AI Video Automation Engine - Generate & Publish YT Shorts with Veo-3 or Sora 2

Description

Product Overview

Scale short-form content without scaling your team. This template turns idea discovery → prompt & text generation → Veo-3 video rendering → vertical formatting → multi-channel publishing into one cohesive pipeline. It’s built natively on n8n, so you keep full control, self-host if you want, and extend every step with your own logic.

What’s Inside (Modular Building Blocks)

Idea Engine** – AI generates concise, surprising facts and a visual metaphor per topic (swappable LLM/provider).
Prompt & Text Composer** – Crafts an 8-second, cinematic Veo-3 prompt + title, caption, description, hashtags, tags in a consistent brand voice.
Renderer Integration** – Kie.ai → Veo-3 (16:9, 1080p) for fast, cinematic clips.
Vertical Formatter** – FFmpeg pipeline converts to 1080×1920, adds top/bottom text bands (15–20 words), and preserves loop smoothness.
Multi-Channel Distribution** – Uploads to YouTube Shorts and Telegram for internal review/approvals.
Scheduler & Orchestration** – CRON triggers, retries, and lightweight polling make the system dependable for daily publishing.

Why These Components (and why they work together)

Veo-3 via Kie.ai* provides a sweet spot of *quality + speed**, ideal for short loops where style coherence matters.
n8n* brings *vendor-neutral orchestration**: swap LLMs, add rate limits, branch flows, or trigger on events—without rewriting your stack.
FFmpeg* ensures a *platform-native look** (9:16, crisp text bands, no blurry hacks).
Separation of concerns* (idea → text → render → edit → publish) makes it easy to *A/B test** any stage independently.

Key Benefits

Hands-Free Consistency** – Daily output with a repeatable creative pattern that audiences recognize.
Brand-Safe Copy** – Titles, descriptions, and hashtags follow a controlled structure—polished by design.
Time Savings** – Replace fragmented tooling with one pipeline; no manual re-formatting, captioning, or re-uploads.
Creator-Grade Quality** – Cinematic loops optimized for watch time and retention on Shorts/Reels.
Own Your Stack** – Self-hosted orchestration and storage; no lock-in.

Reuse & Extension Ideas

Topic CMS** – Feed topics from Google Sheets / Notion and mark each as “published”—perfect for content calendars.
Multi-Language** – Duplicate the text composer for EN/DE outputs; upload the same clip with localized metadata.
Thumbnail/Preview Track** – Add an image generator step for platform cards or YouTube custom thumbnails.
Analytics Feedback Loop** – Fetch video performance, score ideas, and prioritize winning angles automatically.
Compliance & Fact Trails** – Store sources next to each post for quick audits and edits.
Storage & Delivery** – Push masters to S3/Backblaze, serve via CDN for faster IG ingestion.
More Channels** – Add TikTok, X, LinkedIn publishers or a newsletter export.
A/B Creative** – Render multiple Veo-3 seeds, rotate captions/CTAs, and compare retention.

Who It’s For

Agencies** wanting repeatable, branded Shorts at scale.
Creators & Media Teams** who need daily output with minimal overhead.
Product Marketing** looking to convert docs/reports into snackable, evergreen video facts.
Startups** building audience fast without adding headcount.

Technical Notes (at a glance)

Orchestration:** n8n (self-hosted or cloud)
Video:** Veo-3 via Kie.ai (16:9 render → FFmpeg vertical remaster 1080×1920)
Text Stack:** Any LLM provider (swappable); outputs normalized for each platform
Distribution:** YouTube Data API v3, Telegram Bot API
Security:** API keys via n8n credentials/ENV; public URL endpoint only serves whitelisted .mp4 filenames with proper headers
Reliability:** CRON triggers, bounded retries/polling, and safe fallbacks to avoid stuck runs

Who to use it

To enhance the completeness, add specific step-by-step setup instructions for users to implement the workflow easily:

Install Prerequisites
Set up n8n on your server or local machine (production mode with reverse proxy).
Install FFmpeg and ensure fonts (e.g., DejaVu Sans) are available.

Configure API Credentials
Get a Perplexity API key for idea generation.
Request a Kie.ai API key for Veo-3 video rendering.
Set up YouTube OAuth2 (enable YouTube Data API v3 in Google Cloud Console).
Create a Telegram bot token via BotFather.
Store all keys as environment variables in n8n (avoid hardcoding).

Prepare Storage
Create a working directory accessible by n8n with read/write rights.
Ensure enough disk space for video caching (approx. 50–200 MB per run).

Set Scheduling
Add CRON triggers for automatic execution (e.g., twice daily).
Example:
0 12 04 * * * → 04:12 AM daily
0 12 16 * * * → 04:12 PM daily

Define Variables
File naming conventions:
name_vorher = raw 16:9 video
name_nachher = final 9:16 video
Set topic = content niche (e.g., history, ocean, futurism).

Build Workflow Steps in n8n
Idea Generation: Perplexity node for viral fact.
Prompt Agent: Expand into full package (prompt, caption, hashtags).
Video Generation: Kie.ai Veo-3 API request (poll until success).
Download & Edit: Save raw file, convert to 9:16 with FFmpeg overlays.
Notifications & Uploads:
Telegram node → send video.
YouTube node → upload with title, description, tags.


Test End-to-End
Run the workflow manually once.
Verify video rendering, FFmpeg subtitles, Telegram message, YouTube & IG uploads.

Go Live
Enable CRON triggers.
Monitor first runs for errors (API limits, FFmpeg paths, token expiry).

Why Buy This Template
