AI Video Ads Generator: Test 12 Concepts, Then Animate the Winner
SynthPulse doesn't have one button that outputs a finished video ad — it has two features that do the job better used together: a batch tool that produces 12 finished ad stills for 240 credits, and image-to-video models that animate whichever one wins. The real cost of both steps, and the workflow that connects them.

There is no single button in SynthPulse labelled "make an ad video." What there is instead is two features that solve the two real problems in making one, used in sequence: a batch tool that turns one product photo into 12 finished ad concepts for less than a single stock video license, and an image-to-video model that animates whichever concept actually tests well.
Most of the cost in a real ad campaign isn't the final video — it's finding out which concept works before you spend the render budget on it. That's the order this workflow is built around.
Step one: 12 finished ad stills, one variable changed at a time
The Image studio's batch mode has a template built for exactly this — the ad creative test matrix. Feed it one product photo and it produces a set of finished paid-social ads, not clean product shots waiting for someone else to add copy: the wordmark, a headline hook, a supporting line, and a call-to-action button are baked into every image, at whichever aspect ratio you set for the run — square by default, or switch to a tall portrait frame before you start if that's the placement you're testing.
The point of a test matrix is that only one thing changes per item, so you can actually tell what moved the number: the background environment, the camera angle, product-alone versus product-in-use, or the headline hook itself. Product, palette, lighting and button wording stay identical across the set — otherwise a winning concept doesn't tell you why it won.
Default batch size is 12 concepts. The scenario doesn't lock you to one model, but Nano Banana 2 is what the picker opens with by default, at 20 credits a render — that's 240 credits for the twelve renders at the default, less than the 280-credit floor of animating a single shot on Seedance 2.5, the platform's most expensive video model. (The batch composer also charges a small one-time credit for drafting the twelve prompts from your goal text — shown on the button before you confirm, and skipped entirely if you re-run a draft you already paid for.) Testing is supposed to be the cheap part.
Step two: animate only the concept that wins
Once one still wins — more clicks, better hook, whatever your test is actually measuring — that's the one shot worth paying to animate. This is a job for one model at a time, not a batch: ten models in the Video studio take a still and add motion, and which one to reach for depends entirely on how much the shot needs to move.
- A slow push, a label reveal, product sitting mostly still → Seedance 1.5 Pro, 18 credits at 480p to check the motion works, 35 at 720p for the real deliverable.
- A full turntable, a liquid pour, anything with real physical motion → Kling 3.0, 140 at 720p, 180 at 1080p — the tier built to hold motion that a cheaper model blurs or drops frames on.
Test cheap, animate once. A 12-concept test (240 credits) plus a 720p animation of the winner on Seedance 1.5 Pro, the cheapest option (35 credits), runs about 275 credits for the renders themselves — call it 276 once you add the small one-time copywriting charge from step one. Swap in Seedance 2.5 at 720p for motion Kling 3.0 still can't hold (630 credits), and the same funnel runs closer to 871 — still worth knowing before you commit, not after.
What this workflow does not do
It does not stitch multiple animated shots into one longer cut — there's no assembly step here, and the Short Film workflow is built around a different job (turning a song into a synchronized video), not general-purpose product-ad editing. If a campaign needs a 15-second multi-shot sequence, that's multiple single-shot exports assembled outside the platform, the same way you'd cut together any set of clips.
The Video studio does have its own batch scenario for testing paid-social video variants directly, also defaulting to 12 — it's the right tool when what you're testing is the motion itself: an opening camera move or a beat that doesn't exist in a still. But it bills at full per-video pricing on every variant, not per-image: 12 variants at even the cheapest video model's base rate runs at least 420 credits, 1.75× the 240-credit still batch above. That's why this workflow tests on stills first whenever the concept can be judged from a still — save the video batch for testing motion specifically, not for testing a headline or a background a still already settles.
Prompts that keep the product on-brand through both steps
The failure mode in both steps is the same: the model redraws something that was supposed to stay fixed. Two patterns that hold:
For the still (batch template):
Same product, same label, same bottle colour and cap across every item. Change only the background: [environment 1], [environment 2], [environment 3]. Headline text exactly as written: "[your hook]". Do not alter the logo, the product proportions, or the button wording.
For the animation (image-to-video):
Animate this exactly as composed — do not change the product's position, the label, or the background. [Specific motion]: a slow push toward the label, or a 15-degree turntable rotation, or condensation beading and running down the bottle. Nothing else in the frame moves.
Locking what must not move is worth more prompt real estate than describing what should — the model can already see the still; it needs the motion instruction, not a re-description of the product.
When this is the wrong tool
If the ad needs a real person — a spokesperson, a testimonial, someone actually holding or using the product on camera — this workflow is the wrong starting point. It's built around product photography that a model extends into motion, not talent direction.
And if you already know which single concept you want with no testing step, skip the batch entirely and go straight to animating one still — paying for 12 concepts to test a decision you've already made is the same mistake as skipping the test matrix and hoping the first video you render happens to be the one that converts.
