obscure video + - Persistent across sessions + +3. **Status Timer (500ms)** + - Balance between responsiveness and CPU + - Updates duration/file size + - Minimal overhead + +4. **Preset-Based UI** + - Simplified for end users + - Advanced users can use CLI + - Extensible for profiles + +### Current Limitations + +1. **No QML Integration** + - UI is pure Qt Widgets + - Future: Could add QML recording panel + - Benefit: Simpler for now + +2. **No Real-Time Preview** + - Video renderer is placeholder + - Doesn't show recording output + - Would require frame duplication + +3. **No Advanced Settings Dialog** + - All settings via code/CLI + - Future: Settings dialog with tabs + - Current: Keeps UI simple + +--- + +## ✅ Success Criteria + +All success criteria met: + +✅ **Integration** +-
