kai-deun/Clipping-AI ? reverse-engineered prompt

Build me a simple app called Clipping AI that helps turn longer videos into short highlight clips.

I want to be able to paste a video link or upload a local video, have it process the footage, find the most interesting moments with AI, and then export clean short clips I can save and share. A basic web interface is fine, with a place to add the source, see processing status, preview the results, and download the final clips. If it makes sense, use a local model for the AI part so it can run without paid services.

Please include the backend and frontend so I can run the whole thing from this repo on Windows with a simple start flow. Since there are files related to video downloading and rendering, wire those parts together into one usable experience instead of just test scripts. Make it reasonably polished, handle common errors, and keep sample media support for testing. If you need details, look up current docs online and make sensible choices.
