Playing a video from file with color BGR, RGB, GRAY, HSV in OpenCV

import cv2

capture = cv2.VideoCapture('video_1.mp4')


while True:
    ret, frame = capture.read()
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    HSV = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV)
    RGB = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)

    cv2.imshow('Normal plus BGR', frame)
    cv2.imshow('Gray', gray)
    cv2.imshow('HSV', HSV)
    cv2.imshow('RGB', RGB)


    if cv2.waitKey(1) == 27:
        break
cv2.destroyAllWindows()
