Generate Cheap Viral AI Videos for TikTok with Veo3 & Postiz

This n8n workflow fully automates the production and publishing of short, viral AI-generated videos for TikTok. Triggered from a central Google Sheet, it pulls video prompts and durations, generates videos cheaply with Google Veo3 Fast via the Fal.ai API, polls for completion, downloads the output, and uploads it to Google Drive for storage. It then enhances the video with SEO-optimized titles using GPT-4o before seamlessly posting to TikTok through the Postiz integration, requiring no manual intervention.

Key benefits include cost-effective video generation compared to traditional tools, full end-to-end automation from prompt to publish, centralized management via spreadsheets for non-technical users, and boosted engagement through AI-generated SEO titles. It's ideal for scheduled batch operations, saving hours of manual content creation and uploading time.

The workflow supports self-hosted n8n with community nodes and works via simple steps: sheet-based triggering, API-driven video gen with status polling, Drive storage, title optimization, and hands-free TikTok posting. Use cases span social media marketers, content creators, and agencies aiming for viral TikTok campaigns without coding or expensive tools.
