Nano Banana & Veo3 Video Automation

This workflow automates image enhancement and video generation, replacing manual editing and video production. The Multi-Channel Input Trigger Webhook accepts images and prompts, the Input Data Processor Code node validates inputs, the Nano Banana Image Enhancer Code node improves image quality using Google Gemini, the Video Prompt Generator Code node crafts Veo3 prompts via OpenAI, and the Veo3 Video Generator Code node creates 8-second videos. The Initial Processing Wait and Video Status Checker nodes manage video processing, while the Results Formatter Code node compiles results, returned by the Webhook Response node. It benefits small content creators or marketing teams (1-10 staff) producing 50+ videos monthly. The workflow saves 10-15 hours weekly for 50 videos, cutting production costs by 70%. Use cases include social media content, promotional videos, and e-learning. Requires Google Gemini ($0.35/1k tokens), OpenAI ($0.03/1k tokens), and Fal.ai Veo3 ($4-$6/video). Scalable to 200 videos/month. Learning curve costs: $20-$30 for 5-10 videos; mastered cost: $4-$6/video. Install n8n from n8n.io or cloud.n8n.io. Get GOOGLE_GEMINI_API_KEY at cloud.google.com/gemini, OPENAI_API_KEY at platform.openai.com, and FALAI_API_KEY at fal.ai. Set environment variables in n8n: GOOGLE_GEMINI_API_KEY, OPENAI_API_KEY, FALAI_API_KEY. Import JSON, configure Webhook node with POST path 'nano-veo3-generate.' Webhook URL: https://your-n8n-instance/webhook/nano-veo3-generate. Test with Postman: {imageBase64: '...', textPrompt: 'cinematic cityscape', videoIdea: 'urban adventure', geminiApiKey: '...', openaiApiKey: '...', falaiApiKey: '...'}. Check n8n logs for processing status. Common errors: invalid API keys (regenerate credentials), rate limits (wait or upgrade plans), missing image (include imageBase64). Activate workflow in n8n. Monitor dashboard for errors. Optimize by batching requests and reviewing logs weekly.", "businessValue": "Saves 10-15 hours/week automating 50 video productions", "setupTime": "30-45 minutes", "difficulty": "Intermediate", "requirements": [ "Google Gemini ($0.35/1k tokens), OpenAI ($0.03/1k tokens), Fal.ai Veo3 ($4-$6/video)", "API keys for Gemini, OpenAI, Fal.ai (full access)", "n8n instance with environment variables set" ], "useCase": "Automated image enhancement and video generation for content creators"
