Programmatically generate video or animated GIF in Python?


I have a series of images that I want to create a video from. Ideally I could specify a frame duration for each frame but a fixed frame rate would be fine too. I"m doing this in wxPython, so I can render to a wxDC or I can save the images to files, like PNG. Is there a Python library that will allow me to create either a video (AVI, MPG, etc) or an animated GIF from these frames?

Edit: I"ve already tried PIL and it doesn"t seem to work. Can someone correct me with this conclusion or suggest another toolkit? This link seems to backup my conclusion regarding PIL:

I"d recommend not using images2gif from visvis because it has problems with PIL/Pillow and is not actively maintained (I should know, because I am the author).

Instead, please use imageio, which was developed to solve this problem and more, and is intended to stay.

Quick and dirty solution:

import imageio
images = []
for filename in filenames:
imageio.mimsave("/path/to/movie.gif", images)

For longer movies, use the streaming approach:

import imageio
with imageio.get_writer("/path/to/movie.gif", mode="I") as writer:
    for filename in filenames:
        image = imageio.imread(filename)

Here"s how you do it using only PIL (install with: pip install Pillow):

import glob
from PIL import Image

# filepaths
fp_in = "/path/to/image_*.png"
fp_out = "/path/to/image.gif"

img, *imgs = [ for f in sorted(glob.glob(fp_in))], format="GIF", append_images=imgs,
         save_all=True, duration=200, loop=0)
