AI video automation engine - generate & publish YT shorts with Veo-3 or Sora 2

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: 1. 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. 2. 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). 3. 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). 4. Set Scheduling - Add CRON triggers for automatic execution (e.g., twice daily). - Example: 5. Define Variables - File naming conventions: - namevorher = raw 16:9 video - namenachher = final 9:16 video - Set topic = content niche (e.g., history, ocean, futurism). 6. 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. 7. Test End-to-End - Run the workflow manually once. - Verify video rendering, FFmpeg subtitles, Telegram message, YouTube & IG uploads. 8. Go Live - Enable CRON triggers. - Monitor first runs for errors (API limits, FFmpeg paths, token expiry). --- Why Buy This Template You’re not buying a script—you’re buying a production-ready system with a deliberate creative pattern, best-practice formatting, and shipping-grade integrations. It reduces ramp-up from weeks to hours and gives you a flexible base you can keep evolving. ---
