Why we run video and ads under one roof.
The agency makes the film. The media buyer runs the ads. Nobody talks to each other. The video doesn’t fit the channel and the ads can’t find the right creative. Here’s how we do it differently — and why it saves NZ marketing teams real money.
If you’ve ever paid for a brand video and then watched the ads team complain that they don’t have anything in 9:16, you already know the problem. Two specialist teams, two budgets, two timelines. The ads team gets handed a hero film a month after launch and asked to make it work on TikTok.
It usually doesn’t work on TikTok.
The real cost of separating production and media
When the people writing the ad copy are different from the people directing the film, you end up with three predictable problems:
- Wrong creative for the channel. The hero film is 60 seconds, landscape, soundtrack-driven. The ads team needs 6, 15 and 30-second cut-downs in vertical and square, with burned-in subtitles for sound-off viewing. They never got the dailies. They get the locked edit and a clock that’s already ticking.
- No iteration loop. Paid media is creative-led, and creative fatigue is the #1 reason campaigns die. Without an in-house production team, every fresh variant is a new project, a new quote, a new month-long turnaround. Most clients give up and run the same ad until performance collapses.
- Two account managers, two stories. Your video crew thinks they did a great job (they did). Your media buyer thinks the creative didn’t convert (it didn’t, in vertical). Both are right and the budget loses.
What changes when one team does both
We make the video and we run the ads. Same team, same brief, same studio. Three things shift:
1. The film is built for the channel from day one.
Before the cameras turn on, we already know which 6-second hooks, 15-second cut-downs and 30-second versions we need to come out the other side. We block them on the call sheet. The director knows. The talent knows. We shoot for the channel, not just the hero.
2. Creative iteration runs weekly.
New ad variants ship every week, drafted by Claude or ChatGPT, designed in-house, exported in every aspect ratio. We test which hook, which image, which CTA is doing the work — and double down on what works. There’s no “send it back to the agency” loop because we are the agency.
3. Reporting comes back to the same brief.
One weekly summary, one strategist, one set of numbers. The video brief and the ads brief are the same brief. The reporting tells you what video worked, what ad worked and what landing page worked — not a fight between three vendors trying to take credit for the same lead.
“Onepost made the video and ran the ads — which meant nothing got lost in translation. The recruitment campaign hit 22k organic views and our training programs filled up.”

Where this saves real money
The cost difference shows up in three places:
- No double-handling. One brief, one quote, one project manager. You don’t pay an account manager at two agencies to forward emails to each other.
- Faster creative cycles. Variants ship in days, not months. That cuts cost-per-acquisition because you’re not running fatigued creative for weeks while you wait for the next round.
- Better ROAS, measured properly. When the people who made the video are reading the campaign data, the next video gets better. The cycle compounds.
When this approach doesn’t make sense
If you already have a high-performing in-house production team and a separate ads team that talk every week, you’ve solved the problem a different way. You don’t need us. (Hire us for the bits you don’t do internally.)
If your project is genuinely a one-off — a single TVC for a one-time campaign, never to be cut down or re-tested — the under-one-roof advantage is smaller. We can still help, but the savings come mostly from the always-on creative loop, which a one-off doesn’t need.
How to think about it for your team
If you’re currently running paid media and feeling like the creative is the weak link — or making lots of video and feeling like nobody’s seeing it — you’ve got the symptoms of the gap. The fix is to put production and media on the same team, on the same brief, with the same reporting.
