Video corrupted after using Canny then writing. Can you guys spot the mistake

edit

I solved problem. You are missing parameter in cv2.VideoWriter.

import cv2
import numpy as np
cap = cv2.VideoCapture('video.mp4')
frame_width =  int(cap.get(3))
frame_height = int(cap.get(4))
out = cv2.VideoWriter('manipulated_video.avi',
                      cv2.VideoWriter_fourcc(*'MJPG'), 25,
                      (frame_width,frame_height), False)

while(cap.isOpened()):
    ret, frame = cap.read()
    if ret == True:
        edges = cv2.Canny(frame, 100, 200)
        out.write(edges)
        cv2.imshow('Edges', edges)

        if cv2.waitKey(25) & 0xFF == ord('q'):
            break
    else:
        break

cap.release()
out.release()
cv2.destroyAllWindows()
