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 1. Accepts a prompt from Google Sheets (configurable fields like duration, aspect ratio, resolution, scene count) 2. Uses OpenAI GPT-4o to write a vivid cinematic narrative 3. Splits the story into n separate scenes 4. 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 5. 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 ( - OpenAI (GPT-4o or 3.5) - Google Sheets Example Google Sheet --- How to Set It Up 1. Clone the template into your n8n instance 2. Configure credentials: - Fal.AI Header Token - OpenAI API Key - Google Sheets OAuth2 - (Optional) YouTube API OAuth 3. Prepare a Google Sheet with these columns: - story (short prompt) - numberofscene - duration (per clip) - aspectratio, resolution, model 4. 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
