UGC Ad Production Pipeline

Required Inputs (ask the user for ALL of these before starting)

Before generating anything, collect:

• Product — what is being advertised (name, URL, or image)
• Reference UGC video — a real UGC video in the same niche/style (Pinterest, TikTok, YouTube link). Used for script style, creator personality, and shot reference.
• Creator face references — 2+ images of real people (attractive, matching the brand vibe). These get face-mixed in Nano Banana Pro to create a new, non-existent creator.
• Target audience — who the ad is for (e.g. women 18-35 with acne-prone skin)
• Hook type — problem/solution, before/after, testimonial, transformation, or let the agent decide based on the product
• NEVER ask
• Which editing tool to use (always Canva)
• Video length (always 15 seconds)
• Aspect ratio (always 9:16 vertical)
• Which video model (always Kling 3.0)
• Which image model (always Nano Banana Pro)
• Step 1 — Script Writing (Claude 4.6)
• Tool: Claude claude-sonnet-4-6 (strong reasoning + creative writing — feed it as much context as possible)

Prompt template:

Make a UGC script for a 15-second video like [REFERENCE VIDEO] but for [PRODUCT]. Use [CREATOR DESCRIPTION from face references] as the UGC creator/speaker. Include:

• Hook (first 3-5 seconds): show the problem visually + audio hook
• Voiceover lines with exact words
• Cut descriptions: what the camera shows at each moment (creator face, product, before/after, etc.)
• Actions and mannerisms: make the creator feel like a real character — nervous laugh, hair tuck, direct eye contact, pointing at product, etc.
• Call to action (last 2-3 seconds)
• Timestamps for each cut/action Output as a shooting script with columns: Timestamp | Voiceover | Visual/Shot | Action/Mannerism Notes:

Give Claude maximum context: the reference video URL, product details, target audience pain points, other viral UGC videos in the niche, storytelling frameworks (problem-agitate-solve, before/after, etc.) The more context, the better the script. Claude's reasoning capability is the advantage here. Virality principles to bake in: pattern interrupt hook, social proof, transformation moment, urgency CTA Output: A timestamped shooting script with voiceover, visuals, and creator mannerisms.

Step 2 — Generate the Creator Face (Nano Banana Pro) Tool: Nano Banana Pro (4K — required for realistic skin texture, pores, detail)

Prompt template:

Mix these two faces to create a new attractive face that does not belong to any real person. Use the result as the face of a UGC beauty/lifestyle content creator. Generate at 4K resolution. Hyperrealistic skin texture, natural lighting, creator holding a ring-light mic. Notes:

• Use 2+ Pinterest/stock face references that match the brand personality (relatable, aspirational, niche-appropriate)
• Generate with product in hand or near face for the first-frame reference
• You want skin pores, micro-detail, natural imperfections — this is what makes it not look AI
• Platform options (cheapest to best):
• Higgsfield (creator plan) — freemium, works
• Fal.ai — use coupon pixelriot20hackathon-fal for $20 free credits
• Google AI Studio — paid, most control
• Generate 3-5 variants, pick the most realistic one
• Output: A 4K portrait image of the AI creator holding the product.

Step 3 — Generate the Video (Kling 3.0) Tool: Kling 3.0 (15-second multi-shot model)

Why Kling 3.0:

15-second native output length

Multi-shot: can cut between creator speaking → product closeup → skin transformation → back to creator Expressive: understands creator mannerisms, gestures, personality Has contextual understanding of content platforms (UGC native) Setup:

Input: creator image (Step 2) as the start frame

Input: product image as a reference image (not necessarily start frame — can be mid-video reference) Input: shooting script (Step 1) as the motion/shot prompt Prompt structure:

[First frame: creator holding product, looking at camera, natural lighting] Cut 1 (0-3s): Creator speaks directly to camera with [mannerism], says "[hook line]" Cut 2 (3-7s): Close-up of product being applied / used on skin Cut 3 (7-12s): Creator reaction shot — [emotion/mannerism from script] Cut 4 (12-15s): Creator faces camera, delivers CTA, [mannerism] Notes:

• Control shots = telling Kling exactly what each cut shows. This is not just prompting — it's directing.
• Multi-shot = you describe the cuts like a director, not a prompter
• If confused: watch a Kling 3.0 multi-shot tutorial before attempting
• Cost: ~$4-5 per 15s clip. Free testing: Fal.ai with coupon pixelriot20hackathon-fal
• Platforms: Higgsfield, official Kling AI website, Fal.ai
• Output: A 15-second raw video clip.

Virality Principles (Bake Into Every Step)

Hook = Problem Mirror: Show the audience their own problem in the first 3 seconds. They stop scrolling because they see themselves. Before/After = Hope Loop: After the problem hook, show the transformation. This creates desire. Audio Hook: The whoosh SFX at the cut is a pattern interrupt — keeps watch time up. Creator Mannerisms = Trust: A creator that feels like a real person (laughs nervously, tucks hair, sighs) builds subconscious trust faster than a perfect delivery. Reverb = Room Presence: 10% reverb makes the voice feel like it was recorded in a real space, not a studio. Removes the "AI radio voice" feel. CTA Urgency: Last 2-3 seconds. Direct, specific, low-friction ("link in bio", "tap the link", "DM me").

Branding Note

If this is for a real account/brand (not testing):

• The creator face should match the brand's target audience persona
• The creator's style/vibe should be consistent across all UGC videos
