The video shows a first-person view of a player in Minecraft placing and removing blocks to create a window. The player starts by placing a black block in the center of a window frame, then adds a white block on top of the black block to represent the window's glass. The player repeats this process several times, alternating between placing and removing blocks to create the window's structure. The window frame is made of white blocks, and the glass is represented by black blocks. The player's inventory is visible at the bottom of the screen, showing the blocks they are using.
