Scrape TikTok Trends & Generate AI Videos with Apify, Fal AI & Google Suite

Description

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:
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).
Store Raw Data: It saves the scraped TikTok metadata (text, stats, author info) into a Google Sheet.
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).
Log Prompts: The generated prompt is saved to a separate tab in the Google Sheet.
Video Generation: The prompt is sent to Fal AI (Veo3 model) to generate a new 8-second, vertical (9:16) video with audio.
Wait & Retrieve: The workflow waits for the generation to complete, then retrieves the video file.
Cloud Storage: Finally, it uploads the generated video file to a specific Google Drive folder.

How to set up
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.
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.
Google Drive:
Create a destination folder.
Update the Upload file node with the correct folderId.
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.
