#Python 🐍 – Export Video Frames as Images from a video file πŸŽ₯

Hi !

I can’t believe I didn’t write about this before. I usually do this, at least 2 times per month, and hey, now it’s on the blog for my future reference.

Simple Scenario: Open a video file and export each frame as an image.

Some notes:

  • The sample uses OpenCV. I wrote a lot how to install and use OpenCV.
  • The video file must be in the same folder of the python file.
  • Create a folder [IMG] in the same path to store the exported images.

Then you run it and have something like this

exported frames from a video file

And a super simple piece of code

import time
import cv2
# Open Video File
video_capture = cv2.VideoCapture("Video.mp4")
time.sleep(1.0)
# frame counter
i = 0
while True:
ret, frame = video_capture.read()
if ret:
i = i + 1
imgNumber = str(i).zfill(5)
name = './img/frame_' + str(imgNumber) + '.jpg'
print ('Creating…' + name)
# writing the extracted images
cv2.imwrite(name, frame)
else:
break
video_capture.release()
cv2.destroyAllWindows()

Happy coding!
