This Unreal Engine 5.4 video is about Video Quality Options.
We start by talking about the Video Quality Options in the Game User Settings Class, which we use to create an Enum. And then, in the Blueprint Function Library, we create Get and Set Video Quality Functions. Following that, we create the new Video Quality Row Widget Blueprint, which has some text, and a few buttons to cycle through the Video Quality Options. Lastly, we create the Video Quality Row Widget Blueprints in the Video Options Widget Blueprint and make sure they update as appropriate.
