How to create a video from images?

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:



a bunch of images



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()
