Generate AI historical videos and upload to YouTube with Telegram approval\n\n## Who’s it for\nThis workflow is ideal for:\n- Content creators producing daily historical or educational videos  \n- YouTube automation enthusiasts building AI-driven channels  \n- Educators sharing engaging historical facts in short-form video format  \n- Anyone creating an automated AI video pipeline with human approval  \n\n## How it works\nThis workflow automates the full pipeline of generating and publishing historical videos:\n\n1. Triggers daily at 1 AM and initializes retry tracking (maximum 3 attempts)  \n2. Fetches historical events for the current date and selects one randomly  \n3. Uses Google Gemini to generate a cinematic text-to-video script  \n4. Sends the prompt to fal.ai (Hunyuan LoRA) to generate a short video  \n5. Polls the generation status every 30 seconds until the video is ready  \n6. Downloads the generated video and sends it to Telegram with context  \n7. Waits for manual approval via Telegram  \n8. If approved → uploads the video to YouTube and sends a confirmation message  \n9. If declined → retries with a new event (up to 3 attempts total)  \n\n## How to set up\n1. Import the workflow into n8n  \n2. Configure your Telegram credentials  \n3. Set your Telegram Chat ID using a variable or Set node (avoid hardcoding)  \n4. Configure HTTP Header Auth credentials for fal.ai (API key required)  \n5. Set up Google Gemini API credentials  \n6. Connect your YouTube account using OAuth2  \n7. (Optional) Adjust the schedule time in the trigger node  \n8. Activate the workflow  \n\n## Requirements\n- n8n (cloud or self-hosted)  \n- fal.ai account and API key (for video generation)  \n- Google Gemini API access  \n- YouTube account with upload permissions  \n- Telegram account for approval notifications  \n\n## How to customize the workflow\n- Adjust retry limits in the retry logic node  \n- Modify video parameters (resolution, frames, aspect ratio) in the fal.ai request  \n- Change the script style by editing the Gemini prompt  \n- Replace the historical events API with another content source  \n- Customize Telegram messages or approval flow  "},"typeVersion":1}],"pinData":{},"connections":{"Submit to fal.ai":{"main":[[{"node":"Check Video Generation Status","type":"main","index":0}]]},"Check Retry Limit":{"main":[[{"node":"Send Stop Message","type":"main","index":0}],[{"node":"Fetch Historical Events","type":"main","index":0}]]},"Upload to YouTube":{"main":[[{"node":"Upload Confirmation Message","type":"main","index":0}]]},"Check User Approval":{"main":[[{"node":"Upload to YouTube","type":"main","index":0}],[{"node":"Increment Retry Counter","type":"main","index":0}]]},"Download Video File":{"main":[[{"node":"Prepare Approval Message","type":"main","index":0}]]},"Get Generated Video":{"main":[[{"node":"Extract Video Metadata","type":"main","index":0}]]},"Gemini Language Model":{"ai_languageModel":[[{"node":"Generate Cinematic Script with AI","type":"ai_languageModel","index":0}]]},"Extract Video Metadata":{"main":[[{"node":"Download Video File","type":"main","index":0}]]},"Wait for User Approval":{"main":[[{"node":"Check User Approval","type":"main","index":0}]]},"Fetch Historical Events":{"main":[[{"node":"Select Random Historical Event","type":"main","index":0}]]},"Increment Retry Counter":{"main":[[{"node":"Check Retry Limit","type":"main","index":0}]]},"Is Generation Complete?":{"main":[[{"node":"Get Generated Video","type":"main","index":0}],[{"node":"Wait 30 Seconds Before Retry","type":"main","index":0}]]},"Send Video for Approval":{"main":[[{"node":"Wait for User Approval","type":"main","index":0}]]},"Prepare Approval Message":{"main":[[{"node":"Send Video for Approval","type":"main","index":0}]]},"Schedule (Daily at 1 AM)":{"main":[[{"node":"Initialize Workflow State","type":"main","index":0}]]},"Initialize Workflow State":{"main":[[{"node":"Check Retry Limit","type":"main","index":0}]]},"Upload Confirmation Message":{"main":[[{"node":"Send Upload Confirmation","type":"main","index":0}]]},"Wait 30 Seconds Before Retry":{"main":[[{"node":"Check Video Generation Status","type":"main","index":0}]]},"Check Video Generation Status":{"main":[[{"node":"Is Generation Complete?","type":"main","index":0}]]},"Select Random Historical Event":{"main":[[{"node":"Generate Cinematic Script with AI","type":"main","index":0}]]},"Generate Cinematic Script with AI":{"main":[[{"node":"Submit to fal.ai","type":"main","index":0}]]}}}
