How to brief a video agency (with a fill-in template)

Why the brief matters more than most clients expect

An agency can only price and plan against what you tell them. A brief that says 'we need a video for social media' forces the agency to guess at goal, audience, length, and tone — and every guess they get wrong shows up later as a revision request, which costs both sides time. A brief that states the goal, audience, and constraints up front lets the agency propose a concept that is right on the first pass far more often.

The brief template

Work through these in order. Each answer should be a sentence or two — a brief does not need to be long to be useful.

1. Goal — what should this video accomplish? (e.g., drive awareness for a launch, explain a product feature, support a sales conversation, recruit talent.) Be specific about the business outcome, not just 'get views'.
2. Audience — who is watching this, and what do they already know or believe before they see it? Include relevant context like platform habits or where in the buying journey they typically are.
3. Core message — if the viewer remembers only one thing, what should it be? Keep this to a single sentence; a video trying to say five things usually says none of them clearly.
4. References — link two or three videos (yours or others') that show the tone, pacing, or style you're drawn to, and say specifically what you like about each one rather than just 'like this'.
5. Must-haves — any non-negotiable elements: specific messaging that legal or leadership requires, a tagline, a call to action, brand guideline constraints, accessibility requirements (captions, for example).
6. Platforms and formats — where will this run (Instagram, TikTok, YouTube, website, a pitch deck, a trade show screen), and what aspect ratios and lengths does that require?
7. Timeline — when does the final video need to be live, working backwards to a realistic shoot date and pre-production window.
8. Budget range — even an approximate range helps the agency propose a concept that is achievable within it, rather than pitching something that gets cut down later.
9. Approvals — who signs off at each stage (concept, rough cut, final cut), and how many people need to weigh in? Fewer approvers generally means a faster process.

Common mistakes in a first brief

• Leading with visual references instead of the goal — 'make it look like this' without saying what the video needs to achieve leaves the agency unable to judge whether a concept will actually work.
• Naming multiple goals as if they were one — awareness, conversion, and recruiting are different videos with different pacing and messaging; trying to serve all three in one video usually serves none well.
• Skipping the audience description — 'everyone' is not an audience; the more specific the description, the sharper the creative can be.
• Providing no budget range and expecting the agency to guess — this either produces a lowball concept that gets rejected, or an ambitious one that gets cut down, both of which waste a round of work.
• Too many approvers with no single decision-maker — this is the most common cause of scope creep and missed timelines after the shoot is complete.
• Waiting until the rough cut to introduce a new must-have — anything that must be in the video should be flagged in the brief, not discovered during review.

What happens after the brief

Once an agency has a complete brief, the process typically moves through a few defined stages.

1. Concept and quote — the agency proposes a creative direction and a scoped price, often as one or two concept options rather than a single fixed idea.
2. Pre-production — once a concept is approved, the agency locks script, storyboard, casting, locations, and shoot schedule.
3. Production — the shoot itself, over one or more days depending on scope.
4. Post-production and review — editing, with review rounds at agreed checkpoints (rough cut, then final cut) rather than open-ended back-and-forth.
5. Delivery — final files in the agreed formats and aspect ratios, plus any raw footage or source files if that was part of the agreement.

Knowing this sequence in advance helps set expectations about when your input is needed and where in the process changes are cheap versus costly — a change during concept review is far less disruptive than a change requested after the shoot.

A worked example of a filled-in brief

Seeing the template applied makes it easier to write your own. A short example, for a fictional SaaS company launching a new feature:

1. Goal — drive product-page sign-ups from existing free-tier users during the launch week.
2. Audience — free-tier users who have been active in the last 30 days but haven't upgraded; they already know the product, so the video doesn't need to explain the basics.
3. Core message — the new feature removes a specific, named point of friction users have been asking about.
4. References — two competitor product-update videos, noting specifically that we like the fast pacing and on-screen UI capture, not the voiceover style.
5. Must-haves — a specific upgrade CTA and URL on screen for the last 3 seconds; captions burned in for sound-off viewing.
6. Platforms and formats — vertical for in-app placement and Instagram Stories, horizontal for the website and YouTube.
7. Timeline — final video live 3 days before the feature launch date, working back to a shoot date roughly two weeks earlier.
8. Budget range — a stated approximate range so the agency can scope crew and post-production time realistically.
9. Approvals — one product marketing lead as the single sign-off point, with legal reviewing only the on-screen claim before final delivery.

Notice that most of the value here comes from specificity, not length — each line answers a real question the agency would otherwise have to guess at.

How briefing changes for an ongoing content relationship

A one-off project brief and a brief for an agency you work with regularly don't need the same level of detail every time. Once an agency has produced a few pieces for you, they already understand your brand voice, typical approvals, and platform mix, so later briefs can often be shortened to what's different about this specific piece — the goal, the message, and any new must-haves — rather than restating the full template each time. It's still worth revisiting the full template periodically, especially when the goal type changes (moving from awareness content to a recruiting video, for example), since assumptions that held for one goal don't always transfer to another.

Signs a brief needs more work before sending it

A quick self-check before sending a brief to an agency: if you can't answer the goal question in one sentence, or if two people on your team would describe the audience differently, the brief likely needs another internal pass before it goes out. Sending a brief with internal disagreement baked into it usually surfaces later as a confusing round of conflicting feedback once concepts come back, which costs more time than resolving the disagreement upfront would have.

• If the goal sentence still has 'and' in it connecting two different outcomes, split it — pick the primary goal and note the secondary one as a nice-to-have.
• If the audience description could describe almost anyone, narrow it using something specific you know about your customers — a stage in their journey, a stated concern, a channel habit.
• If must-haves aren't finalized internally yet, say so in the brief rather than guessing, and note when they'll be confirmed so the agency can plan around it.
