White Clouds Transform into Ominous Storm Clouds

Clouds billow and roll across the sky on a sunny day. The shot begins with bright, puffy white clouds that are contrasted against a deep blue sky. As the video progresses, dark gray storm clouds roll in, obscuring the sun. The camera is mostly static with some slow panning, giving a wide shot of the sky above. This clip is perfect for projects that need to convey the passage of time or dramatic changes.
