* This website uses fullPage.js [1], which is a widely used javascript library for such full screen presentation (for instance Apple use it in their Mac Pro promo page [2]). You can get around it's API if you know a little HTML and a little javascript, but it's still a lot of manual work. And the neatier features are locked behind a (totally justified) paywall.
* One neat generator I know is Jack Qiao's Expose[3] which he mainly uses in his travel photography website [4]. Check out those sweet cinemagraphs ! Unfortunately it is a command-line program which may be a bit obtuse to non-developer (especially on Windows), and the text placement has to be set manually
* Shameless plug: as a side project, I made a clone of Expose in Python [5] (demo [6]) with no video support but explicit Markdown support (so you can embed maps, youtube videos and others ). It's still a command line app, but I'm working on a second version that uses Electron and has a more WYSIWYG approach. It is still very much a side project though.
* You could look at some web-based presentation framework. Slid.es [7] is an WYSIWYG builder for the reveal.js library [8]. It's mainly used for Powerpoint-ish presentation (ex. [9][10]), but with a touch of creativity you can do neat thing, like this portfolio [11].

That's when I learnt about Pageflow.
Pardon the late reply, I have set up fairly aggressive noprocrast settings which means that I am not always in a position to reply immediately.
Pageflow is especially neat: the pages load fast, the pricing is friendly, and the company can self-host the page. Thank you for taking the time to reply- will be checking this out with my buddy over the weekend.
PetitPrince also provides appealing options, some more noob friendly than the others... I will take the time to download the git repos and see just how successful I can be installing/deploying the code.
All in all, thank you guys for reaching with helpful suggestions.
