You should setup the KK 2.0 for X motor layout.
As i cannot see your fc in the video, make sure the orientation of the board is as per an x shaped frame and the motors are rotating in the right direction with correct props.

Well what i do is fit the prop on motor 1 and give it a spin and check the thrust direction, it should be downwards, and accordingly fit rest of the props.
Most of the props have size written on them blades of the props, and thats the side facing upwards,

Anyways check the link below

Another good way of checking prop rotation just by looking at the prop is to see which side the pitch rises on the blade. The direction it rises is the direction of the prop’s rotation as the blade catches the air on the top and pushes it downwards to create lift. Have attached some pics for help. Happy flying…

A good way to check motor rotation is to wrap a Postit (or any piece of paper stuck with tape) around the motor shaft.
