UGC Single Video Generator (n8n + AI)

Automatically generate authentic User-Generated Content (UGC) videos from a simple form submission, powered by n8n, Anthropic, and KIE.AI video generation.

Overview

This workflow automates the process of creating influencer-style promotional videos.
Users describe the type of video and influencer, optionally let AI write the script, and select the video’s aspect ratio.
The workflow then generates a complete UGC-style MP4 video using AI, returning a video link automatically.

How It Works

  1. Form Submission

    • A form asks the user for:
      • Video description
      • Influencer type
      • Whether to auto-generate a script
      • Optional custom script
      • Aspect ratio (9:16 or 16:9)

  2. AI Script Generation

    • If “generate script” is checked, the workflow calls Anthropic Claude to produce a short, natural UGC-style script based on the video description and influencer type.

  3. Prompt Building

    • Combines description, script, and influencer details to create structured text prompts for video generation.

  4. Video Generation

    • Sends prompts to the KIE.AI Video API (veo3_fast model) to generate a realistic influencer-style video.

  5. Video Retrieval

    • Fetches the finished MP4 file and returns the link automatically.

Workflow Structure

Step Node Description
1 Form Trigger Collects user input through a custom web form.
2 Edit Fields Normalizes and prepares fields for downstream use.
3 Script Decision Checks if the user wants to auto-generate or use a custom script.
4 HTTP Request (Anthropic) Generates a short script using Claude.
5 Determine Final Script Merges AI or manual script with user input.
6 Create Prompts Builds natural prompts for image/video generation.
7 Generate Video (KIE.AI) Sends request to the KIE.AI API to produce the video.
8 Check Video Success Confirms if the API returned a success code.
9 Get Video File Retrieves the video download link using the task ID.
10 Output Result Outputs video URL and status as JSON.
