You fill a form with a simple idea in plain English. A ChatGPT AI model converts it into a detailed, professional VEO3 prompt (subject, camera motion, lighting, audio, style). The optimized prompt is sent to fal.ai which runs Google's VEO3 model to generate an 8-second video with native audio. The workflow polls for completion, downloads the MP4, saves it to Google Drive, and emails you the link.\n\n## How it works\n- **1. Form \u2014 Video Request** collects your email, the video idea, and a style choice\n- **2. AI Agent \u2014 Optimize VEO3 Prompt** turns the plain-English idea into a structured VEO3 prompt and a short title, returned as strict JSON\n- **OpenAI Chat Model** the language model attached to the AI Agent\n- **3. Code \u2014 Parse Prompt and Prepare** safely parses the JSON, builds a filename-safe title, and sets aspect ratio and duration\n- **4. HTTP \u2014 Submit to fal.ai VEO3** queues the generation job and returns a request_id\n- **5. Wait \u2014 30 Seconds** gives VEO3 time before the first status check\n- **6. HTTP \u2014 Check VEO3 Status** reads the job status\n- **7. IF \u2014 Video COMPLETED?** routes to download when ready, otherwise to retry\n- **7b. Wait \u2014 Retry 30s** waits then loops back to the status check\n- **8. HTTP \u2014 Get Video URL** fetches the finished job result with the MP4 URL\n- **9. HTTP \u2014 Download MP4** downloads the video binary\n- **10. Google Drive \u2014 Save MP4** saves the file with the AI title as filename\n- **11. Gmail \u2014 Send Video Link** emails you the Drive link\n\n## Set up steps\n1. **fal.ai API (runs VEO3)** \u2014 create a free account at https://fal.ai, make an API key at https://fal.ai/dashboard/keys, and replace `YOUR_FAL_AI_API_KEY` in nodes 4, 6, and 8. VEO3 generation costs fal.ai credits \u2014 check current pricing at https://fal.ai/models/fal-ai/veo3\n2. **OpenAI** \u2014 in **OpenAI Chat Model**, connect your OpenAI API credential and pick any current ChatGPT model from the dropdown\n3. **Google Drive** \u2014 create a folder for your videos, copy its folder ID from the URL after /folders/, replace `YOUR_GDRIVE_FOLDER_ID` in node 10, and connect Google Drive OAuth2\n4. **Gmail** \u2014 connect Gmail OAuth2 in node 11. The recipient address comes from the form, so no email needs to be hard-coded\n5. Activate the workflow, open the Form URL, type a video idea in plain English, and submit. Wait about 2-3 minutes and check your email for the Drive link" }, "typeVersion": 1 }, { "id": "fd59df79-1fc1-47b2-9a0d-043d17acaf90", "name": "Section \u2014 Form Input and AI Prompt", "type": "n8n-nodes-base.stickyNote", "position": [ -400, -224 ], "parameters": { "color": 5, "width": 756, "height": 484, "content": "## Form Input and AI Prompt\nUser types a plain-English idea and picks a style.
