Python creating video from images using opencv
You can use this pip package. It provides CLI commands to make video from images.
img_to_vid.py -f images_directory
You can read the frames and write them to video in a loop. Following is your code with a small modification to remove one for loop.
import cv2
import numpy as np
# choose codec according to format needed
fourcc = cv2.VideoWriter_fourcc(*'mp4v')
video = cv2.VideoWriter('video.avi', fourcc, 1, (width, height))
for j in range(0,5):
img = cv2.imread(str(i) + '.png')
video.write(img)
cv2.destroyAllWindows()
video.release()
Alternatively, you can use skvideo library to create video form sequence of images.
import numpy as np
import skvideo.io
out_video = np.empty([5, height, width, 3], dtype = np.uint8)
out_video = out_video.astype(np.uint8)
for i in range(5):
img = cv2.imread(str(i) + '.png')
out_video[i] = img
# Writes the the output image sequences in a video file
skvideo.io.vwrite("video.mp4", out_video)
You are writing the whole array of frames. Try to save frame by frame instead:
...
for j in range(0,5):
video.write(img[j])
