I have an algorithm, which after each iteration creates a matrix. After some operations on matrix it is plotted to the user. if I run program 6 times I will get:

My goal is to changing image dynamically, like a movie.

I have no idea from which side to start. I found some ways of creating video from images in python and then wrap it in the video player. But it seems to be a bit complicated and it is impossible to see the changes while algorithm is working. Are there any suggestions how to do it?

You can use FFMPEG

def convert():

    os.system("ffmpeg -r 1 -i img%01d.png -vcodec mpeg4 -y movie.mp4")

Alternatively, you can use ImageIO to generate a GIF. You can set the parameters for duration of each frame.

import imageio

with imageio.get_writer('/path_to_video.gif', mode='I') as writer:

    for filename in filenames:

        image = imageio.imread(filename)

        writer.append_data(image)

Read the manual on website for more detailed instructions.

Or with cv2,

import cv2



img1 = cv2.imread('1.jpg')

img2 = cv2.imread('2.jpg')

img3 = cv2.imread('3.jpg')



height , width , layers =  img1.shape



video = cv2.VideoWriter('video.avi',-1,1,(width,height))



video.write(img1)

video.write(img2)

video.write(img3)



cv2.destroyAllWindows()

video.release()
