Movie Maker
Record narrated walkthroughs of your Gallia project. Captures browser tab video + microphone audio, detects silence, and provides smart playback that skips dead air. Videos are organized in a Library with thumbnails, duration, and talking/silence breakdowns.
Input: User clicks Record in toolbar or Movie Maker UI, or Claude executes a script
Output: .webm video files stored in project content, viewable in the Library
Architecture
Recording runs in the parent frame (index.html toolbar) to avoid iframe getDisplayMedia restrictions. If that fails, falls back to a popup tab (record-popup.html). Communication between components uses BroadcastChannel (popup mode) or postMessage (parent mode).
