Python – Writing to video with OpenCV
In this article, we will discuss how to write to a video using OpenCV in Python.
- Import the required libraries into the working space.
- Read the video on which you have to write.
cap = cv2.VideoCapture("path")
- Create a output file using cv2.VideoWriter_fourcc() method
output = cv2.VideoWriter(“path”,cv2.VideoWriter_fourcc(*’MPEG’),30,(1080,1920))
- Then edit the frames of the video by adding shapes to it (for the example given here, the same can be applied to any other technique.).
cv2.rectangle(frame, (100,100), (500,500), (0,255,0), 3)
- Then write the video.
