Save Frames from Video OpenCV-python

Question

I want to save frames from a video. My problem is that saved frames keep overwriting and only last frame saved at the end. Here is my code

import cv2

vc = cv2.VideoCapture('111.mp4')
c = 1
if vc.isOpened():
    rval, frame = vc.read()
else:
    rval = False
timeF = 30
while rval:
    rval, frame = vc.read()
    if not rval: break
    if (c % timeF == 0):
        cv2.imwrite('/home/benson/Image/imagename.jpg', frame)
    c = c + 1
    cv2.waitKey(1)
vc.release()

Answer 1

You already have a counter available, why aren't you using it?

cv2.imwrite('/home/benson/Image/imagename_{:04d}.jpg'.format(c), frame)

Good luck
