The video shows a first-person view of a Minecraft player building a wall. The player places blocks of stone and other materials to create a straight wall. The wall is made up of several rows of blocks, with some blocks placed on top of others to create a layered effect. The player's inventory is visible at the bottom of the screen, showing the different materials they are using to build the wall. The environment around the wall is a flat, grassy area with a clear sky above.
