You could consider using an external tool like ffmpeg to merge the images into a movie (see answer here) or you could try to use OpenCv to combine the images into a movie like the example here.
您可以考虑使用 ffmpeg 等外部工具将图像合并为电影（请参阅此处的答案），或者您可以尝试使用 OpenCv 将图像合并为电影，例如此处的示例。
I'm attaching below a code snipped I used to combine all png files from a folder called "images" into a video.
我在下面附上了一段代码，我用来将名为“图像”的文件夹中的所有 png 文件合并到视频中。
import cv2
import os
image_folder = 'images'
video_name = 'video.avi'
images = [img for img in os.listdir(image_folder) if img.endswith(".png")]
frame = cv2.imread(os.path.join(image_folder, images[0]))
height, width, layers = frame.shape
video = cv2.VideoWriter(video_name, 0, 1, (width,height))
for image in images:
video.write(cv2.imread(os.path.join(image_folder, image)))
cv2.destroyAllWindows()
video.release()

Thanks , but i found an alternative solution using ffmpeg:
谢谢，但我找到了使用 ffmpeg 的替代解决方案：
def save():
os.system("ffmpeg -r 1 -i img%01d.png -vcodec mpeg4 -y movie.mp4")
But thank you for your help :)
但是谢谢你的帮助:)
