Programmatically generate video or animated GIF in Python?


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 imageioimages = []for filename in filenames:    images.append(imageio.imread(filename))imageio.mimsave('/path/to/movie.gif', images)

For longer movies, use the streaming approach:

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


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

import globfrom PIL import Image# filepathsfp_in = "/path/to/image_*.png"fp_out = "/path/to/image.gif"# https://pillow.readthedocs.io/en/stable/handbook/image-file-formats.html#gifimg, *imgs = [Image.open(f) for f in sorted(glob.glob(fp_in))]img.save(fp=fp_out, format='GIF', append_images=imgs,         save_all=True, duration=200, loop=0)

See docs: https://pillow.readthedocs.io/en/stable/handbook/image-file-formats.html#gif


Well, now I'm using ImageMagick. I save my frames as PNG files and then invoke ImageMagick's convert.exe from Python to create an animated GIF. The nice thing about this approach is I can specify a frame duration for each frame individually. Unfortunately this depends on ImageMagick being installed on the machine. They have a Python wrapper but it looks pretty crappy and unsupported. Still open to other suggestions.
