n8n YouTube Video Automation with AI and HeyGen

This n8n workflow automates the end-to-end process of generating YouTube video ideas, creating scripts, and potentially preparing for avatar video generation using AI. It leverages Google Sheets for content management, OpenAI for AI-driven text generation, and includes placeholders for video creation and publishing.

What it does

This workflow streamlines the content creation process for YouTube by:

1. Triggering on Schedule: Initiates the workflow at a predefined interval to check for new content ideas.
2. Fetching Content from Google Sheets: Reads a list of video ideas or topics from a specified Google Sheet.
3. Filtering for New Ideas: Identifies new, unprocessed video ideas by checking a "Published" status.
4. Generating Video Script with AI: Uses an OpenAI Chat Model (via an AI Agent) to generate a detailed video script based on the provided idea.
5. Structuring AI Output: Parses the AI-generated script into a structured format (e.g., JSON) for easy use in subsequent steps.
6. Updating Google Sheet: Marks the processed video idea in the Google Sheet as "Published" to prevent reprocessing.
7. Sending Email Notification: Notifies a specified email address about the successful generation of a new video script.
8. Placeholder for Video Creation (HeyGen/Avatar Videos): Includes an HTTP Request node, likely intended for integration with a video generation service like HeyGen (as suggested by the directory name), to create avatar videos from the generated script.
9. Placeholder for YouTube Upload: Includes a YouTube node, indicating the intention to upload the generated video to YouTube.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance.
• Google Account: For Google Sheets integration. You will need to configure Google Sheets credentials in n8n.
• OpenAI API Key: For the AI Agent and OpenAI Chat Model nodes. You will need to configure OpenAI credentials in n8n.
• SMTP Server/Email Service: For the "Send Email" node to send notifications.
• HeyGen Account (Optional, but likely intended): If you plan to use HeyGen for avatar video generation, you will need an account and its API credentials.
• YouTube Account (Optional, but likely intended): If you plan to upload videos directly to YouTube, you will need a YouTube account and its API credentials.

Setup/Usage

1. Import the Workflow:

   • Download the provided JSON file.
   • In your n8n instance, click "Workflows" in the left sidebar.
   • Click "New" and then "Import from JSON".
   • Paste the JSON content or upload the file.

2. Configure Credentials:

   • Locate the "Google Sheets" node and configure your Google Sheets API credentials.
   • Locate the "OpenAI Chat Model" node and configure your OpenAI API credentials.
   • Locate the "Send Email" node and configure your SMTP or email service credentials.
   • If using HeyGen or YouTube, configure the respective credentials for the "HTTP Request" and "YouTube" nodes.

3. Configure Google Sheet:

   • Create a Google Sheet with a column for video ideas and another for a "Published" status (e.g., TRUE/FALSE).
   • Update the "Google Sheets" node to point to your specific spreadsheet and sheet name, and configure the column mappings.

4. Configure AI Agent:

   • Review the prompts and settings within the "AI Agent" and "OpenAI Chat Model" nodes to ensure they align with your desired video script generation style and content.
   • Adjust the "Structured Output Parser" if your desired output format from the AI changes.

5. Review and Customize:

   • Examine the "HTTP Request" node. This node is currently a placeholder and would need to be configured with the specific HeyGen API endpoint, authentication, and payload to generate a video from the AI-generated script.
   • Examine the "YouTube" node. This node is also a placeholder and would need to be configured for uploading the generated video, including title, description, tags, and privacy settings.
   • Adjust the "Schedule Trigger" to your preferred interval for checking new ideas.
   • Modify the "Send Email" node to specify the recipient, subject, and body of the notification email.

6. Activate the Workflow:

   • Once all configurations are complete, save the workflow and activate it.
