My thanks for your reply. I'll take your notes into account.
About the font things, well the reason behind them is to emulate the characters' voices. I figured that names aren't part of the speech so they're left in this 'universal' font. Or you could alternatively take it as the narrator's font, who says who's speaking.
And as for the commercial reuse, well yeah I understand it's a legitimate and big concern. Youtube is really wack on this side, they can put ads even on non YT-partner channels if their bots find something. Even so I will try my best to meet the non-commercial use requirement.
