How to make a UGC video ad without a creator

Four prompts you paste into Claude. You describe the ad. Claude builds it.

By Anne Reyes · · 6 min read

A UGC creator costs between three hundred and two thousand dollars per video, and you get one video.

This is the same format, in about forty minutes, with a face your brand owns and can use again tomorrow.

You are not going to learn a video tool. You paste four prompts into Claude, describe the ad you want, and paste your product link. Claude picks the models, pulls your product photos and runs the generations.

What is inside The four prompts, written in plain English with brackets so you fill in your own brand. The two ad formats and when to use each. Whether to give her a script or leave her silent. And the one habit that keeps the cost down: approve a still before you pay for a video.

What you need before you start

  1. An AI model you have already trained, with a name. Not a photo you upload each time. If you do not have one yet, I walk through building her here: how to create an AI model for your brand. Do that first. Everything on this page depends on it.
  2. Claude, with the Higgsfield connector turned on. That is the whole software stack. You will not open a video tool.
  3. Your product page link. Just the URL of the product you are advertising. Claude reads the page and pulls the real product photos off it, so the thing in the ad is your actual product rather than something generated to look like it.

Step 1. Decide the creative direction

This is the only part that is genuinely yours, and it is the part that decides whether the ad is any good.

Everything below is an example. What you ask for depends entirely on the product you are featuring and the direction you want to take. A coffee machine wants a slow morning at home. A set of shoes wants a street and a walk. A serum wants a bathroom and a close-up. Those are different ads and they are not interchangeable.

The two examples on this page are a coffee machine and a set of five shoes, because they need opposite treatments and between them they cover most of what you will make. Read the prompts as shapes to fill in, not as scripts to copy.

Before you write anything, answer four things:

  1. Where is she? A real room or a real street, described physically. Not "somewhere nice."
  2. What is she doing? A verb. Walking, pouring, reaching, sitting down. Not a pose.
  3. What time of day, and where is the light coming from? Hard morning sun through a window is a different ad from flat afternoon light.
  4. What is she wearing? Anything that keeps the product visible, and nothing that competes with it.

Steal the direction from an ad you already like. Find a video or a photo whose mood you want, describe what is in it, and hand that description to Claude.

Step 2. Ask for the opening frame

Do not ask for the video first. Ask for one still, look at it, then have it animated.

Stills cost almost nothing next to video. This is where you find out the outfit is wrong, or the light is flat, or the product is not reading, and it is far cheaper to find out here.

Prompt 1 · the opening frame
Using Higgsfield, generate 4 versions of one still image I can turn into a video ad. Use my AI model [her name]. Use her saved ID. Do not ask me to upload a photo of her. Product: [paste your product page link] Pull the real product photos from that page so the product in the shot is the actual one I sell. The shot I want: - Where she is: [the room or street, described physically. What is underfoot, what is behind her.] - What she is doing: [a verb. Walking across it, pouring it, reaching for it. She is in motion, not posing.] - Light: [hard morning sun from the left, soft overcast, golden hour. Say where the shadow falls.] - What she is wearing: [garment, fabric, color. Keep the product visible.] - The feeling: [calm and unhurried, bright and fast, editorial and still.] Vertical 9:16, highest quality. Show me all four, then tell me which one you would animate and why.

Returns 4 stills · Time about a minute · Cost a fraction of one video

The line worth keeping is "she is in motion, not posing." A catalog stance animates into a person standing still for ten seconds. Give her a verb and the video has somewhere to go.

If the product needs to be exact When your model's face is in the shot, the product comes out close but not pixel-perfect, because the generation is holding her identity as its first priority. If you need the product exactly right, ask Claude for a second shot with no person in it, using prompt 4 at the bottom of this page. Most brands end up posting both.

Step 3. Ask Claude to animate it

Two formats. Pick by how many products are in the ad.

Format A. One product, one calm moment

For a single hero product. She uses it, once, slowly. Ten seconds.

Prompt 2 · the single-product ad
Animate version [number] into a 10 second vertical video ad, 1080p, with sound. Keep the scene exactly as it is in that image. Same face, same outfit, same room, same light. Real-time pacing, nothing sped up. Across the 10 seconds she [three or four small ordinary actions in order. She lifts it, uses it, sets it down, looks toward the window.] Camera: handheld phone, [almost static with a slight natural drift / one slow push toward her]. Sound: [PICK ONE] - No talking. Upbeat music only, bright and easy. - She speaks to camera, calmly, in about 30 words: "[your script]" Tell me the credit cost before you run it.

Format B. Several products, one continuous take

For a collection or a range. The product changes on her as she moves, with no cut. Ten seconds for three products, fifteen for five.

Prompt 3 · the product-swap ad
Animate version [number] into a 10 second vertical video ad, 1080p, with sound. Keep the scene exactly as it is in that image. Same face, same outfit, same setting, same light. She keeps [walking] at a steady unhurried pace for the whole 10 seconds, one continuous take, no cuts. The [product] on her changes [N] times. Each change happens in a single instant, the moment [her forward foot lands / she turns / her hand passes the frame]. Everything else in the frame stays identical. Only the product changes. In this order, about 2 seconds each: 1. [product page link] 2. [product page link] 3. [product page link] 4. [product page link] 5. [product page link] - hold on this one to the end Pull the real product photos from those pages. [If the product changes her posture, say so: her stride and height should adjust naturally as the heel height changes.] Sound: [PICK ONE] - No talking. Upbeat music only, bright and easy. - She speaks to camera, calmly, in about 30 words: "[your script]" Tell me the credit cost before you run it.

Put your best product last. The final two seconds are the only ones a scroller reliably watches to the end, and a sequence that escalates gives them a reason to stay.

The same product, two directions

Both of these are the same coffee machine, the same AI model and the same product link. The only thing that changed between them is the answer to step 1.

Kitchen, morningShe lifts the cup off the brewer and talks to camera. Direct, close, the machine in shot the whole time.
Bedroom, slow startSame machine, softer. Silk, hard morning light, iced instead of hot.

Both were generated in Higgsfield, driven from Claude, from one product page link. Turn the sound on.

Neither one is more correct. The kitchen version sells the machine, the bedroom version sells the morning, and which one you want is a decision about your customer rather than about the tool. That decision is step 1, and it is the only part of this that AI cannot make for you.

Silent, or with a script

Both work. They suit different products, and the prompts above let you ask for either.

Silent with music is the safer of the two and reads closest to a real shoot, because there is no lip sync to get wrong. Use it when the product is beautiful and self-explanatory. Clothes, shoes, homeware, anything where looking at it is the pitch.

A script converts harder when the product actually needs explaining, or when the objection is the thing standing between the viewer and the sale. Use it for anything technical, anything expensive, anything people are skeptical of.

If you write one, the rule is this: concede something before you praise anything. Every cheap UGC ad opens with "I am obsessed with this." Every one that converts opens with a real objection.

"I didn't want another pod machine. My old one made every cup taste the same. This one scans the pod before it brews. You taste it on day one."

Twenty-nine words, and it buys the next ten seconds because it does not sound like an ad. Keep it to about 30 words for a 10 second clip, and read it out loud on a timer before you send it.

Optional. The product-only film Optional

No model at all. Your products arranged on a real surface, one slow camera move. It is the version where the product comes out most accurate, and it makes a good second asset from the same session.

Product onlyFive shoes, real product photos, no model.

Prompt 4 · the product-only film
Using Higgsfield, generate 3 versions of a product photograph with no people in it. Products: [paste all your product page links] Pull the real product photos from those pages and keep every product exactly as it appears, no substitutions. The shot I want: - Arrangement: [standing in a loose row, grouped, laid flat] - Surface: [warm stone paving, pale wood, linen, marble] - Angle: [high angle looking down at about 45 degrees] - Light: [hard low sunlight with crisp cast shadows / soft even daylight] Vertical 9:16, highest quality. Then animate the one I pick into a 15 second vertical video, 1080p, with upbeat music and no talking, using one slow continuous camera move toward the products. The products stay still the whole time. Tell me the credit cost before you run the video.

The prompt chain, in order

#PromptWhat you get
1The opening frameFour stills. You pick one
2Single-product ad10 seconds, one hero product
3Product-swap ad10 to 15 seconds, three to five products
4Product-only filmA second asset, no model needed

Four things that make the difference

Still first, video second. Approve the face, the product and the light on a cheap image. Video is the most expensive thing in the session and the worst place to discover the outfit is wrong.

Ask for the cost before every video. Put "tell me the credit cost before you run it" in the prompt and Claude will stop and check with you. That one line is the difference between three ads and one.

Give every change a trigger. "The shoes change" produces a smear. "The shoes change the moment her forward foot lands" produces a cut you can feel.

Say what must not move. Naming what stays identical, the face, the outfit, the room, the light, is what stops it quietly redecorating between second three and second seven.

The checklist


Can you make a UGC ad without hiring a creator?

Yes. You describe the ad you want in plain English, paste your product page link, and name the AI model you have already trained. Claude handles the tools. The only decision that stays yours is the creative direction: where she is, what she is doing, and what the ad is supposed to feel like.

Should the AI model speak in the ad?

Both work and they suit different products. A silent clip with music is the safest and reads closest to a real shoot, because it removes lip sync entirely and lets the product carry the ad. A script converts harder when the product genuinely needs explaining, and the rule that makes one work is that the first line concedes something about the category before it praises anything. Ask for whichever you want, in the same prompt.

How do you get your actual product into an AI video?

Paste your product page link into the prompt. Claude pulls the real product photos from the page and uses them as references, so the shape, material and hardware come out close to the real thing instead of a generated approximation. You do not need to download or upload anything.

How do you keep the same AI model across every video?

Train the model once, give her a name, and name her in every prompt from then on. Claude looks up the saved version and uses it. That is what makes the second video look like it came from the same brand as the first, and it is the whole reason to train a model rather than generating a new stranger each time.

How long should an AI UGC video ad be?

Ten seconds for a single product, fifteen for a sequence of three to five. Generation tools cap the length, so ask for the length you want and let Claude tell you if it needs adjusting. If you want a shorter cut than the tool allows, generate the longer one and trim the last beat in your editor.

The frames on this page were built with the prompts above, using products from brands I do not work for as worked examples. Nothing here was commissioned. Every prompt is written to be filled in with your own model, your own products and your own creative direction.
