MovieShort AI is a free, open-source tool that automatically extracts the best moments from full-length movies and formats them as YouTube Shorts, TikTok, Reels. It uses AI to score every scene, tracks people on screen with computer vision, crops to vertical 9:16, and generates word-level subtitles - all locally on your machine. No cloud. No subscriptions. Built on PySceneDetect, faster-whisper, OpenCV, and FFmpeg, it runs on Python and gives you full control over the output.

Hey Product Hunt! 👋 I built MovieShort AI because I was tired of paying $20-50/month to tools like Opus Clip and Klap just to turn movie scenes into Shorts. And every time I used them, I hit the same wall: watermarks, minutes limits, and zero control over the output. So I asked myself — what if this just ran on my own machine, for free? I'm a solo dev, and over a few weekends I wired up PySceneDetect for scene detection, OpenCV for person tracking, faster-whisper for word-level subtitles, and DeepSeek/Gemini to score scenes from 1-10 based on movie context (not just visual activity — actual narrative quality). I added a vertical crop pipeline with blurred backgrounds, a mirror+contrast mode that helps dodge Content ID, and batch processing so you can throw a whole folder at it. The result: a ~102-minute film costs about $0.70 to process. No monthly fees. No watermarks. Full source code in your hands. It's MIT licensed, so you can fork it, extend it, or build a SaaS on top of it if you want. I just wanted to put this out there and see what the community does with it. Would love your feedback — especially on the AI scoring and subtitle accuracy. Let's make movie content creation accessible to everyone.

this looks really solid, especially love that it runs fully local. one thing that would genuinely help though is adding a way to preview the suggested clips before rendering, like a thumbnail timeline or quick scrub view, so you can toss the ones that technically scored high but just feel off contextually. would save a lot of reprocessing time honestly
