The video shows a first-person view of a player in a Minecraft game. The player is standing in a grassy area with trees in the background. The player's inventory is visible at the bottom of the screen, showing various items such as blocks and tools. The player is holding a block in their hand and places it on the ground, creating a wall. The player then selects a different block from their inventory and places it on top of the wall, continuing to build. The video is a demonstration of how to build walls in Minecraft.
