  13.  
  14. # Loop through all the video files in the directory

  22.         # Check if the current frame contains the match sentence

  32. for video_segment in video_segments:
  33.     # Open the video segment
  34.     segment = cv2.VideoCapture(video_segment)
  35.  
  36.     # Read the video segment frame by frame
  37.     success, frame = segment.read()
  38.     while success:
  39.         # Write the current frame to the output video
  40.         output_video.write(frame)
  41.  
  42.         # Read the next frame
  43.         success, frame = segment.read()

  49. This code uses the glob module to loop through all the video files in a given directory, and the cv2 module (which is part of the OpenCV library) to read and write the video files. The code reads each video file frame by frame and checks if the match sentence is present in the current frame. If the match sentence is found, the video segment containing that frame is added to a list of video segments to concatenate. Finally, the code concatenates the video segments by reading each segment frame by frame and writing the frames to an output video.
