Creating an animated gif with PIL that does not loop

Question

I've been able to create animated gifs that loop infinitely using PIL without an issue, usually ending up with something like

final_image.save('/path/to/images/some.gif, save_all=True, append_images=frames_images, duration=frame_speeds, loop=0)

I am now in a situation where I would like to create a gif that plays a single time and does not loop. The PIL docs I used¹ are pretty clear about the loop argument but don't offer any advice for my situation:

loop : int
The number of iterations. Default 0 (meaning loop indefinitely).

0 causes it to loop infinitely. 1 causes it loop once (play two times). I have tried options like -1 and None but can't find a working argument. I am currently using a work around where I invoke gifsicle afterwards to remove the loop entirely but was hoping PIL would support this natively

Answer 1

If you are using Pillow, you can leave out the loop argument. That'll ensure no loop. https://pillow.readthedocs.io/en/stable/handbook/image-file-formats.html#saving Also to note, duration is in milliseconds, not seconds.

What a funny coincidence. I have a code that shows a GIF one iteration and then freezes until the mp3 file is finished... but I need a GIF that loops infinitely.

The only difference is I used the library moviepy.

Working solution:

from moviepy.editor import *
import moviepy.editor as mp


# Import the audio(Insert to location of your audio instead of audioClip.mp3)
audio = AudioFileClip("PATH/TO/MP3_FILE")

clip = VideoFileClip("PATH/TO/GIF_FILE").set_duration(audio.duration)


# Set the audio of the clip
clip = clip.set_audio(audio)


clip_resized = clip.resize((1920, 1080)) 


# Export the clip
clip_resized.write_videofile("movie_resized.mp4", fps=24)
