(Just to document)
I extracted the frames of an animated gif and used
Kindle Comic Creator to produce a KF8 ebook.
Following the
Converting Comics and Manga OP's instructions, I then used the plugin to convert from the KF8's opf to the KFX format.
My goal was to use the
« fast continuous page turns » manga feature to reasonably simulate the gif animation.
It pretty much worked!
