Generate cinematic videos from text prompts with GPT-4o, Fal.AI Seedance & Audio

Who’s it for? This workflow is built for: AI storytellers, content creators, YouTubers, and short-form video marketers Anyone looking to transform text prompts into cinematic AI-generated videos fully automatically Educators, trainers, or agencies creating story-based visual content at scale --- What It Does This n8n workflow allows you to automatically turn a simple text prompt into a multi-scene cinematic video, using the powerful Fal.AI Seedance V1.0 model (developed by ByteDance — the creators of TikTok). It combines the creativity of GPT-4o, the motion synthesis of Seedance, and the automation power of n8n to generate AI videos with ambient sound and publish-ready format. --- How It Works Accepts a prompt from Google Sheets (configurable fields like duration, aspect ratio, resolution, scene count) Uses OpenAI GPT-4o to write a vivid cinematic narrative Splits the story into n separate scenes For each scene: GPT generates a structured cinematic description (characters, camera, movement, sound) The Seedance V1.0 model (via Fal.AI API) renders a 5s animated video Optional: Adds ambient audio via Fal’s MM-Audio model Finally: Merges all scene videos using Fal’s FFmpeg API Optionally uploads to YouTube automatically --- Why This Is Special Fal.AI Seedance V1.0 is a highly advanced motion video model developed by ByteDance, capable of generating expressive, stylized 5–6 second cinematic clips from text. This workflow supports full looping, scene count validation, and wait-polling for long render jobs. The entire story, breakdown, and scene design are AI-generated — no manual effort needed. Output is export-ready: MP4 with sound, ideal for YouTube Shorts, Reels, or TikTok. --- Requirements n8n (Self-hosted recommended) API Keys: Fal.AI (https://fal.ai) OpenAI (GPT-4o or 3.5) Google Sheets Example Google Sheet --- How to Set It Up Clone the template into your n8n instance Configure credentials: Fal.AI Header Token OpenAI API Key Google Sheets OAuth2 (Optional) YouTube API OAuth Prepare a Google Sheet with these columns: story (short prompt) numberofscene duration (per clip) aspect_ratio, resolution, model Run manually or trigger on Sheet update. --- How to Customize Modify the storytelling tone in GPT prompts (e.g., switch to fantasy, horror, sci-fi) Change Seedance model params like style or seed Add subtitles or branding overlays to final video Integrate LINE, Notion, or Telegram for auto-sharing --- Example Output Prompt: “A rabbit flies to the moon on a dragonfly and eats watermelon together” → Result: 3 scenes, each 5s, cinematic camera pans, soft ambient audio, auto-uploaded to YouTube Result
