Hi Guix! I copy/pasted my installationSscript video directory, adding Björn's script to generate the videos. I am inside the cointainer, removed the commented line about not cleaning after creating a slide video, and my final video behaves properly, even with the appropiate fonts, like the one I sent to my mentors. I can put it again in my ipfs and then maybe someone can fetch it and share it. Shall I remove Björn's directory and push mine's so that you check again if it works for you? Maybe I'll write back asking for help with the signing stuff, since I am new to gpg.
Regards :) Laura
