This n8n workflow is an end-to-end AI-powered video generation pipeline that takes a dataset of sci-fi book, generates reviews with GenAI, dynamically injects assets into After Effects via Nexrender, and automatically produces fully rendered videos — ready for publishing.

It demonstrates: • AI content generation inside render jobs • Dynamic After Effects templating • Adaptive composition logic • Fully automated creative production at scale

Built as a demo for the Nexrender n8n integration, it shows how to turn raw ideas into finished video content with zero manual editing.

Requirements:

  1. Nexrender Trial - https://www.nexrender.com/get-trial,
  2. N8N - https://n8n.io/,
  3. Fal.ai - https://fal.ai/,
  4. After Effects Project file - https://drive.google.com/file/d/1XmDcBMM34IFQ2Cv28pzumDmk2OwW2_9q/view?usp=share_link,
  5. Nexrender Integration - https://n8n.io/integrations/nexrender/

How It Works: • Imports a sci-fi books dataset into n8n • Uses GenAI (ChatGPT) to generate book reviews and narrative content • Cleans and structures the AI output for video rendering • Dynamically injects text and assets into an After Effects template via n8n Nexrender Integration • Submits the job to Nexrender for rendering • Generates AI-powered visuals inside the render job • Automatically adjusts composition length based on each review • Outputs a fully produced video — no manual editing required
