A 30-second ad storyboards into 8 to 12 shots across four beats: hook (0-3s), problem or context (3-10s), product in use (10-22s), and resolution with the call to action (22-30s). Write the beats first, assign shots to beats second, and generate frames only once the beat structure survives being read aloud against a timer. Storyboarding shot-first is how ads end up with a beautiful opening and no room for the product.
Setup
You need the creative brief (specifically the single message), the approved moodboard or style frame, and a timer. The timer is not a joke: read your beat structure aloud at the intended pace before drawing anything, because 30 seconds is much shorter than it reads on paper.
The structure
| Beat | Time | Shots | Job |
|---|---|---|---|
| Hook | 0-3s | 1-2 | Stop the scroll. Motion or a face, in the first 8 frames |
| Context | 3-10s | 2-3 | Establish the problem or the world |
| Product | 10-22s | 3-5 | The mechanism. This is the ad |
| Resolution | 22-30s | 2 | Outcome plus the call to action, brand visible |
Two structural rules that hold across formats. The product should appear before the halfway mark, because viewers who leave at 15 seconds should still have seen it. And the last shot should hold the brand for at least a second and a half, since anything shorter does not register on a muted feed scroll.
Step by step
1. Write the beats as sentences. Four sentences, one per beat. If you cannot write them, the brief is not settled and storyboarding will not settle it.
2. Assign shot counts to beats. Product gets the most shots. Hook gets one, occasionally two. A beat with more than five shots is a beat that needs to be two beats or fewer ideas.
3. Specify each shot as a row. Framing, subject, camera move, duration, and a note tying it to the moodboard. This is a shot list, and building it before the frames keeps you honest about the total runtime.
4. Generate the frames. One still per row, in the approved look, conditioned on the moodboard references so the frames match each other. Stills first, motion second: a still costs 6 to 21 credits, a video clip costs 54 to 448, so resolving composition on stills is roughly ten times cheaper than resolving it in motion.
5. Time the board. Lay the frames in sequence with their durations and check the sum. Overrun of 3 to 5 seconds at this stage is healthy, because the edit will want trim room. Overrun of 12 seconds means cutting a beat, not trimming shots.
6. Animate only what needs motion to be judged. Usually the hook and one product shot. The rest can stay stills through client approval.
The cost math, with canon prices
For a 10-shot board using 8frame credit prices (a credit is $0.01 at pack rate):
- 10 still frames on Seedream 5 at 6 credits each: 60 credits, about $0.60
- Same 10 on Nano Banana Pro at 21 each, when the frames go in front of a client: 210 credits, about $2.10
- Animating 2 key shots on Veo 3.1 Lite (8s with audio, 54 each): 108 credits
- Animating those 2 on Kling v3 Standard (5s with audio, 86 each): 172 credits
A full storyboard with two animated shots lands between 170 and 400 credits, comfortably inside a $19 Starter month's 1,000 credits, with room to iterate the hook five times. Delivering the finished ad on premium models is the separate, larger number: Veo 3.1 Standard is 448 credits for 8 seconds with audio, so reserve it for the shots that carry the ad.
When to use this vs skipping the board
Skip the storyboard for single-shot social posts and organic content where the format is the message. Build it whenever there is a client, a media budget, or more than three shots, because the board is where disagreements cost minutes instead of generations.
FAQ
How many shots should a 30-second ad have? 8 to 12 for most formats. Fewer than 8 and the pacing tends to drag; more than 12 in 30 seconds means average shot lengths under 2.5 seconds, which works for a fast-cut style and fights you everywhere else.
Do I need a storyboard if the ad is AI-generated? More than before, not less. Generation makes producing shots cheap, which makes producing the wrong shots cheap too. The board is what keeps a low unit cost from turning into high total spend.
Stills or animatics for client approval? Stills plus two animated key shots. A full animatic is worth it when timing is the thing in dispute.
The board is easiest to keep honest when the frames, the durations, and the generations live on one surface. The 8frame canvas is free and unlimited, and generation is paid from $19/month.
