I Built an AI That Turns Raw Gameplay into TikTok, YouTube, and Trailer Clips — Automatically

Every time I watch a stream, I think the same thing: there are 10 incredible moments buried in 3 hours of footage that no one will ever see. Editing is the bottleneck. It takes skill, time, and software most people don't want to learn. So the best gaming moments just... disappear. I built clipforge to fix that. Upload a gameplay video. Get three ready-to-post formats back — automatically. What it produces From a single upload (mp4, mov, or mkv — up to 10 minutes): TikTok/Reels clip — 60 seconds max, vertical 9:16 crop, auto-captions via Whisper YouTube highlight reel — top moments sequenced, up to 10 minutes Cinematic trailer — 90 seconds, fast cuts + slow-mo climax on the best moment All three come back as a single ZIP download. How the pipeline works Upload video ↓ Scene detection (PySceneDetect) ↓ Highlight scoring (librosa RMS energy) ↓ Clip selection (top N by score) ↓ Format assembly (moviepy) ├── TikTok: best moment, vertical crop, captions ├── YouTube: top moments concatenated
