Generate VEED AI talking head videos from sheet rows with OpenAI or ElevenLabs

Description

A production-ready n8n workflow that generates AI avatar videos from images and text using VEED Fabric 1.0, with flexible multi-platform publishing capabilities.

Key Capabilities

Unlimited Scale
Process any number of videos**: Sequential processing ensures each video is fully generated and published before moving to the next
Batch processing**: Add multiple video requests to Google Sheet and let the workflow process them automatically
No context mixing**: Each video maintains its own configuration throughout the entire pipeline

Flexible Publishing
Per-video platform selection**: Each video can target different platforms (e.g., Video 1 → Instagram+YouTube, Video 2 → Telegram only)
Optional publishing**: Leave PLATFORMS column empty to generate videos without publishing (videos saved to Drive)
Supported platforms**: Instagram Reels, YouTube/Shorts, Facebook, Telegram, Threads
Platform-specific formatting**: Automatic optimization for each platform's requirements

Smart Processing
Two TTS providers**: Choose OpenAI or ElevenLabs per video
Configurable quality**: Select resolution (480p/720p) and aspect ratio (9:16, 16:9, 1:1) per video
Approval workflow**: Review videos before publishing with email approve/reject buttons
Error handling**: Automatic error detection with detailed email notifications

Status Tracking
Real-time status updates**: Google Sheet updates as workflow progresses (new → processing → published)
Detailed results**: Per-platform success/failure tracking with post URLs
Email reports**: Comprehensive publishing reports with links to all posted content
