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.
