Looping marquee which accelerates on scroll

Hey guys, hope y’ll are doing fine. So, I tried to recreate the marquee effect which is on loop but when you scroll the speed of the marquee increases giving it a smooth effect. For reference this is the site which inspired me to try this out. It’d be awesome if anyone can guide me through this cause I am pretty sure after tons of research that this effect will not be possible without the use of custom code(In which I’m noob). Thank you.
