OStudi/short-video-generator-AI

What it solves

It provides a free, open-source alternative to paid SaaS tools for converting long-form YouTube videos or local files into viral short-form clips (9:16). It automates the tedious process of finding high-impact moments, cropping video, and adding subtitles.

How it works

1. Transcription: Uses faster-whisper to create a timestamped transcript of the video.
2. Content Analysis: An LLM (OpenAI, Gemini, or MuAPI) classifies the video type (e.g., podcast, tutorial) to tune the highlight detection.
3. Virality Ranking: The LLM scans the transcript using a virality framework to identify emotional peaks, hooks, and revelations, ranking them by score.
4. Selection & Processing: The system deduplicates overlapping clips, selects the top-N candidates, and auto-crops them to the desired aspect ratio.
5. Enhancement: Optionally adds an AI-generated hook at the start of the clip.

Who it’s for

Content creators who want to automate the creation of short-form social media content from longer videos without paying for subscription-based AI clipping tools.
