How would you do this?

Hey guys!
I'm sorry, I know there are tons of posts asking "how would you do this?", but I'd like to apply something like this in my job, and I'm not sure where to start.

Also I'd like to ask about the frame rate, it's just about posterize time, right?

Thank you guys in advance!
