Ad Multiplier: turn one winning ad into a lineup of fresh variants

Every ad wears out. The same face in the same kitchen, shown to the same people, slows down even when the idea behind it is still great. The usual fix is a reshoot. The Ad Multiplier is the faster one.

What it does

Give it a video ad that is working and ask for variants, up to twelve at a time. Each one gets a new person, a new outfit, a new location or new props, while the things that made the original work stay exactly the same: the cut, the camera motion, the pacing and the original audio. Any burned-in captions are removed, so each variant starts clean.

You choose what changes. Vary all four, or only the location, or only the outfit. Add notes the variants must respect, like keep it women 25 to 40 or no gyms.

Why the variants hold up

The Multiplier does not ask a model to imagine your ad all over again. It uses the original video itself to drive every variant. Hermoso restyles one opening frame with the new person, outfit and set, and the original's motion carries that frame through the whole ad.

So each variant comes back:

• The same length as the source, cut for cut.
• With the same performance: the same gestures, the same timing, the same beats.
• With the original audio, so the voice and the music that sold the first version sell the next one.

What works best

Ads with a person clearly on camera, upper body in view, are the sweet spot, which covers most UGC, testimonial and talking-to-camera spots. Sources can run up to 30 seconds. If a video does not suit that approach, Hermoso switches to a second method and tells you it did.

Ideas for what to vary

• Location, for the season. The same ad in a sunny backyard for summer and a cosy living room for winter.
• The person, for the audience. Different ages, styles and looks, so more people see someone like them.
• Outfit and props, for the product line. Swap what is on the table or in their hands to match each version of the product.
• Markets. Name the regions you sell in and the variants restyle for each one.

Testing variants without guesswork

Because every variant keeps the same script, timing and audio, the only thing different between them is what you chose to change. That makes the test clean: if the backyard version beats the kitchen version, you know it was the setting. Run a batch, keep the two best, and multiply again from there.

Where to find a winner to multiply

• A render in your Library that did well.
• Your top post from post_performance, or your best ad in meta_insights.
• Any finished video you have a link to.

How to use it

In the Studio: make six variants of this ad with different people and locations. From Claude, ChatGPT or Cursor: multiply_ad with the source video, a count, and optionally which axes to vary. It runs in the background, and get_job hands back each finished variant.

Then put them to work. Schedule them across your channels, or run them side by side in the same ad set and let the numbers pick the next winner. When one pulls ahead, multiply that one.

Questions people ask

What does the Ad Multiplier change?

The person, outfit, location and props, in any combination you choose. The cut, camera motion, pacing and original audio stay the same, and burned-in captions are removed.

How many variants can I make at once?

Up to 12 per request, and six by default.

How long can the source ad be?

Up to 30 seconds. Every variant comes back the same length as the source.

Does it keep the original voiceover and music?

Yes. Each variant keeps the source's original audio.

Can an AI agent run it?

Yes. Call multiply_ad with the source video URL and a count, then collect the variants from get_job.

Can I choose what changes and what stays?

Yes. Pick any mix of character, outfit, location and objects to vary, and add notes the variants must respect, such as an age range or places to avoid. Everything you do not pick stays as it was in the original.
