I have seen this video on YouTube which has a white background effect with proper video quality.
How could I do this?

You need a white backdrop with the appropriate backdrop stands! For the backdrop, you have two choices:
To light this scene, you'll need three lights: key light + fill light to light your actor, and third a Fiilex light, like this one, to place on the ground behind your sitting talent, and pointing upward towards the backdrop.
It's best to turn off all interior lights and block out the windows and only light the scene using these three lights.
