# make a video where each frame is the frame number

writer = cv2.VideoWriter("frame_numbers.mp4", cv2.VideoWriter_fourcc(*"mp4v"), 30, (1920, 1080))

for i in range(6572):
    frame = numpy.zeros((1080, 1920, 3), dtype=numpy.uint8)
    cv2.putText(frame, str(i), (500, 500), cv2.FONT_HERSHEY_SIMPLEX, 10, (255, 255, 255), 2)
    writer.write(frame)
    print(i, end="\r")

writer.release()
