+PyQt6 Professional Video Player - Prototype
+Author: Dario Pascoal
+
+Description: This is a PyQt6 implementation of a professional video player to demonstrate
+the advantages PyQt6 could bring to the video editor application. This prototype shows:
+
+- Hardware-accelerated video playback with QMediaPlayer
+- Professional video controls and scrubbing
+- Modern UI styling with dark theme
+- Smooth timeline with precise seeking
+- Professional video display with proper aspect ratio
+- Keyboard shortcuts (Space, arrows, etc.)
+- Full-screen capabilities
+- Real-time effects pipeline ready
+
+This serves as a proof-of-concept for upgrading the current Tkinter video editor
+to PyQt6 for better performance and professional features.

+Professional Video Editor for Generated Shorts - PyQt6 Version
+Author: Dario Pascoal
+
+Description: This is a comprehensive video editing application designed specifically for editing 
+short-form video content, fully migrated to PyQt6 for enhanced performance and professional features. 
+
+The application provides a professional timeline-based interface similar to industry-standard 
+video editing software, with features including:
+
+- Multi-track timeline with visual track roads for professional editing workflow
+- Hardware-accelerated video preview with frame-accurate scrubbing
+- Professional editing tools: trim, speed adjustment, volume control, fade effects
+- Real-time effects system with ripple, fade, and text overlays
+- Text overlay capabilities with customizable styling
+- Export functionality with multiple format support
+- Tabbed interface organizing tools into logical categories
+- Dark theme optimized for video editing work
+- Support for multiple video formats (MP4, AVI, MOV, MKV, etc.)
+- Full keyboard control system (Space, arrows, F11, etc.)
+- Professional fullscreen mode with all effects
+
+PyQt6 Advantages:
+- Hardware-accelerated video playback with QMediaPlayer
+- OpenGL timeline rendering for smooth performance
+- Professional UI components and styling
+- Better threading and signal/slot architecture
+- Native multimedia framework integration
+- GPU-accelerated effects pipeline
+- Professional dock system for panels
+- Modern styling with CSS-like stylesheets
+
+Technical Architecture:
+- Uses QMediaPlayer for hardware-accelerated video playback
+- Implements QGraphicsView-based timeline with precise time calculations
+- Signal/slot pattern for clean event handling
+- QThread-based background processing
+- Hardware-accelerated effects pipeline ready for expansion
+- Maintains professional video editing workflow patterns
