Professional Video Editor for Generated Shorts
Author: Dario Pascoal
Description: This is a comprehensive video editing application designed specifically for editing
short-form video content. 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
- Real-time video preview with frame-accurate scrubbing
- Professional editing tools: trim, speed adjustment, volume control, fade effects
- 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.)
The application is built using Python's Tkinter for the GUI, OpenCV for basic video processing,
and optionally MoviePy for advanced video editing features. It's designed to be educational,
showing how professional video editing interfaces work while remaining accessible to beginners.
Technical Architecture:
- Uses threading for non-blocking video playback and processing
- Implements canvas-based timeline with precise time-to-pixel calculations
- Supports both MoviePy (full features) and OpenCV (basic features) backends
- Maintains professional video editing workflow patterns
- Provides real-time preview updates during editing operations
This file serves as the main entry point for the video editing functionality and can be
integrated into larger applications or run as a standalone tool.

Professional Video Editing Interface
This class provides a complete video editing interface with timeline controls,
real-time preview, and professional editing tools. It's designed to mimic the
workflow of professional video editing software while remaining accessible
to beginners.
Key Features:
- Multi-track timeline with visual separation (road lines)
- Frame-accurate video scrubbing and playback
- Professional editing tools (trim, speed, volume, effects)
- Real-time preview with synchronized timeline
- Tabbed tool interface for organized workflow
- Support for multiple video formats
- Export functionality with timestamp-based naming
The interface uses a dark theme optimized for video editing work and provides
both mouse and keyboard controls for efficient editing workflow.
Attributes:
parent: Parent window or None for standalone operation
shorts_folder: Directory path for video files
current_video: Path to currently loaded video file
current_clip: Video clip object (MoviePy or OpenCV)
timeline_*: Various timeline state and control variables
colors: Dictionary defining the dark theme color scheme
fonts: Dictionary defining typography for different UI elements

Initialize the Professional Video Editor Interface
Sets up all the necessary state variables, UI theme, and data structures

The initialization process:
1. Stores parent window reference and shorts folder path
2. Initializes video playback state variables
3. Sets up timeline state and interaction controls
4. Configures professional editing features (snap, magnetic timeline)
5. Defines track structure for multi-track editing
