NanoBanana UGC Video Builder (Veo3 + Image Reference, Scene-by-Scene)
Category: AI Video Automation | UGC Production | Content Creation
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
veo3orveo3_fastdepending 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.
