The video captures a dramatic scene of a large, towering cumulonimbus cloud formation over a vast, flat landscape with distant mountains. The cloud is expansive and dense, with a flat top and a dark, rain-bearing base. Rain can be seen falling from the cloud, creating a striking contrast against the bright blue sky. The landscape below appears arid, with sparse vegetation, emphasizing the grandeur of the cloud formation. The overall atmosphere is one of impending weather change, with the cloud dominating the sky and casting shadows on the ground.
A vast, open landscape with a dry, brown ground stretches out under a clear blue sky. A massive, white cloud formation dominates the sky, growing larger and more prominent as the frames progress.

The cloud's growth is steady and continuous, with no other significant changes or movements in the background. The cloud's expansion reaches its peak, covering a significant portion of the sky and casting a shadow over the distant mountains.
