n8n YouTube Shorts Generator with Leonardo AI, GPT, and ElevenLabs

This n8n workflow automates the creation of engaging YouTube Shorts from a given topic. It leverages the power of AI to generate scripts, create stunning images, and produce natural-sounding voiceovers, streamlining the entire content creation process.

What it does

This workflow orchestrates a series of AI-powered steps to transform a simple topic into a ready-to-publish YouTube Short:

  1. Manual Trigger: The workflow is initiated manually, allowing you to provide a topic for your YouTube Short.
  2. Edit Fields (Set): Sets the initial topic for the short.
  3. OpenAI (Script Generation): Uses OpenAI's GPT to generate a concise script for the YouTube Short based on the provided topic.
  4. OpenAI (Image Prompt Generation): Generates a descriptive image prompt for Leonardo AI based on the generated script.
  5. HTTP Request (Leonardo AI Image Generation): Sends the image prompt to Leonardo AI to generate an image.
  6. Wait: Pauses the workflow for a short period to allow Leonardo AI to process the image generation request.
  7. HTTP Request (Retrieve Leonardo AI Image): Retrieves the generated image from Leonardo AI.
  8. Split Out: Separates the image generation results, handling multiple images if generated.
  9. Aggregate: Combines the image URLs into a single output.
  10. OpenAI (Voiceover Script Generation): Refines the script specifically for ElevenLabs voiceover.
  11. HTTP Request (ElevenLabs Voiceover Generation): Sends the refined script to ElevenLabs to generate an audio file.
  12. Wait: Pauses the workflow to allow ElevenLabs to process the voiceover generation.
  13. HTTP Request (Retrieve ElevenLabs Voiceover): Retrieves the generated audio file from ElevenLabs.
  14. Merge: Combines all the generated assets (script, image, voiceover) into a final output.

Prerequisites/Requirements

To use this workflow, you will need API keys and accounts for the following services:

  • OpenAI: For script and image prompt generation (GPT-3.5 or GPT-4).
  • Leonardo AI: For AI image generation.
  • ElevenLabs: For AI voiceover generation.

Setup/Usage

  1. Import the workflow: Download the JSON provided and import it into your n8n instance.
  2. Configure Credentials:
    • For the OpenAI nodes, create an OpenAI credential and provide your API Key.
    • For the HTTP Request nodes interacting with Leonardo AI, you will need to set up an HTTP Request credential with your Leonardo AI API key and any necessary headers.
    • For the HTTP Request nodes interacting with ElevenLabs, you will need to set up an HTTP Request credential with your ElevenLabs API key and any necessary headers.
  3. Activate the workflow: Ensure the workflow is active.
  4. Execute Manually: Click "Execute workflow" on the "When clicking ‘Execute workflow’" node.
  5. Provide Topic: In the "Edit Fields (Set)" node, replace the placeholder topic with your desired YouTube Short topic.
  6. Run: The workflow will then proceed to generate the script, image, and voiceover.
  7. Review Output: The final "Merge" node will contain all the generated assets, ready for you to download and combine into your YouTube Short.

Publishing videos across multiple platforms with Blotato (Instagram, YouTube)

Description This workflow automates video distribution to 9 social platforms simultaneously using Blotato's API. It includes both a scheduled publisher (checks Google Sheets for videos marked "Ready") and a subworkflow (can be called from other workflows). Perfect for creators and marketers who want to eliminate manual posting across Instagram, YouTube, TikTok, Facebook, LinkedIn, Threads, Twitter, Bluesky, and Pinterest. --- How It Works Scheduled Publisher Workflow Schedule Trigger – Runs daily at 10 PM (configurable). Fetch Video – Pulls video URL and description from Google Sheets where "ReadyToPost" = "Ready". Upload to Blotato – Sends video to Blotato's media service. Broadcast to 9 Platforms – Publishes simultaneously to all connected social accounts. Update Sheet – Changes "ReadyToPost" to "Finished" so it won't repost. --- Subworkflow: Video Publisher (Reusable) Receive Input – Gets URL, title, and description from parent workflow. Fetch Credentials – Pulls Blotato API key from n8n Data Table. Upload & Distribute – Uploads to Blotato, then posts to all platforms. Completion Signal – Returns to parent workflow when done. > 💡 Tip: The subworkflow can be called from ANY workflow - great for posting videos generated by AI workflows, webhook triggers, or manual forms. --- Test Workflow (Optional) Form Submission – Upload a video file with title and description. Upload to Dropbox – Generates shareable URL via "[SUB] Dropbox Upload Link" subworkflow. Trigger Publisher – Calls the subworkflow above to distribute the video. --- Setup Instructions Estimated Setup Time: 20-25 minutes Step 1: Blotato Account Setup Create account at Blotato Dashboard Connect all your social media accounts (most time-consuming step) Go to Settings and copy your account IDs for each platform Go to API Settings and copy your API key Step 2: Configure Workflow Update Social IDs: Open "Assign Social Media IDs" node Replace placeholder IDs with your actual Blotato account IDs: json { "instagramid": "YOURID", "youtubeid": "YOURID", "tiktokid": "YOURID", ... } Create Data Table: Create n8n Data Table named "Credentials" Add columns: service and token Add row: service = blotato, token = YOURAPIKEY Set Up Google Sheet: Create sheet with columns: URL VIDEO, ReadyToPost, Description, Titre (Title) Add video data Set ReadyToPost to "Ready" for videos you want to post Connect Your Sheet: Update "Get my video" node with your Google Sheet ID > ⚙️ Pro Tip: If you don't need the scheduled version, just use the subworkflow and call it from other workflows. --- Use Cases AI Video Workflows: Automatically post videos generated by Veo, Sora, or other AI models to all platforms. Content Schedulers: Queue videos in Google Sheets, let the scheduler post them automatically. Batch Publishing: Generate 10 videos, mark them all "Ready", and let the workflow distribute them. Marketing Campaigns: Coordinate multi-platform launches with a single click. Agencies: Manage multiple client accounts by swapping Blotato credentials in the Data Table. --- Customization Options Remove Unused Platforms: Disconnect any social media nodes you don't use (speeds up execution). Change Schedule: Modify the Schedule Trigger to run multiple times per day or on specific days. Different File Hosts: Replace Dropbox with Google Drive, S3, or Cloudinary in the test workflow. Platform-Specific Captions: Add IF nodes before each platform to customize descriptions or add hashtags. Add Approval Step: Insert a WhatsApp or Telegram notification before posting for manual review. Watermarks: Add a Code node to overlay branding before uploading to Blotato. --- Important Notes ⚠️ Two Workflows in One File: Lines 1-600: Scheduled publisher (checks Google Sheets) Lines 600+: Subworkflow (called by other workflows) ⚠️ Data Table vs. Hardcoding: Scheduled workflow: Hardcoded API keys in HTTP nodes Subworkflow: Uses Data Table for API keys (recommended approach) ⚠️ Why Use the Subworkflow? Can be called from ANY workflow Easier to manage API keys (one place to update) More flexible for complex automation systems
