My client called on a Friday afternoon, two days after we delivered the first cut.
She was polite. She said it looked great. Then she said: "It's just not quite what I had in my head."
Those seven words are the most expensive sentence in video production. I have heard a version of them more times than I should admit, and each time I go back through the pre-production process looking for the moment where two different pictures of the film were allowed to coexist without anyone noticing.
That call was three years ago. The client ran communications at a financial services firm. She had given us a two-page brief: professional, well-organised, covering tone of voice, key messages, and the three clients she wanted to feature. She had sent a link to a competitor's film as a reference point, with the note: "Something like this but warmer."
We made something warm. She had imagined something intimate. Both of those words were doing work that neither of us had examined.
The distinction between warm and intimate sounds academic until you watch two films built around each idea. Warm meant open-plan offices, natural light, smiling team members in motion. Intimate meant one person in a quiet room, speaking directly to camera, without B-roll. The reference film she had sent us fell into the second category. We had watched it and taken the palette; we had missed the structure entirely.
The fix was straightforward once we saw it. The recut took a day. But the week of unease it came from, the client's quiet disappointment and our scramble to understand it, that cost was invisible in the invoice.
The brief is a translation exercise
When a client gives a video team a brief, they are describing a film that exists only in their head. The job of a good brief is not to describe what the film should look like. It is to give the production team enough information to build the same film independently.
Most briefs do not do that job. They describe a feeling ("premium"), a tone ("human, but professional"), a length ("around two minutes"), and a purpose ("explain what we do"). Each of those descriptors can sustain a dozen different interpretations. The team that receives the brief picks the one that seems most likely and runs with it. If they picked correctly, nobody notices. If they picked wrong, you hear about it on a Friday.
The fix is to treat a brief as a translation exercise. The production team needs to translate your internal picture into an external object. The more information you give them about the original, the closer the translation will be.
The question that sharpens everything
There is a question I ask every client before we start a new corporate video london commission, and it changes how I hear everything that follows. The question is: who is the one person you most want to watch this film, and what do you want them to do when it ends?
Not the audience. One person. The buyer who has been evaluating options for six weeks. The new joiner who is quietly wondering if they made the right call. The board member who will see it in a presentation and form an opinion nobody talks about but everyone knows matters. When you name that person, the brief becomes specific almost by accident. The tone, the running time, the structure, all of it flows from knowing exactly who needs to be persuaded and of what.
The second question is: what does that person believe right now, and what do you need them to believe after watching? This is different from "what are our key messages." Key messages are what you want to say. The belief shift is what the film needs to achieve. They are often not the same.
A client who wants to "showcase expertise" is describing a key message. When I ask about the belief shift, the answer is usually something like: "They think we are competent but not creative. We need them to believe we have solved something genuinely difficult." That belief shift is a brief. Showcase expertise is a direction that leads to forty-seven bullet points.
What a reference film is for
Reference films are useful and I always ask for them. They tell me faster than any description what register a client is aiming for: spare and direct, or warm and full of people, or fast-cut and urgent.
The thing to do with a reference film is not to describe what you like about it, but to say which specific thirty seconds you would save if you could only keep one. That answer tells me what the client is actually responding to. It is almost never the film's general feel. It is one specific moment: the question a CEO asked mid-sentence that felt unscripted, the cut to a client's face that happened before they had time to compose it, the breathing room at the end before the logo appeared.
I then ask: is there anything in it you would not want in your version? The gap between what they would keep and what they would remove is where the real brief lives.
The sign-off question
One last thing. Before any production, I ask: who has final sign-off on this film, and have they been involved in writing the brief?
The answer is no more often than it should be. The brief is written by a marketing manager, reviewed by a comms director, and the CEO will see the film when it is finished. That is a structure that produces the Friday call. The person who will make the final judgement about whether the film is right had no input into what right means.
Getting that person in front of the brief for twenty minutes before production starts is the cheapest step in the process. It does not have to be a long meeting: a short conversation to confirm the film's purpose, its one key viewer, and what success looks like in practice. If they align with what has already been written, everyone is protected. If they push back, you know early enough that the adjustment costs nothing.
The client from that Friday call and I have made four films together since. The last one she described as exactly right. We got there because we spent the first hour of pre-production answering questions the original brief had left open.
A production team can build almost anything you describe precisely. The brief is not a constraint on what you make. It is the instruction manual for the film that already exists in your head.
