How to Brief a Video Production Agency
The quality of a video production brief determines the quality of everything that follows it.
Not entirely. A great agency brings creative thinking that a brief cannot prescribe. A brief that clearly articulates what you're trying to achieve, who it's for, and what success looks like gives a creative team the foundation to do genuinely ambitious work. A vague brief almost always produces vague or can miss the intended 'target' -regardless of how talented the team producing it is.
Yet briefing is one of the most consistently underprepared parts of the commissioning process. Many clients come with a rough idea, a budget range, and a deadline - and assume the agency will fill in the rest. Sometimes they can. But every gap in a brief is a place where assumptions silently enter the process, and assumptions are the most common source of expense later on.
Why a Brief Matters More Than Most Clients Realise
A brief will be the document that aligns everyone involved on what the project is actually trying to do before any creative development begins, before any budget is committed, before any creative team invests time in a direction that might not be what you need. As said - get it down on paper!
A brief forces the most valuable part of the process. Working out your objective precisely, articulating your audience specifically, and confronting what success looks like in measurable terms are all disciplines that improve not just the brief but your clarity about what you actually want. The organisations we work alongside consistently find that clients who invest seriously in the briefing process end up with better work, not because the brief constrains creativity but because it gives creativity a precise problem to solve.
A brief is a launchpad. The creative team can approach the solution with a clear ambition.
The Complete Brief
1. The objective - What needs to be acheived
Start with the single most important thing this video needs to do. Not a list of everything it might do - the one thing that, if it achieved nothing else, would make the project a success.
Template prompt
What is the primary objective of this video?
e.g. Build awareness of our rebrand among UK marketing directors / Drive enquiries for our new service line / Recruit graduates to our graduate programme
What does success look like - and how will you measure it?
e.g. 500 qualified leads within 3 months of launch / 10,000 views on LinkedIn / increased direct traffic to the contact page
2. The audience
Be as specific as possible. "UK businesses" is not an audience. "UK-based marketing directors at professional services firms with 50–500 employees, who are sceptical of video production costs and need to justify spend internally" is an audience. The more precisely you can describe the person watching, the more precisely the creative team can calibrate every decision toward them.
Template prompt
Who is the primary audience for this video?
Role, sector, location, mindset, relationship to your brand (aware / unaware / considering)
What does this audience currently think, feel, or believe about your brand or category and what do you want them to think, feel, or believe after watching?
The gap between these two states is the job the video needs to do
3. The message
Distinguish between your primary message > the single most important thing you want the audience to take away < and secondary messages, which support but don't lead. A video that tries to communicate seven things with equal weight communicates none of them memorably. Hierarchy matters.
Template prompt
If the audience remembers only one thing after watching, what should it be?
One sentence. If you can't write it in one sentence, it isn't clear enough yet.
What supporting messages matter, but are secondary to the above?
List up to three.
4. Tone and creative territory
Tone is one of the most commonly underdefined elements of a brief and one of the most consequential. "Professional but approachable" describes almost every B2B brand and tells a creative team almost nothing useful. Try to be more specific: what does the tone sound like, feel like, and crucially, what does it definitely not sound like?
Template prompt
How should this video feel to watch?
Three adjectives and three adjectives that describe what it must not feel like
Reference content, what have you seen that feels right, and what feels wrong?
Links, examples - "Wrong" references are often as useful as right ones.
5. Practical parameters
The creative constraints that are easy to overlook but expensive to discover late: format requirements, platform specifications, broadcast standards, brand guidelines, legal restrictions, and any mandatory inclusions (product shots, regulatory disclaimers, specific spokespersons).
Template prompt
Where will this video be used, and in what format?
e.g. Website hero (landscape), LinkedIn feed (square and landscape cuts), broadcast TV (16:9, Clearcast approved)
Are there any mandatory inclusions or restrictions?
Brand guidelines, legal sign-off requirements, product/people that must or must not appear
What approvals process will this go through internally before sign-off?
Knowing this upfront prevents timeline surprises later
6. Budget and timeline
These are the two elements clients most often withhold and the two that most affect what's possible. An agency that doesn't know your budget cannot tell you whether your expectations are realistic, which wastes everyone's time. A range is fine; no figure at all is not.
Template prompt
What is the production budget for this project?
A range is fine. If you're unsure, say so and ask the agency to outline what's achievable at different investment levels.
When does the finished video need to be ready, and are there any fixed milestones before that date?
e.g. Script approval by X / shoot must be complete by Y / launch tied to an event on Z
What to Do With the Brief Once You Have It
A brief is a starting point, not a contract. Share it with the agency before your first meeting so they have time to think and come to that meeting ready to be questioned on it. The best agencies will push back on parts that are unclear or contradictory, ask for more specificity where it matters, and use the brief as a springboard for a creative conversation rather than a checklist to tick off.

FAQs
Do I need a fully complete brief before approaching a video production agency?
No and insisting on a complete brief before any conversation can sometimes prevent the most useful thinking from happening. What you do need before approaching an agency is clarity on your objective and a sense of your budget and timeline. Everything else can be developed collaboratively.
How long should a video production brief be?
As long as it needs to be to answer the key questions clearly and no longer. A two-page brief that is precise and well-considered is more useful than a ten-page document full of background material that doesn't help a creative team make better decisions.
What happens if my brief changes after the project has started?
Brief changes mid-project are common and not inherently problematic, circumstances change, and well planned production companies are accustomed to navigating that. What matters is that changes are communicated clearly and early, and that both parties understand the implications for timeline and cost. A well-structured contract or comms will define what constitutes a scope change and how those are handled, which is worth discussing and agreeing before production begins rather than after.
