🔧 Automated Video Generator (n8n Workflow)

🚀 Features

  • End-to-End Video Creation from user idea or transcript

  • AI-Powered Scriptwriting using LLMs (e.g., DeepSeek via OpenRouter)

  • Voiceover Generation with customizable TTS voices

  • Image Scene Generation using generative models like together.ai

  • Clip Creation & Concatenation into a full video

  • Dynamic Caption Generation with styling options

  • Google Drive & Sheets Integration for asset storage and progress tracking

⚙️ How It Works

User Submits Form with:

  • Main topic or transcript
  • Desired duration
  • TTS voice
  • Visual style (e.g., Pixar, Lego, Cyberpunk)
  • Image generation provider

AI generates a script: A catchy title, description, hook, full script, and CTA using a language model.

Text-to-Speech (TTS): The script is turned into audio using the selected voice, with timestamped captions generated.

Scene Segmentation: The script is split into 5–6 second segments for visual storyboarding.

Image Prompt Creation: Each scene is converted into an image prompt in the selected style (e.g., "anime close-up of a racing car").

Image Generation: Prompts are sent to together.ai or fal.ai to generate scenes.

Clip Creation: Each image is turned into a short video clip (Ken Burns-style zoom) based on script timing.

Video Assembly:

  • All clips are concatenated into a single video.
  • Captions are overlaid using the earlier timestamps.
  • Final Output is uploaded to Google Drive, Telegram and links are saved in Google Sheets.

🛠 Inital Setup

🗣️ 1. Set Up TTS Voice (Text-to-Speech)

Run your TTS server locally using Docker.

🧰 2. Set Up NCA-Toolkit

The nca-toolkit appears to be a custom video/image processing backend used via HTTP APIs:

http://host.docker.internal:9090/v1/image/transform/video

http://host.docker.internal:9090/v1/video/concatenate

http://host.docker.internal:9090/v1/ffmpeg/compose

🔧 Steps:

Clone or build the nca-toolkit container (if it's a private tool):

Ensure it exposes port 9090.

It should support endpoints for:

Image to video (zoom effect)

Video concatenation

Audio + video merging

Caption overlay via FFmpeg

Run it locally with Docker:

docker run -d -p 9090:80 your-nca-toolkit-image

🧠 3. Set Up together.ai (Image Generation) (Optional You can use ChatGPT API Instead)

This handles image generation using models like FLUX.1-schnell.

🔧 Steps:
Create an account at: https://www.together.ai

Generate your API key
