I thought the videos are not for transporting general ideas, but to
show the daily usage of guix. And that is using the command line. By
showing common tasks the general idea gets transported (i.e. while
showing guix package -i, guix package --list-generations, guix package
--roll-back the idea of transactional package management is conveyed,
without much abstract words).

When I thought about translations, I thought only about the speech and
subtitles. Of cause you are right, the command line should be localized
too!

When I said screencasts I first thought of handmade ones within well
prepared (and documented) environments and a script/stage
directions and script for automatic cutouts from the raw recordings.

Then I thought of this puppet we have for qemu-tests: Is it possible to
use it in order to controll the virtual machine, screencast it and get
back certain events like terminal keywords in order to start/stop/pause
the cast?

This is my first time I heard of asciicasts. You mean the program
asciinema and it's protocol asciicasts (https://asciinema.org/)? That
looks cool. Can it be used to produce rendered films too?

Automating the process as much as possible is a good idea. Can we get
that bitwise reproducible? :-)

Yes, that site looks good, I watched videos from it in the past.

We don't have a Mediagoblin package yet :-)
