How to Make UGC Video Ads with AI: A Complete Workflow

Why UGC-style ads, and what makes them work

UGC (user-generated content) ads look like a real person filmed them on a phone: a creator talking to camera, showing the product in their hands, reacting to it in their own kitchen or bedroom. They work because they feel like a recommendation instead of a commercial. That feeling comes from a few specific craft choices: handheld framing, natural light, casual speech, real product handling and a strong first two seconds.

With AI, the challenge is not producing footage. It is producing footage that keeps your product accurate, keeps the creator consistent and comes out in enough variations to test. The workflow below is built around those three problems.

Step 1: Start with the product in Biggs Ads

Open Biggs Ads (/studio/marketing) and upload your product to the product library. You only do this once. After that, you can place the same product in any scene, which is what keeps the bottle, box or device looking like your actual item across every ad you make.

A brand kit is the second layer. Biggs Ads can store your logo, colors, fonts, tone and target audience and apply them automatically to everything it generates. You can begin with just the product and add the brand kit when you are ready, but if you plan to produce ads regularly, setting it up early saves you from repeating brand instructions in every prompt.

From there, Biggs Ads generates product shots, lifestyle photos, banners and video ads. Its formats include feed, story, banner, UGC and video ad variants, produced in one go, so a single brief can cover several placements at once.

Step 2: The fastest route with URL to Ad

If you want a first draft in minutes, use the URL to Ad app. Paste a product page link and the AI studies the product, writes a script and produces a video ad with voiceover. Treat the result as a baseline: it shows you how the product reads on screen and gives you a script you can rewrite with sharper hooks.

A practical approach is to run URL to Ad first, note which product benefits it pulls out, then use those benefits as raw material for the hooks and scripts in the next steps.

Step 3: Write hooks before you write anything else

In UGC ads, the opening line does most of the work. Write five to ten hooks before you generate a single clip. Good hook patterns include the confession ("I was wrong about this"), the specific problem ("If your coffee goes cold before you finish it"), the unexpected result ("This cost me less than lunch") and the direct challenge ("Stop buying cheap earbuds").

Keep hooks short enough to say in two or three seconds, and make sure the first frame matches the line: if the hook is about a messy desk, open on the messy desk. Once you have candidates, the Virality Predictor app scores your hook, title and cover, then writes better ones. Use it as an editor, not a final judge.

Step 4: Cast a consistent creator

A UGC campaign works best when the same face appears across variations, the way a real creator would. Biggsfluencer lets you design a character, then automatically shoots five reference angles (both sides, profile, a laughing close-up and full body) that attach to everything you make. You can give them a persona, a bio, a tone and an ElevenLabs voice in 29 languages, and train a private LoRA in one click for maximum consistency.

Aim for believable rather than glossy. Biggsfluencer supports quirky looks as well as polished ones, and slightly imperfect creators often read as more authentic in a UGC context.

Step 5: Generate talking clips with Seedance 2.5

Seedance 2.5 is the flagship video model in Biggsfield: up to 30 seconds, native audio with lip-synced speech, and multiple reference images. For UGC, that means you can attach your creator and your product as references and write a short multi-shot ad in one prompt.

Prompting rules from the model guide: put spoken lines in double quotes with who says them and how, write shots in order as "Shot 1: … Shot 2: …" each with its own camera, and refer to reference images as @Image1, @Image2. Pricing examples: 5 seconds at 480p with sound costs 184 credits (about $1.77 on Creator), 8 seconds at 480p costs 294 credits, 5 seconds at 720p costs 395 credits and 5 seconds at 1080p costs 970 credits. Draft at 480p, then re-render the winners at higher resolution.

Shot 1: Handheld selfie-style medium close-up, slight camera shake. @Image1, a woman in her late 20s in a sunlit kitchen, holds @Image2, a matte green water bottle, up to the lens and says, excited and a little breathless: "Okay, I did not expect a water bottle to fix my afternoon slump." Shot 2: Close-up, camera tilts down as she twists the lid open with one hand; soft click, quiet kitchen ambience. Shot 3: Medium shot, she takes a sip, grins at the camera and says casually: "Link's below. Thank me later."

Step 6: Get great value with Kling 3.0 Pro

Kling 3.0 Pro is a 1080p version of Kling 3 with multi-shot and native audio, described in Biggsfield as great value. Prices: 5 seconds with sound for 140 credits (about $1.35 on Creator), 8 seconds for 224, 10 seconds for 280 and 15 seconds for 420.

Kling responds to physical, concrete action and strong camera language. Its native voice speaks only English or Chinese, so write dialogue in English. For multi-shot, give each shot a self-contained prompt with subject, action and camera, plus a duration; the durations add up to the total.

If you are unsure which model suits a product, the AI Video studio lets you run one idea on up to four models at once and keep the best take.

Shot 1 (4s): A young man in a gray hoodie sits on a bedroom floor holding an open case of white wireless earbuds toward a handheld phone camera, soft window light, slight shake. He says, matter-of-fact: "These cost less than my last pair and they sound better." Shot 2 (4s): Extreme close-up of his fingers lifting one earbud from the case and pressing it into his ear, camera pushes in slowly. Shot 3 (2s): Medium shot at chest height, he closes his eyes and nods to the music with a small smile, static camera.

Step 7: Add unboxing and B-roll

Talking clips need cutaways. The Unboxing Video app produces hands unboxing your product on camera, ASMR style, which is one of the most familiar UGC formats and makes a natural middle section between the hook and the call to action.

Other useful product apps include 360° Product Video for a cinematic spin, Product Photo for turning a casual snap into a commercial shot, and Splash Packshot for a slow-motion splash of water, juice or paint. Mix one or two of these into a creator-led ad rather than letting them dominate; too much polish undercuts the UGC feel.

Step 8: Multiply concepts and test

One ad is a guess. Ad Multiplier takes one product and writes distinct concepts, each with its own hook, audience and setting, then renders them all so you can A/B test. Pair it with the hooks you wrote in Step 3: let Ad Multiplier explore angles you would not have considered, and keep your strongest manual hooks in the mix.

Test one variable at a time where you can. If two ads differ in hook, creator and setting all at once, a winner tells you little about why it won.

Step 9: Edit, caption and deliver every aspect ratio

Bring your clips into Biggs Cut, the timeline editor next to your generations. It has multi-track layers for video, music, voice and text, word-timed auto subtitles in the style you choose, and cloud rendering that continues after you close the tab.

Captions matter for UGC because many people watch with sound off. Burn them in, keep them large and place them away from platform interface elements. Biggs Cut exports 9:16, 1:1 and 16:9 from the same project: use 9:16 for stories, reels and short-form feeds, 1:1 for square feed placements, and 16:9 for landscape video placements. Check each crop so the product and the creator's face stay in frame.

The full workflow at a glance

1. Upload the product in Biggs Ads, and add a brand kit when you are ready. 2. Run URL to Ad for a fast baseline script. 3. Write hooks and refine them with Virality Predictor. 4. Create a consistent creator in Biggsfluencer. 5. Generate talking clips with Seedance 2.5 or Kling 3.0 Pro, comparing models where useful. 6. Add Unboxing Video and product B-roll. 7.

If you produce ads every week, Biggs Agent can plan shots, pick models, generate and edit while you approve, and run scheduled tasks such as "Every Monday, three new product ads." Whatever you automate, review every ad before it goes live and follow each ad platform's rules on disclosing AI-generated content.
