1. Why AI UGC Ads Matter
UGC ads stand out in crowded feeds because they look natural and unpolished, unlike high-production content. Brands pay $100-$500 per video, and AI can now replicate this authentic look in minutes without human filming.
2. Step 1: Create Your AI Influencer
Use image generation models (GPT Image 2 or Nano Banana Pro) with a structured JSON-style prompt. Define gender, age, ethnicity, background, style, camera placement, body coverage, aspect ratio (9:16 for social), and additional details to generate realistic influencer images.
3. Step 2: Place Your Product
Upload high-resolution, well-lit product images alongside influencer photos. Use AI to combine them by requesting the influencer hold or showcase the product. Generate multiple variations for different angles and scenarios.
4. Step 3: Create the Video Ad
Use Seedance 2.0 to generate video from the influencer-product image. Prompt with accent, vibe/mood, camera motion, eye direction, and a structured list of dialogues paired with specific actions. The model executes all parameters precisely.
5. Prompting Best Practices
JSON-style structured prompting yields better results than conversational prompts. Organize parameters as key-value pairs, and for dialogue-action sequences, list each line with its corresponding action to guide the AI's video generation.
6. Advanced Techniques
Generate multiple B-roll shots while the avatar speaks and stitch them together for dynamic, edited UGC content. Iterate on prompts to refine outputs and create multiple starting points for different video variations.
