We'll utilize the cv2.VideoWriter method to write videos to file using OpenCV., try this . it's working for me. import numpy as np import cv2 cap = cv2.VideoCapture(0) # Define the codec and create VideoWriter object #fourcc = cv2.cv.CV_FOURCC(*'DIVX') #out = cv2.VideoWriter('output.avi',fourcc, 20.0, (640,480)) , But for videos, we need to toil a bit harder. We need to create a VideoWriter object. First, we should specify the output file name with its format (eg: output.avi). Then, we should specify the FourCC code and the number of frames per second (FPS). Lastl,Often, we have to capture live stream with camera. OpenCV provides a very simple interface to this. Let's capture a video from the camera (I am using the in-built webcam of my laptop), convert it into grayscale video and display it. Just a simple task,Get current height of frame. height = cap.get(cv2.cv.CV_CAP_PROP_FRAME_HEIGHT) # float. # Define the codec and create VideoWriter object. fourcc = cv2.cv.CV_FOURCC(*'X264'). out = cv2.VideoWriter(FILE_OUTPUT,fourcc, 20.0, (int(width),int(height)))
