#gifsicle — Public Fediverse posts

I have this very simple #Python script that uses #imageio to convert all PNG files on a folder into a #GIFAnimation, and this is a #FreeSimpleGUI version of it (I usually run a command line version).

As I usually run #gifsicle on the command line after creating a GIF, I decided to update it to add #pygifsicle to do it for me and save a step.

Here is the magic incantation I've found creates the best animated gifs for use as emojis in Slack. Powered by @kornel 's gifski:

ffmpeg -i INPUT.gif -vf "format=yuv420p"  -f yuv4mpegpipe - | gifski -W 128 -H 128 -Q 55 -o OUTPUT-compressed.gif -

Make quality -Q vary until size is just below ~128k. For some reason, Slack's limit is not exactly 217, but not 128000 either.

I’ve done a couple of #AnimatedGifs of #sunsets before and the conditions seemed right today. The program I used was the #Unix commands #convert and #gifsicle to reduce the image size which produces no #aliasing artefacts that you can get with something like #Gimp. Still, you can see how the #Sun sets at an oblique angle at this #latitude.
