🧠 How It Works

• The app uses Pillow (ImageGrab) to take screenshots repeatedly.
• Converts images to frames using NumPy and OpenCV.
• Writes frames to an MP4 file via cv2.VideoWriter.
• (Optional) Records system audio using PyAudio.
• The Tkinter GUI controls start, stop, and area selection.

⚠️ Known Issues

• Audio recording may not work on some systems (especially Linux without proper PulseAudio/ALSA setup).
• High resolutions (1080p+) may result in lower frame rates on older CPUs.
