The Guix videos at https://guix.gnu.org/videos/ were made with a
pipeline that assembles slides and scripted text:


The core is a little Guile thing that interprets a scripted session
(like this: [1]) and produces a bunch of frames that are then assembled
with ffmpeg.

We built this pipeline to allow for easy translation of these videos.
To manage expectations: the intended effect is that of a narrated
slideshow presentation with little shell demos here and there.

Maybe parts of this workflow could be useful to those that would like to
build videos for Emacs.
