• Keyframing: Set focus/desaturation/mode for individual frames (videos)
• Different modes: Supports Color, Half-color, and Gray anaglyph modes
• Frame interpolation: Linear or stepped parameter transitions
• Hardware acceleration: Uses OpenCL (via OpenCV UMat) if available
• Multithreaded video export with progress dialog and cancel support
• Intuitive PySide6 GUI with keyboard shortcuts for speedy workflow
• Multiple FPS Methods: Custom FPS, Frames and Duration Based FPS and OpenCV Based FPS
