NanoBanana UGC Video Builder (Veo3 + Image Reference, Scene-by-Scene)

Transform how you create short-form videos forever. The NanoBanana UGC Video Builder is a fully automated n8n workflow that turns your text prompts into high-quality, scene-by-scene UGC videos — powered by GPT + Veo3 (KIE.ai).

This automation doesn’t just generate videos. It builds an entire creative pipeline that mimics how real content creators film product ads and story-driven social clips.

Here’s how it works:

Script Generation: GPT creates structured UGC-style scripts broken into natural, conversational scenes.

Prompt-to-Video Conversion: Each scene is automatically transformed into Veo prompts, using veo3 or veo3_fast depending on render speed preferences.

Optional Image Guidance: You can upload a reference image (e.g., your product or brand asset) to make the scenes visually consistent.

Render & Poll: The system sends all prompts to Veo for generation, waits for each render to complete, and polls task statuses for real-time updates.

Final Merge: Once all scenes are ready, the automation combines them into a single seamless video file — complete with captions or sound options if enabled.

The result? You get authentic, high-performing user-generated content ready for TikTok, Instagram, and paid ad campaigns — all without hiring actors, editors, or videographers.
