What a Commercial Brief Actually Asks You to Make

Why this matters

A commercial is not a film about a product. It is an argument for a product, delivered in 15–60 seconds, to an audience that did not ask to see it. Every ad that has ever worked had a single job it was asked to do — launch a brand, shift a perception, drive a click — and every decision in production either served that job or it didn't. AI tools collapse the cost of making pretty images, which makes the brief even more load-bearing. Without a sharp brief you will generate 200 beautiful clips that don't sell anything. Learn to read and write the brief first; everything else is execution.

Demo

The canonical creative brief has ~8 fields: Client, Product, Objective (awareness / consideration / conversion), Audience (one specific person, not a demo segment), Insight (a true thing about the audience that the product answers), Proposition (the one-line promise), Tone, Mandatories (logo, endframe, legal). The 'one-line promise' is the seed from which the whole commercial grows. If the brief has three propositions, the ad will fail — pick one.

# Creative brief template
 
Client:            [brand]
Product:           [the thing being sold]
Objective:         [awareness | consideration | conversion | loyalty]
Audience:          [one person: name, age, context, what they already feel]
Insight:           [one true sentence about that person's life]
Proposition:       [one-line promise the product makes against that insight]
Tone:              [3 adjectives, no filler]
Mandatories:       [logo lockup, endframe duration, legal/super requirements]
Deliverables:      [1x :30 hero, 2x :15 cutdowns, 4x :06 bumpers, :09 vertical Reel]
Channels:          [where it lives: TV, pre-roll, Reels, IG feed, OOH, CTV]
KPI:               [how success is measured]
 
Example — "the whole ad in one sentence":
  "Tell busy parents that [BRAND] breakfast takes 2 minutes, not 10,
   so their morning feels like victory, not chaos."

Try it yourself

1. Pick an ad you actually remember (or hated). Reverse-engineer its brief: what was the single proposition? Who was the audience? Why did it work or not? You should be able to write all 8 fields in under 10 minutes — if you can't, the ad was doing too many jobs.
2. Write a brief for a made-up product — a new instant coffee, a savings app, a delivery service. Constraint: the proposition must be one sentence, and the audience must be a specific person, not a census bracket.
3. Take one brief and write THREE different propositions for the same product. Shoot an 8-second pre-viz for each. Notice how a change in proposition changes the entire visual approach.
4. Read 3 Cannes Lions case studies (Film Craft category). Note how the brief is stated up front in every one — it is the single thing every craft decision is defended against.
5. Audit your own AI-generated ads from the past year: did each start from a brief, or from 'something that would look cool'? The first kind sells; the second kind is a portfolio piece.
