vague, push. (Our cost guide shows what an honest breakdown looks like.)

A brilliant brief does not guarantee a brilliant film, but a bad one nearly guarantees an average one, and the difference is a single page of honest answers. Write the ten fields, share the real budget, name your decision makers, and send it to a video production team that asks good questions back. Or skip straight to the conversation and talk to us. We find the fun in a good brief, and we find it faster when field 8 has a number in it.
