import cv2:

• OpenCV library for image and video processing.
• Used here for writing video files (cv2.VideoWriter) and color conversion (cv2.cvtColor).

import numpy as np:

• NumPy library for handling arrays.
• Used here to convert the screenshot (Pillow format) to a format suitable for OpenCV.

import pyautogui:

• Library to automate and interact with the screen.
• Used here to take screenshots of the screen.
