AI Ad Generator
Nobody funds an ad they cannot picture. Board the idea on Wan 3.0 first — the beats moving, in the right ratio, with sound — and take that into the meeting instead of frames that sit still. Your first clip is free.
Four commercial cases from Wan's own published creator handbook, each printed with the complete prompt that produced it. Two of them carry Wan's watermark, which is left on: they are Alibaba's runs, not ours. Collected under CC BY 4.0 — see the note below.
THE BRIEF WAS A DOCUMENT · 16:9 · 30SA brand film asked for as a proposal, not as a shot list. The prompt names the story, the rule (bare-faced throughout, no voiceover, no efficacy claims) and the end card, and lets the model board the rest.
What an AI ad generator
is on this site
It is a place to make the idea watchable before anyone commits a budget to it. You write a beat, the model returns it moving and with sound, and you keep the ones that survive being seen.
One beat at a time
Picture, motion and sound generated in the same pass
Most products ranking for this phrase are performance-marketing tools. They plug into an ad account, spin forty variants off one asset, score them against spend and push the winners live. That is a real job and this site does none of it — there is no ad-account integration here, no avatar library, no variant scoring and no media buying. The job upstream of all that is the one nobody automated. Before there is spend to optimise, somebody has to get the idea approved, and what decides that room is whether the people in it can see the thing. Boarding a spot for that meeting is a real line item and a two-to-three week wait, and what it buys is frames that do not move. Four beats here is a few hundred credits and an afternoon. The four films above are Wan's own published handbook cases, not ours, collected under CC BY 4.0. The watermark on two of them is theirs and stays on — a mark stripped off somebody else's work is the one thing an attribution licence actually forbids. It is also why each one can be printed with its prompt verbatim rather than paraphrased — including the twenty-two-second dashboard, whose prompt runs to two and a half thousand characters, because that length is the thing being demonstrated.

- No ad-account connection, no pixel, no audience targeting and no media buying.
- No variant engine — there is no button that returns forty cuts scored against spend.
- No avatar or stock-presenter library; a person in your film comes from your own reference or from the prompt.
- No brand-safety review. A generated spot still goes through whatever approval your client already has.
Hand over the proposal, or write the beats yourself
The two published cases below were briefed in opposite directions, and both worked. Which one you want depends on whether the idea is already decided.
- proposal · 30s
Hand over the proposalDocument or linkThe bare-faced skincare film was asked for as a story and a set of rules — no voiceover, no efficacy claims, product shot at the end — and the model boarded the thirty seconds. Use this when the argument is settled and the shots are not. 
storyboard · 9sWrite the beatsTimecoded shot listThe paper-craft launch names five frames and the second each one owns. Use this when the client has already approved a board, or when a specific thing has to be on screen at a specific moment.
Hand over the proposal when you are pitching a feeling and the room will argue about shots later. Write the beats when the board is signed off and the job is to make it move. The expensive mistake is doing the second while the first is still unresolved — you pay per second either way, and re-boarding a spot nobody agreed on is where the credits go.
Five ways a generated ad stops being usable
None of these are aesthetic. Each one is a reason the film cannot go in front of the client, which makes it a reason the credits were wasted.
The pack changes between shots
Every generated second is a fresh sample. Nothing carries a label, a logo lockup or a bottle silhouette forward unless the prompt makes it carry.
Supply the pack shot as a reference image and name it in the prompt, then add the appearance lock so the wording travels with every beat. The snack case in the handbook does exactly this and states the constraint outright: the gold-stamped logo and colour scheme stay consistent without distortion.
Reference + lockThe text on the pack is unreadable
Small type is where generative video is weakest, and a pack shot is mostly small type.
Shoot the legible frames as close-ups and say what has to be readable. Anything below about a headline size, treat as decoration and plan a graphic over it in the edit.
Shot choiceThe voiceover lands on the wrong beat
Sound is generated with the picture, so timing is a prompt decision, not an edit decision.
Specify the read speed and quote the line. The dashboard case asks for about 2.5 words a second and names where the music sits under the voice, which is why the numbers and the read stay together.
Prompt structureIt is 30 seconds and the spot is 60
Thirty seconds is the ceiling for one clip on this model.
Board it as beats and cut them together. Every case here is a single generation; a longer spot is several, and holding the pack and the grade steady across them is the work.
Hard limitLegal will not clear it
A concept film made to win a meeting often contains claims, comparisons or a likeness that nobody has approved.
Keep claims out of the picture at concept stage — the skincare case runs zero efficacy claims and zero voiceover on purpose, and is stronger for it. Add the legal line when the idea is bought.
Brief discipline
A run that fails outright is refunded automatically. A run that succeeds and is simply wrong is not, which is the whole argument for boarding at 480P before you commit to 1080P.
What boarding a spot actually costs here
Billing is per output second, so length and resolution are the only two dials that move the number. A 30-second concept film — the longest single clip this model makes — is 240 credits at 480P, 480 at 720P and 960 at 1080P. The four beats of a conventional spot at 5 seconds each are 640 credits at 1080P. The smallest pack is $9.90 for 360 credits, which is 22 seconds of 720P; Pro is $39.90 a month for 2,240 credits, which is roughly four and a half 30-second films at 720P every month.

Board the whole thing at 480P first. It costs a quarter of the 1080P run, it is the same model and the same cut, and it answers the only question that matters at concept stage — does the idea survive being watched.

How to board an ad concept
before the budget exists
Five steps, and the first two happen before you spend anything.
Write the beats as a list, not as a paragraph
One line each: what is on screen, what is said, how long it holds. If you cannot write the beat, the model cannot shoot it — and finding that out in a text editor is free.
Do this firstDecide which beats need a reference
Anything carrying a pack, a logo or a person needs an image supplied and named in the prompt. Anything else can be described.
Before generatingRun the whole thing at 480P
A quarter of the price of 1080P on the same model. You are looking for whether the idea reads, not whether the grade is right.
First passCut it and watch it cold
Beats that were fine in isolation fall apart in sequence. This is the pass that finds the one that has to be rewritten.
The honest passRe-run only the beats that survived, at 1080P
Not the whole film. The point of boarding cheaply is that you only pay full price for the shots that made it into the pitch.
Before the meeting
The order matters more than it looks. Every step above exists to move a decision earlier, where changing your mind is free.
AI ad generator questions
What it will not do, what a spot costs, and who owns the result.
Will it generate forty ad variants and push them to Meta?
How long can a single ad be?
What does a 30-second concept film cost?
Is there a free way to test it?
Does it do voiceover and music, or is that a separate step?
Will my product survive the shot without changing?
Can I use the output in a real campaign?
Can I hand it a deck instead of writing prompts?
Is the free 480P clip the same model as the paid one?
What happens if a generation fails?
Board the hardest beat first. It is free.
Take the shot you are least sure the room will believe, and generate it before you write the deck around it. If it does not survive three seconds at 480P, it will not survive the meeting.
