## Overview

ClipGenius AI turns a YouTube URL into captioned, music-backed short clips, stores clip metadata and upload status, and lets users review, delete, or upload clips. The main flow runs from the React home page through the API route, then download, transcription, AI moment selection, FFmpeg processing, and persistence; upload is a separate user-triggered path. The README documents YouTube uploads, metadata generation, captions, and music. Some backend service wiring is supported by the route excerpt and README workflow, but unsampled implementation details are represented only at subsystem level.
