""" 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 """ import sys import os import threading import time from datetime import datetime import cv2 import numpy as np from PIL import Image from PyQt6.QtWidgets import ( QApplication, QMainWindow, QWidget, QVBoxLayout, QHBoxLayout, QGridLayout, QSlider, QPushButton, QLabel, QFrame, QTabWidget, QScrollArea, QSplitter, QFileDialog, QMessageBox, QSpacerItem, QSizePolicy, QLineEdit, QSpinBox, QDoubleSpinBox, QComboBox, QCheckBox, QProgressBar, QTextEdit, QGroupBox, QToolButton, QButtonGroup, QDockWidget, QStyleFactory, QStackedWidget, QStackedLayout ) from PyQt6.QtCore import ( Qt, QUrl, QTimer, pyqtSignal, QPropertyAnimation, QEasingCurve, QRect, QThread, pyqtSlot, QObject, QRunnable, QThreadPool, QMutex, QSize, QEvent ) from PyQt6.QtMultimedia import QMediaPlayer, QAudioOutput from PyQt6.QtMultimediaWidgets import QVideoWidget from PyQt6.QtGui import ( QPalette, QColor, QFont, QIcon, QKeySequence, QShortcut, QPixmap, QPainter, QBrush, QPen, QPolygon, QAction, QCursor ) #
