I am assisting in making a wiki for an old game, and we ripped the avatar GIFs from the games shop and want to have a catalog of them. What I need to do is to crop all the borders which are identical from 3,170 GIFs and maybe make background transparent.

I haven’t used python in years, but I managed to cobble up something that almost works as a single image test, only issue is that it crops and outputs only the first frame:

from PIL import Image

if __name__ == "__main__":
    input_loc = "AvatarShopImages/80001.gif"
    output_loc = "Output/80001.gif"
    im = Image.open(input_loc)
    im = im.crop((4, 4, 94, 94))
    im.save(output_loc)

If it looks weird, it is because I copy/pasted some code and edited a lot out of it.

      for i in $( ls *.gif ); do fmpeg -i $i -vf “crop=w:h:x:y” cropped_$i; done

      This runs on Linux/Mac or on WSL on windows Make sure there are no spaces in the filenames.

      If they’re all the same size and need cropped to the same size you could drop them all in one folder and run the ffmpeg command with *.gif. That should do all of them.

      You’d have to find a way to automate the output though.
