Hi Laura and sirgazil,
I was able to build videos in 01-installation-from-script following the
updated informations in the README, that is:
1. environment.sh
2. install-fonts.sh
3. cd 01-installation-from-script/ && buildall.sh
the only "strange" message I see during the build is
--8<---------------cut here---------------start------------->8---
convert: profile 'icc': 'RGB ': RGB color space not permitted on grayscale PNG `01-installation-from-script/en_US/out/secondCli-0148.png' @ warning/png.c/MagickPNGWarningHandler/1667
--8<---------------cut here---------------end--------------->8---
but AFAIK we should ignore it
https://github.com/ImageMagick/ImageMagick/issues/884#issuecomment-451084328
(or make it quiet?)

same here: each video built in 01-installation-from-script/en_US/videos/
fails to be played in Firefox 60.3.0esr
Chromium 72.0.3626.119 can play all them, but colours are altered like
with Totem from sirgazil tests; chromium auto-rescales the different
aspect ratio in cli and noCli videos

mpv also plays the video with unaltered colours but is non able to
manage the different aspect ratios: I have to switch to full-screen (so
auto-rescales) in cli sessions video parts and switch back to normal
screen when video svitches to noCli
[...]
about aspect ratio of videos, mediainfo reports:

we should find a way to scale all "cliyes" videos to 1920x1080 pixels
no idea why colours are altered in the browser (our main target, I
suppose)
..I have to stop for today
HTH!
Thanks!
