🎬 Automate video creation from voice input with HeyGen, GPT-5 & social publishing

⚡ 2,751 views · 🎬 Content Creation & Video

💡 Pro Tip — Since TikTok doesn’t have a public API, getting data usually means fragile HTTP scraping. ScraperNode is a community node that gives you clean JSON for TikTok profiles, videos, and comments — drop it into your workflow and skip the parsing.

Description

This workflow contains community nodes that are only compatible with the self-hosted version of n8n.

Automate Video Creation from Voice Input with HeyGen & n8n

👥 Who is this for?

This workflow is ideal for:

• Content creators who want to turn ideas into videos in minutes
• Marketers managing multi-platform video campaigns

💡 What problem is this workflow solving?

Creating and publishing videos across TikTok, YouTube, Instagram and more is:

• Hard to scale without automation

This workflow solves it by turning a voice note into a complete AI video — scripted, generated, and published automatically.

1. Capture idea via Telegram voice note
2. Transcribe audio to text using OpenAI Whisper
3. Generate script, title, and caption with GPT-5
4. Create avatar video with HeyGen based on your script
5. Save final video to Google Drive and log metadata in Google Sheets
6. Upload video to Blotato
7. Auto-publish to 9 platforms (TikTok, YouTube Shorts, Instagram, LinkedIn, Facebook, Twitter (X), Threads, Bluesky, Pinterest)
8. Send Telegram notification once published
