Remember to:

  • Ask your Python question, not if you can ask or if there's an expert who can help.
  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

ffmpeg converts your apng to gif quite easily, here's me doing it through the python repl

#

you really should familiarise yourself with ffmpeg, it's a very useful tool

#

there is no module, isn't it fine that it's an external tool?
yes, it's transparent, and ffmpeg has a ridiculous amount of features, sure it can upscale, it'll take you some googling though

#

imagemagick is a command line tool just like ffmpeg, it's not as familiar to me though

#

it's a command line tool, you use it from the command line, when run with no arguments (i.e. double clicking) it naturally has no job to perform and closes

#

or, it does perform its single job when it has no arguments: it displays a help screen and then immediately finishes - you will only keep that help screen if you run it from the command line

#

you'll have to demonstrate that for me or there's not much i can do

#

run ffmpeg with no arguments, what version does it say it is?

#

from where was it acquired?

#

i've not seen a version number like that, i guess it's an automatic build rather than a release build

#

sure enough, i download an automatic build, and its gif output is broken...

#

i'm going to investigate a bit

#

my guess is that new versions of ffmpeg (mine was from 2020) are more strict in how gif palettes are handled, somehow, and i got it working with this command:

ffmpeg -i input.png -filter_complex "[0]split[a][b];[a]palettegen[p];[b][p]paletteuse" output.gif```
got it from here https://trac.ffmpeg.org/ticket/7923
#

ah not quite, it's got artifacting...

#

well, if you don't want to troubleshoot it further, you could always acquire my old version, or see how imagemagick fares C:\Users\nesfi>ffmpeg ffmpeg version 4.3.1 Copyright (c) 2000-2020 the FFmpeg developers built with gcc 10.2.1 (GCC) 20200726

#

huh, i saw a pink outline

#

i read that filtering is required to preserve transparency at rescale, google around and you'll find stuff
