Scrape TikTok trends & generate AI videos with Apify, Fal AI & Google Suite

Automated TikTok Repurposing & Video Generation Workflow

Who’s it for

This workflow is designed for content creators, social media managers, and marketers—specifically those in the career, recruitment, or "job change" (転職/就職) niches. It is ideal for anyone looking to automate the process of finding trending short-form content concepts and converting them into fresh AI-generated videos.

How it works / What it does

This workflow automates the pipeline from content research to video creation:

1. Scrape Data: It triggers an Apify actor (clockworks/tiktok-scraper) to search and scrape TikTok videos related to "Job Change" (転職) and "Employment" (就職).
2. Store Raw Data: It saves the scraped TikTok metadata (text, stats, author info) into a Google Sheet.
3. AI Analysis & Prompting: An AI Agent (via OpenRouter) analyzes the scraped video content and creates a detailed prompt for a new video (concept, visual cues, aspect ratio).
4. Log Prompts: The generated prompt is saved to a separate tab in the Google Sheet.
5. Video Generation: The prompt is sent to Fal AI (Veo3 model) to generate a new 8-second, vertical (9:16) video with audio.
6. Wait & Retrieve: The workflow waits for the generation to complete, then retrieves the video file.
7. Cloud Storage: Finally, it uploads the generated video file to a specific Google Drive folder.

How to set up

1. Credentials: Configure the following credentials in n8n:
   • Apify API: (Currently passed via URL query params in the workflow, recommended to switch to Header Auth).
   • Google Sheets OAuth2: Connect your Google account.
   • OpenRouter API: For the AI Agent.
   • Fal AI (Header Auth): For the video generation API.
   • Google Drive OAuth2: For uploading the final video.
2. Google Sheets:
   • Create a spreadsheet.
   • Note the documentId and update the Google Sheets nodes.
   • Ensure you have the necessary Sheet names (e.g., "シート1" for raw data, "生成済み" for prompts) and columns mapped.
3. Google Drive:
   • Create a destination folder.
   • Update the Upload file node with the correct folderId.
4. Apify:
   • Update the token in the HTTP Request and HTTP Request1 URLs with your own Apify API token.

Requirements

• n8n Version: 1.x or higher (Workflow uses version 4.3 nodes).
• Apify Account: With access to clockworks/tiktok-scraper and sufficient credits.
• Fal.ai Account: With credits for the fal-ai/veo3 model.
• OpenRouter Account: With credits for the selected LLM.
• Google Workspace: Access to Drive and Sheets.

How to customize the workflow

• Change the Niche: Update the searchQueries JSON body in the first HTTP Request node (e.g., change "転職" to "Cooking" or "Fitness").
• Adjust AI Logic: Modify the AI Agent system prompt to change the style, tone, or structure of the video prompts it generates.
• Video Settings: In the Fal Submit node, adjust bodyParameters to change the duration (e.g., 5s), aspect ratio (e.g., 16:9), or disable audio.
• Scale: Increase the amount in the Limit node to process more than one video per execution.
