These are some scripts to generate Himawari-8 GIFs using python and ffmpeg.
Here is an example of the output you can expect: https://imgur.com/Zonhp5y

The main difference between the original and this version is that this version works on Windows because it is almost entirely written in python. For generating the GIF from the image sequence, ffmpeg is called from a very simple batch file, that can be rewritten as a shell script for Linux users.
These scripts are comptible with python 2.7. For an updated version that is compatible with python 3.6+, see this fork.

Open and edit fetch_many.py. Especially select the zoom and directory where the images should be saved. The directory has to end with a '/' and has to exist already. Execute this script with python and wait until it's done.
This substitutes the "no image"-images at 14:40 and 2:40 with an interpolation of the images before and after the gap. Open and edit interp.py. The settings should match those from step 1.
Open and edit label_and_rename.py. Here you can determine how the timestamp should look. The images will be saved as "image1.png", "image2.png", because that makes life easier for step 4.
If your are on Windows, open and edit makegif.bat. If you use Linux, it should be fairly straigthforward to rewrite this into a shell script. Set the directory names you used in the previous steps. Make sure the scale is right (multiply the zoomlevel of step 1 with 550 to get the correct scale). Run this script and enjoy your GIF!
