n8n Workflow: URL to Branded Video Ads (Webhook + AI + JSON2Video)

Turn any website URL into a branded, captioned video ad—end to end

This n8n workflow takes a website or product URL via webhook, crawls and analyzes the content with Tavily and Google Gemini, generates a 3-scene branded ad with OpenAI (images + voiceover), renders the movie with JSON2Video, burns in styled subtitles, and stores the final MP4 in Google Drive with a job-based status endpoint.

What this workflow does

• Webhook intake (POST): Receives a URL and immediately returns a response containing a jobId so you can track progress.
• Site crawling & brand extraction: Crawls the provided URL using Tavily (including image links), then uses Google Gemini to extract structured brand/product text, links, and up to three image URLs.
• 3-scene ad creation: Uses Google Gemini to draft image-generation prompts (brand, product, lifestyle), fetches referenced website images, and generates three scene images with OpenAI Images, uploading them to a job folder in Google Drive.
• Voiceover generation: Creates a short 3-scene script with Google Gemini, generates narration audio with OpenAI Audio, and uploads the audio to Google Drive.
• JSON2Video rendering + subtitles: Assembles a 3-scene JSON2Video movie using the Drive-hosted assets, polls JSON2Video until rendering succeeds, then sends the video back to JSON2Video to burn in styled subtitles and polls again.
• Delivery & status: Downloads the final captioned MP4 and uploads it to Google Drive using the jobId. A separate status-check webhook searches Drive and returns processing/completed JSON.

Use cases

• SaaS teams generating branded video ad variants from landing pages.
• Marketing ops automating captioned 3-scene ads for campaigns.
• n8n engineers building a URL-to-video pipeline with webhook-driven jobs.
