This workflow uses OpenAI to plan production, Kie to generate audio and artwork, and BeatAPI to render the final video.\n\n### How it works\n1. The n8n form captures the theme, genre, mood, visual style, audience, duration, language, aspect ratio, resolution, and quality.\n2. OpenAI returns structured music, image, and video prompts plus publishing metadata.\n3. Kie generates the music and a Nano Banana image. Guarded wait/poll loops handle the asynchronous jobs and stop on failure or timeout.\n4. BeatAPI combines the audio and images, then returns the final video URL, title, description, tags, and provider task IDs.\n\n### Setup\n1. **Text API:** Create an OpenAI API key at [https://platform.openai.com/](https://platform.openai.com/) and add it to **OpenAI Chat Model**.\n2. **Image API:** Create a Kie API key at [https://kie.ai/](https://kie.ai/). Add Header Auth with `Authorization: Bearer <KIE_API_KEY>` and bind it to every Kie request.\n3. **AI MV API:** Create a BeatAPI API key at [https://beatapi.io/](https://beatapi.io/). Add Header Auth with `Authorization: Bearer <BEATAPI_API_KEY>` and bind it to both BeatAPI requests.\n4. Run **On form submission** in test mode, submit a brief, and inspect **Final Output**.\n\n### Customization\nConnect **Final Output** to YouTube, Postiz, Google Sheets, Airtable, or your publishing webhook."
