Telegram to Veo 3.1 Short Videos (Gemini + PostWire) n8n

Turn a Telegram text idea into an 8-second vertical Veo 3.1 video—and publish to TikTok, Instagram Reels, and YouTube Shorts

This n8n workflow listens for ideas sent to your Telegram bot, uses Google Gemini to generate a Veo 3.1-ready prompt and platform captions, renders an 8-second 9:16 video, uploads via PostWire, and publishes to TikTok, Instagram Reels, and YouTube Shorts—with results logged to Google Sheets.

What this workflow does

• Telegram trigger: Starts when your Telegram bot receives a new message, ignoring empty messages and slash commands.
• Render started confirmation: Replies in Telegram to confirm the render has begun.
• Gemini content generation: Converts your idea into a Veo 3.1 prompt plus per-platform text for TikTok, Instagram, and YouTube (including a YouTube title).
• Veo 3.1 video creation: Requests an upload URL from PostWire, generates a vertical 8-second clip using Veo 3.1, uploads it to PostWire, and finalizes to obtain a hosted video URL.
• Telegram preview: Sends the generated video back to the chat as a preview.
• Multi-platform publishing: Publishes the video to TikTok, Instagram, and YouTube via PostWire using an idempotency key to prevent duplicate posts on retries.
• Logging + feedback: Appends a success or failure record to Google Sheets and informs you in Telegram with published links or required fixes if any platform fails.

Use cases

• Generate and publish short-form campaigns from a simple “idea” message in Telegram.
• Batch content iteration for SaaS operators who want fast TikTok/Reels/Shorts publishing with automated tracking.
• Automation engineers building an end-to-end AI video pipeline with Gemini + Veo 3.1 and PostWire distribution.
