# AI YouTube Shorts Generator
[](https://muapi.ai?utm_source=github&utm_medium=badge&utm_campaign=ai-youtube-shorts-generator)
**The open-source alternative to Opus Clip, Vidyo.ai, Klap, SubMagic, 2short.ai, and other AI clipping tools.** Drop in any long-form YouTube video and get back ranked, viral-ready 9:16 shorts — for free, with no per-clip credits, no watermarks, and full control over the highlight algorithm.
Built for creators, agencies, and developers who don't want to pay $20–$300/month or be capped on minutes processed. Uses GPT-class LLM highlight detection and Whisper transcription to extract the most viral-worthy moments and auto-crop them vertically for TikTok, Reels, and Shorts.
> **Building your own Opus Clip–style SaaS?** Skip the infra and ship on the same APIs that power this repo:
> - [AI Clipping API](https://muapi.ai/playground/ai-clipping?utm_source=github&utm_medium=readme&utm_campaign=ai-youtube-shorts-generator) — end-to-end clip selection + render
> - [Auto-Crop API](https://muapi.ai/playground/autocrop?utm_source=github&utm_medium=readme&utm_campaign=ai-youtube-shorts-generator) — vertical reframing only

## Features
- **🎬 YouTube In, Vertical Out**: Hand it any YouTube URL — get back N viral-ready 9:16 mp4s
- **🔀 Two Modes — API (fast) or Local (offline)**: Default `--mode api` uses MuAPI for download/transcription/cropping; `--mode local` runs entirely on your machine with `yt-dlp`, `faster-whisper`, and `ffmpeg`/`opencv`, and lets you pick OpenAI or Gemini for highlight ranking
- **🤖 Virality-Aware Highlight Selection**: Clips ranked on hooks, emotional peaks, opinion bombs, revelation moments, conflict, quotable lines, story peaks, and practical value — not just generic "interesting"
- **📈 Score + Hook + Reason for Every Clip**: Each highlight comes with a viral score, an opening hook line, and a one-sentence explanation of why it works
- **🎤 Whisper Transcription, Your Choice**: Cloud (`/openai-whisper` via MuAPI) or local (`faster-whisper`, CPU or CUDA) — same downstream output shape
- **🧩 Long-Video Aware**: Videos over 30 minutes are auto-chunked with overlap so nothing gets missed
- **♻️ Smart Dedupe**: Overlapping highlights are collapsed by score so you never get two near-duplicate clipExcerpt of 14,504 characters
