I want to read frame by frame from existing video, and create new video from these frames.
In my real project I want to change each frame before making the new video but for simplicity's sake of this question I just want to create new video from the same frames without any change.
This code is working for me:
import cv2 vidcap = cv2.VideoCapture('input_video.mp4') vidwrite = cv2.VideoWriter('output_video.mp4', cv2.VideoWriter_fourcc(*'MP4V'), 30, (1920,1080)) success,image = vidcap.read() while success: vidwrite.write(image) # write frame into video success,image = vidcap.read() # read frame from video vidwrite.release() cv2.destroyAllWindows() The strange thing is that the output video is twice bigger than the input video
